Polymer Structure, Dynamics and Functions on Interfaces

该项目将重点研究液/液界面，即油/水界面（O/W）与气/液界面的界面动力学差异，两亲性聚合物有很强的倾向驻留在O/W界面。其次，在探索固体表面界面动力学的基础上，本研究将详细研究等离子体处理后碳氢化合物聚合物的表面基团迁移。这源于对等离子体诱导的碳氢聚合物蚀刻反应的研究；这个问题与一个重要的应用问题密切相关，即为什么碳氢化合物聚合物薄膜的表面印刷性随着发光放电处理的时间而降低。第三，将制造具有非常大比表面积的多孔聚合物珠，并使其用作生物膜模拟表面。这与设计可作为酶催化剂的生物表面的探索性努力有关。这个项目的第一部分的意义是开发合成更好的表面活性剂的方法，这些表面活性剂应该作为更好的防溢油材料。第二部分阐述了改进塑料片材和薄膜印刷和绘画的方法。第三部分讨论了利用生物催化剂在塑料珠和纳米颗粒上可行的筛选潜在药物的新的和廉价的方法。

This project will focus on how interface dynamics is different on the liquid/liquid interface, namely on the oil/water interface (O/W), contrasted to the gas/liquid interface, with amphiphilic polymers that have strong propensity to reside at O/W interface. Secondly, expanding on the exploration of interface dynamics to solid surfaces, this research will study in detail surface-group migration in hydrocarbon polymers following plasma treatment. This arises from studies of plasma-induced etching reactions on hydrocarbon polymers; the issue is closely associated to an important application problem of why the surface printability of hydrocarbon polymer films diminishes with time upon glow-discharge treatment. Thirdly, porous polymeric beads will be fabricated that have very large specific surface areas and are made to function as biomembrane mimetic surfaces. This is connected to an exploratory effort to design biosurfaces that can act as enzymatic catalysts.%%%The significance of the first part of this project is to develop ways to synthesize better surfactants that should work as better oil-spill containment materials. The second part addresses the ways to improve on the printing and painting on plastic sheets and films. The third part deals with new and inexpensive ways of screening potential drugs by use of biological catalysts mad viable on plastic beads and nanoparticles.
