【摘要】 目的　建立一种形成高分子自组装膜的新方法。方法　先使硅表面硅烷化 ,再通过化学方法定向聚合形成高分子自组装膜。并利用原子力显微镜 (AFM) ,接触角测定 ,X -射线光电子光谱 (XPS)技术研究了该膜的表面形态。结果　该方法可以在功能化的硅表面形成结构均一的高分子自组装膜。结论　可以通过控制聚合过程而得到纳米厚度的聚合物膜 ,消除了吸附方法所带来的膜不均匀性 ,膜厚度的不可控制性。更多还原

【Abstract】 Objective To set up a new method of forming macromolecule self-assembled monolayers. Methods First,octadecyltrichlorosilane was fixed on functioned silicon surface,then macromolecule self-assembled monolayers were formed by chem i cal polymerization and studied with AFM and XPS.The contact angle of water at v arious substrates surface was determined. Results This method may form a homogeneous macromolecule self-a ssembled monolayer on silicon surface. Conclusion Through controlling the polymerization a polymer mon ogeneity can fashion.The monogeneity is homogeneous and controllable unlike adso rbent monogeneous.更多还原
