Professor Wen's main research interests include soft condensed matter physics, electrorheological (ER) and magnetorheological (MR) fluids, field-induced pattern and structure transitions, micro- and nano-fluidic controlling, microsphere and nanoparticle fabrications, thin film physics, band gap materials, metamaterials and nonlinear optical materials. 

Electrorheological (ER) and Magnetorheological (MR) Fluids

ER fluids denote a class of materials consisting of nanometer to micrometer sized dielectric particles dispersed in a liquid, whose rheological properties are controllable by an external electric field. In particular, they can reversibly transform from a liquid to a solid within one hundredth of a second. While in the solid state (with the electric field applied), the strength of that solid, measured by the yield stress, is the critical parameter that governs the application potential of the ER fluids.

Microfluidic devices are new generation micro-chips which will be widely used in Bio-microchip, Chemical reaction technology, lab-on-a-chip and other research areas. Our microfluidic devices are mostly associated with ER techniques developed recently in our laboratory. The merits of which are its fast response time, digitalization, easily controlling, and good reliability.

A specific class of planar conducting fractals possesses a series of self-similar resonances, leading to multiple gaps and pass bands for electromagnetic waves over an ultra-wide frequency range. The important feature of this material is that it exhibits not only the tunable multiple bands but also subwavelength properties in lateral dimensions, as well as simulates the functions usually exhibited by three-dimensional photonic crystals.

温维佳：智能材料里的大世界

 

法国作家阿纳托尔•法朗士曾说，好奇心造就科学家和诗人。同样，好奇心也是无数科学发现的源泉。1月9日，2014年度国家科学技术奖励大会上，由香港科技大学温维佳主持完成的“巨电流变液结构和物理性质的研究”项目获得国家自然科学奖二等奖，这是当年由香港科学家完成的两个获奖项目其中之一，同时也是一项最初源于科学好奇产生的成果。

电流变效应在人们眼里最初只是一个科学好奇，但随着人们对电流变流体应用的预期，使得电流变流体自60年前发现以来，成为一个持续的研究领域。在科研工作者眼里，电流变流体是一种极具前景的智能材料，它的流变特性可以根据施加的电场而改变，因而在工业上具有广阔的应用前景。

1995年在中国科学院获取博士学位后，温维佳加入香港科技大学，其间他又在洛杉矶加州大学做博士后研究。扎实的学习、科研经历为他日后从事科研奠定了牢固的基石。这些年，他的研究领域涉及凝聚态物理、微米及纳米材料的研究、先进功能结构材料、纳米电（磁）流变液、微流控制、软物质物理及光电子功能结构材料等。而其中，主要的研究对象就是智能流体。

“智能流体是一种介电微粒与绝缘液体混合而成的复杂流体。由于它具备了黏度随电场变动的特质，在汽车、工业及航天等领域均带来广阔的应用前景。智能流体可用于制造阻尼器、减震器、制动器、离合器、阀、方向及速度控制器以至虚拟现实系统等装置。”温维佳和许多科学家一样，对流变效应的基本机制进行了深入研究。

在电场作用下，一些原子或分子的电极化可以通过两种方式实现。一种是之前提到的传统电流变效应的诱导极化过程。这是一种介电电流变效果。另一种是通过排列自身原有的随机方向分子偶极子。这第二个过程带来了巨电流变效应。温维佳认为，比较这两种类型的极化机制的显著特点及其对于电流变效应的影响很有意义。

随着科研的深入，温维佳发现，巨流变流体的强电反应在多种微流芯片中特别有用。就这样，在发现的巨流变效应与其在纳米粒子和动力学的科学基础领域的共同吸引下，这个领域的一个新的研究方向在他面前展开。

同时，在纳米尺度的分子偶极子操纵为进一步探索提供了广阔的视野。特别是，自发涨落效应的分子偶极细丝形成及产生宏观长度的分子偶极细丝的可能性，使得不论是从理论还是从试验研究出发，都非常有意义。在获得国家自然科学基金委员会颁发的2000年海外青年学者合作研究基金资助的40万元外，他还获得了中科院物理研究所50万元研究经费资助，这些资金支持他带领团队进行智能流体的研究。于是，在温维佳和他在香港科技大学所带领的团队的共同努力下，“巨电流变液结构和物理性质的研究”前景逐步明朗。

