AbstractCHE-0415421Dowben/NebraskaProfessor Dowben at Nebraska and Professor Zhang at Florida International University, along with their coworkers, are investigating the interaction of small molecular species with the surfaces of crystalline polymer materials. With the support of the Analytical and Surface Chemistry Program, they are using a combination of angle resolved thermal desorption, photoelectron diffraction, scanned probe microscopy, and calculational approaches to develop a fundamental understanding of the interaction of molecular species with characterizable polymer surfaces. This information is relevant to technologies ranging from electronic device packaging to sensor systems. The interaction of water and polymer precursor molecules with the surface of semiconducting polymer materials is of fundamental importance to the technologies of electronic materials processing and polymer material growth. With the support of the Analytical and Surface Chemistry Program, Professors Dowben and Zhang are carrying out basic studies of the interaction of these small molecules with the surfaces of well-characterized polymer materials, using a combination of experimental and theoretical probes.

摘要CHE-0415421Dowben/内布拉斯加州内布拉斯加州的道本教授和佛罗里达国际大学的张教授及其同事正在研究小分子物质与结晶聚合物材料表面的相互作用。 在分析和表面化学项目的支持下，他们结合使用角分辨热解吸、光电子衍射、扫描探针显微镜和计算方法，对分子物种与可表征的聚合物表面的相互作用有了基本的了解。 这些信息与从电子设备封装到传感器系统的技术相关。水和聚合物前驱体分子与半导体聚合物材料表面的相互作用对于电子材料加工和聚合物材料生长技术至关重要。 在分析和表面化学项目的支持下，道本和张教授正在结合实验和理论探针，对这些小分子与充分表征的聚合物材料表面的相互作用进行基础研究。
