chlorodecyldimethylsilane or chlorodimethyloctadecylsilane, and their capability as model systems for organic templating was evaluated. The structure of the resulting binary mixed SAMs was analyzed by water contact angle measurements, null ellipsometry, and X-ray reflectivity (XRR) in combination with theoretical modeling by a multidimensional Parratt algorithm and AFM. The composition dependence of film thickness

硅表面上的自组装行为。
联苯硅烷4(T m -C n)及其前体3(T m -C n)的介晶性质通过差示扫描量热法(
DSC),偏振光学显微镜(POM)和X射线衍射确定。从小角X射线散射(
SAXS)方案,可以推断出优先盘状片状中间相,而广角X射线散射(WAXS)突出了烷基侧链的液体状特征。为了将这些整体结构性质转移到薄膜上,通过从溶液中吸附获得自组装单分子膜(S
AMs),并通过
水接触角测量,零椭偏法和原子力显微镜(A