实际上，这些年，温维佳所领导的这支研究团队，早已在软物质材料、电流变液研究等方面取得了成就，在国际上引起了高度的关注。而作为软凝聚态物理专家的温维佳，在国际上早已声名远扬，他已获得14项美国专利和8项中国专利，发表的200多篇论文均被SCI收录。

温维佳说：“巨电流变微流逻辑门使得制成可以实现高水平智能性能的综合复杂微流电路系统成为可能。”在研究中，具有低的无电场黏度，100kPa左右的屈服应力，并且在长期使用过程中不表现出颗粒聚集或沉淀现象的理想巨电流变流体，还是一个迫切需要解决的挑战。但温维佳表示：“这个目标的实现，可以扩大巨电流变流体在主动控制机械设备如减震器、离合器、制动器及锁中的应用。”

电流变流体的这方小小的世界里，充满了无限精彩，温维佳和他的团队正全力以赴，让科学的探索成为可能。

溫維佳:香港科研「缺錢不缺人」

【文匯網訊】(記者 劉凝哲 北京報道)溫維佳教授在北京參加2014年度國家科技獎勵大會期間，接受本報獨家專訪時直言，如今香港的科研經費很少，內地的科研經費很多卻無法申請，「香港有許多優秀的頭腦，但研究經費不足」。200萬經費在內地的知名科學家看來，幾乎「不算事兒」，但對於溫維佳等香港科學家卻十分關鍵。 

科幻「未來戰士」或成真 

還記得好萊塢電影《未來戰士2》中，那個隨時可由液體變身的超強未來機器人嗎?經過香港科技大學溫維佳教授「魔術師」團隊超過20載的研究後，製造科幻「未來戰士」的材料或將成真!智能材料--巨電流變液，在電的作用下，可在一毫秒內其硬度由液體變成如硬塑料般的固體。「巨電流變液的市場前景十分廣闊，可用於航天、航海、汽車甚至航母等等領域。成本低、用處大，希望它能盡快地被應用起來」，溫維佳說。 

溫維佳教授在北京參加2014年度國家科技獎勵大會期間，接受本報獨家專訪。他此次獲獎的項目是《巨電流變液結構和物理性質的研究》，在這看起來高深、專業題目的背後，卻是十分有意思的高科技。溫維佳向本報提供的視頻顯示，巨電流變液看起來只是乳白色的液體，但「啪」的一聲通電後，就會瞬間轉化為固體，可以抬起40公斤的重物，十分神奇。 

「巨電流變液平時像水一樣的，加了電場後，就變成一個固體。一般的電流變液，加入電場後，它的強度就像豆漿變成豆腐腦，強度變化不大。而我們這個巨電流變液材料，其硬度就是從豆漿直接變成硬塑料」，溫維佳說。他對電流變液的研究從1992年開始，前10年是基礎理論和實驗研究，在2003年時發現了巨電流變現象後，開始進行應用研究及產業化推廣等工作。 

溫維佳說，巨電流變液的主要競爭對手，是磁流變液。目前，磁流變液已在全球有著大規模應用，包括奧迪TT、法拉利等高端跑車和豪華轎車，都使用了磁流變液作為主動減震系統。然而，巨電流變液與磁流變液相比優勢明顯，磁流變液的強度變化從幾個Pa到幾十個KPa，而巨電流變液的強度變化則從幾個Pa到幾百個KPa。 

此外，成本低也是巨電流變液的一大優勢。溫維佳說，美國的磁流變液，半升的價格就要高達500美金，例如奧迪TT跑車四個輪子的選配減震器，需要2萬多元，而巨電流變液不僅效果更好，成本也低得多。目前巨電流變液已經取得美國專利、中國等專利，擁有完全的自主知識產權。 

談起巨電流變液的用途，溫維佳如數家珍。「這是個智能材料，是有智慧的，用處很大。加電之後，就能從軟的變成硬的。例如，水變成冰，要凍起來，時間長而且不可控，巨電流變液只用1毫秒可以把液體變成固體，而且是可逆的，去掉電場，就可以由固體變回液體，是可控的智能材料。」其用途包括越野車，飛機降落時的減震，高速列車的減震等等。 

溫維佳還透露，巨電流變液已在日本進行過微重力試驗，證明在微重力環境下，材料也具有同樣的效果，這可用於航天探月，例如月球車著陸月球時的減震等等。此外，在火箭對接、航天發射場、空間站機械臂等方面也有很多用途。此外，飛機在航母上起降時的減震問題，也可以由巨電流變液來解決。 

