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.

该项目将侧重于如何界面动力学是不同的液体/液体界面上，即在油/水界面（O/W），对比气/液界面，与两亲性聚合物，有很强的倾向，驻留在O/W界面。 其次，将界面动力学的探索扩展到固体表面，本研究将详细研究等离子体处理后烃类聚合物中表面基团的迁移。 这源于对烃聚合物的等离子体诱导的蚀刻反应的研究;该问题与为什么烃聚合物膜的表面可印刷性在辉光放电处理后随着时间而减小的重要应用问题密切相关。 第三，将制造具有非常大的比表面积的多孔聚合物珠，并使其用作生物膜模拟表面。 这与设计可用作酶催化剂的生物表面的探索性努力有关。%该项目第一部分的意义在于开发合成更好的表面活性剂的方法，这些表面活性剂应作为更好的溢油遏制材料。 第二部分论述了提高塑料薄膜印刷质量的途径。 第三部分涉及新的和廉价的方法，筛选潜在的药物，通过使用生物催化剂，可在塑料珠和纳米粒子。
