表面的移动性、灵活性和交联度 高分子区是与附着力相关的重要参数 科学、光致抗蚀剂和生物医学聚合物性能。西姆斯是 用于从自组装中提取移动性信息 基于烷基硫醇的单分子膜(SAM)吸附在金上。作为混合的 长度的自组装膜可以表现出不同程度的表面迁移率 用C12正构烷基硫醇和C18正构烷基硫醇在金上制备 以100%C12，80%C12，60%C12，40%C12，20%C12， 和0%C12正在研究中。除了移动性信息之外， 开发一个有用的静态SIMS排放模型所需的数据 通过这一研究计划，可以获得聚合物碎片。

The mobility, flexibility, and crosslink density of the surface zone of polymers are important parameters relevant to adhesion science, photoresists, and biomedical polymer performance. SIMS is being employed to extract mobility information from self-assembled monolayers (SAMs) based upon alkane thiols adsorbed to gold. As mixed length SAMs may exhibit varying degrees of surface mobility, SAMs fabricated on gold with C12 n-alkane thiol and C18 n-alkane thiol prepared at mole percents of 100%C12, 80%C12, 60%C12, 40%C12, 20%C12, and 0%C12 are being studied. In addition to the mobility information, data needed to develop a useful model for static SIMS emission of polymer fragments might be obtained through this research program.