前沿先進技術，自然少不了別人的覬覦。溫維佳說，多家國際一流企業都開始使用巨電流變液的產品。此番來到北京參加國家科技獎勵大會，溫維佳希望能夠打開廣闊的應用市場，把巨電流變液產業做大做強。 

20餘載辛苦研究 每日工作15小時 

溫維佳對巨電流變液的研究始於1992年，當時他還是中科院物理所的博士。憑著對科學的熱愛和追求，溫維佳的研究從北京到香港從未間斷，直到今時他仍每天工作15個小時，去實驗室與團隊交流。「最欣慰的是，我們用了20多年，把基礎研究的成果做成了產品」，他說。 

2003年，是溫維佳科研生涯中至關重要的一年。他發現了巨電流變效應及解釋其機理的理論模型，為國際上並不順利的電流變液研究提出新途徑，使電流變液走向技術實用成為現實。溫維佳關於巨電流變液的論文在當年10月出版的《自然-材料雜誌》發表，立即受到該領域專家的廣泛關注。「新科學家」和「科學」等網站發表了評述文章。眾多媒體，如「華盛頓郵報」等也作了報道。 

國家科技獎勵官方給予溫維佳的成果極高評價。「該項目由香港科技大學的團隊經過長期積累與攻關完成。項目開始於國際電流變液研究熱潮因未能取得突破即將退潮之際，項目組從更寬廣的基礎研究角度，採取理論、實驗和樣品制備結合的方式，對外場作用下軟物質系統的結構和性質開展長期探索，弄清內在規律，制備出技術使用的高性能電流變液材料，並發展新的智能材料的制備與應用」。 

國家科技獎勵官方將溫維佳稱為「新電流變的創始人」，並稱他在國際學術界產生了重大影響。溫維佳的研究團隊曾在Nature materials、Advanced in Physics等國際著名期刊上發表論文80篇，獲得國內外專利8項，曾多次作為大會主席組織相關的國際及國內會議，並在國內外學術會議作特邀報告50多次。20多年以來，巨電流變液項目在基礎理論、新效應研究，材料制備和應用方面取得系統性的研究成果，處於國際領先水平，得到國際學術界廣泛認同。 

香港科研「缺錢不缺人」 

「如果每年給我200萬，能做的項目比現在多得多」，溫維佳說。200萬經費在內地的知名科學家看來，幾乎「不算事兒」，但對於溫維佳等香港科學家卻十分關鍵。他直言，如今香港的科研經費很少，內地的科研經費很多卻無法申請，「香港有許多優秀的頭腦，但研究經費不足」。 

溫維佳早前在重慶大學工作多年，後進入中科院物理所，再來到香港科技大學。比較這些機構的科研環境，他坦言，香港的環境更加自由，尤其是沒有如內地很多高校硬性規定的論文數量，令科學家可以沉下心來做自己喜愛的長期研究，而不是為所謂的分數奔命。但是，近年來內地的科研環境有很大改善，尤其是對知識產權的保護，令他深感欣慰。 

「如果我每年有200萬經費，能做的東西比現在多得多，我們的思維特別活躍。」，溫維佳遺憾地說。他的團隊現有10名成員，多是來自內地一流高校的頂尖學生。學生們的思維非常開闊，研究範圍十分廣泛，但卻備受科研經費短缺的困擾。 

溫維佳說，礙於當前規定，香港科學家無法申請內地科研經費，雖然通過聯合方式可以申請到一些支持，但經費與實驗團隊發展並不匹配。他希望港府可以向新加坡、韓國等學習，給科學家提供更多的經費，令他聘請更多研究人員，研發出更多的科學技術回報社會。 

溫維佳的團隊在研究巨電流變液同時，也發現很多其他的物理現象，並發展出新的科技產品。比如，他們研發的智能玻璃，看似透明玻璃，只要一按電鈕就變成磨砂玻璃，也可立即變回來。更有一種節能玻璃。另外一種平時透明的玻璃，太陽照射就會變成藍色，同時產生具有殺菌功效的雙氧，還能產生電能。 

