U.S.-Czech Materials Research on Tailored Polymer/Inorganic Solid Interfaces

由宾夕法尼亚大学的Russell Composto博士和捷克科学院大分子化学研究所的peter Vlcek博士共同发起的这项美国-捷克研究项目的目的是合成新型聚合物材料，以研究聚合物在聚合物/固体界面上的吸附。为了做到这一点，研究人员将使用阴离子活聚合和基团转移聚合技术来制备嵌段共聚物和末端功能化聚合物，这些聚合物可以结合到氧化物表面。这些特殊聚合物将与基体聚合物混合，并在无机基板上纺铸。测定了吸附物的组成、吸附量、接枝密度和吸附强度。研究结果将有助于我们了解聚合物粘附的基本知识，并可能与涂料行业的技术问题相关。该材料研究项目通过使美国和东欧的专家在共同感兴趣和能力强的领域结合互补的人才和共享研究资源，实现了推进科学知识的计划目标。

9417523 Composto The purpose of this U.S.-Czech research project between Dr. Russell Composto of the University of Pennsylvania and Dr. Petr Vlcek of Czech Academy of Sciences' Institute of Macromolecular Chemistry is to synthesize novel polymeric materials to study polymer adsorption at the polymer/solid interface. To do this, the researchers will use anionic-living and group-transfer polymerization techniques to prepare block copolymers and end- functionalized polymers which bind to oxide surfaces. These specialty polymers will be blended with a matrix polymer and spun-cast on an inorganic substrate. The composition profile, amount absorbed, grafting density of the adsorbed species, and the strength of adsorption will be measured. Results are expected to contribute to our basic knowledge of polymer adhesion and may have relevance to technological problems in the coatings industry. This project in materials research fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.