現在溫維佳還在進行水科學研究。一如他20多年前對電流變液的研究，現在對水科學的研究也是從純物理基礎開始做，「說不定20年以後水科學也會有很大的發展」。 

科學解釋：什麼是巨電流變液 

自然界中，液體和固體是有明顯區別的兩種物質形態。水、油等是液體，它們沒有固定的形狀，可以自由流動。鋼鐵、木材、石頭等是固體，它們有固定的形狀。能不能發明一種材料，它既有液體和固體的優點，又可根據需要在兩者間進行轉換呢?這個聽起來似乎異想天開的幻想，已經被科學家實現，即場相應流體，主要有電流變液和磁流變液。 

電流變現象於1947年由美國科學家溫斯洛發現。他將澱粉加在橄欖油中，然後攪拌成一種懸浮液。在試驗中，他意外地發現了一個奇怪的現象，即這種懸浮液在沒有加上電場時，可以像水或油一樣自由流動。可是當一加上電場時，其懸浮液的粘度變稠。當撤消電場時，它又立即回到低粘度的液體狀態。因為這種懸浮液的粘度可以用電場來控制，科學家把它稱為電流變液體。並把這種場誘導下液體粘度可逆變化的物理現象稱為「溫斯洛現象」或「電流變效應」。 

在過去的40年，研究人員對電流變液進行了大量的研究，以期其能夠發展成為工業產品應用於各行各業。然而，這些研究工作最終沒能成功轉變成具有商業價值的產品。電流變液未獲成功的原因可能很多，但最主要的原因是所研究出來的電流變液材料的屈服強度達不到工程材料的應用要求。也就是說，材料的「硬度」達不到固體物質的標準。通常的電流變液屈服強度為3Kpa，最好的材料最大屈服強度也僅為10KPa。除此之外，工業應用受限的其他原因還有液態-固態轉換的時間響應，材料屈服強度對溫度的依賴特性、材料純度對電流表性能的影響、以及與材料需要電源支持等因素。 

溫維佳教授研究的「巨」電流變液(GERF)，改變了上述尷尬局面，不僅屈服應力強度遠遠超出工程應用的要求，其他性能也大幅得到改善，尤其是時間響應等關鍵參數完全達到了工業應用的要求。測試結果表明，巨電流變液具有以下特性，液體-固體間快速轉換響應;超高強度屈服應力;電場操控靈活、控制範圍廣;材料輕便易於各種應用設計等特性。這些優異的特性將會給汽車減震系統，建築減震領域，以及液壓系統，離合器系統等帶來一場革命。目前智能材料實驗室已經可以設計並生產巨電流變液。

温维佳团队拥多项专利

2015-01-10  来源：大公网|

 

【大公报记者周琳北京九日电】“从1992年到现在，我从一个英俊小伙变成了一位‘老’教授。”温维佳笑称，做科学就是要沉下心，现在想来这绝对是值得的。

1992年，温维佳受到美国能源部报告的启发，“能否提高电流变液的强度达到工程应用呢？”当时电流变液之所以未被应用，是由于其强度过低，只有几千帕左右，不能满足工程应用30千帕要求。彼时还是中科院博士的温维佳开始对此感兴趣，他从博士论文做起，实验室的设备、材料都是自己做的。

十载光阴，温维佳团队一直致力于解决材料结构的相容性，最早使用玻璃珠和玻璃粉，做了多次表面处理和改性，却也只有几千帕左右强度。温维佳明白，提高电流变液的强度要在物理机制和材料设计上下功夫。

“中国现在是No.1”

直到2003年，温维佳终于发现了“巨电流变现象”。他找到了合适的硅油为载体，并将介质改为纳米小颗粒后，发现它出现了巨电流变现象，响应时间只要千分之一秒，瞬间就会从液体变成固体，电场越大就越硬。巨电流变液材料的硬度成功达到磁流变液材料的五倍，可以应用高速列车的减震、飞机、机器人等。温维佳的基础研究成果引发了国际的轰动，发表在著名科技杂誌《自然材料》。解决了基础的物理机制，温维佳又?手其应用研究。

温维佳表示，团队目前已拥有多项专利，全球最大的手机和运动品牌製造商也购买了他们的巨电流变液。目前香港合作的公司已经在深圳生产，销往世界各地。

如今，磁流变液处于垄断地位。温维佳说，一个磁力减震器成本很低，但却卖到一千多美元。言谈中，温维佳自信地多次重复电流变液“中国现在是No.1”。
