通过应用石英晶体微天平（QCM）研究了两种不同类型的携带乳糖的聚苯乙烯，聚（对乙烯基苯甲酰胺基-β-乳糖）（PNLA，1）和聚（N-对乙烯基苯甲基内酰胺）（PVLA，2）在聚苯乙烯铸膜以及1-十八烷硫醇和胱胺的自组装单分子层（SAM）上的吸附行为。根据 Langmuir 吸附等温线（表观缔合常数：Ka ≈ 107 M−1），两亲性人造糖复合物聚合物从水溶液中强烈吸附在疏水表面（即聚苯乙烯流延膜和 1-十八烷硫醇 SAM）上。另一方面，它们在胱胺的亲水性 SAM 上吸附很少。聚合物在疏水表面的饱和吸附量比基于闭堆积单层吸附假设计算的饱和吸附量大2~5倍，这表明吸附的聚合物可能呈环链尾构象。 1-十八烷硫醇的 SAM 吸附了两个...
Adsorption behaviors of two different types of lactose-carrying polystyrenes, poly(p-vinylbenzamido-β-lactose) (PNLA, 1) and poly(N-p-vinylbenzyllactonamide) (PVLA, 2), onto cast films of polystyrene and self-assembled monolayers (SAMs) of 1-octadecanethiol and cystamine were investigated by applying a quartz-crystal microbalance (QCM). The amphiphilic artificial glycoconjugate polymers were strongly adsorbed on the hydrophobic surfaces, i.e. a polystyrene cast film and a SAM of 1-octadecanethiol, from their aqueous solution according to the Langmuir adsorption isotherm (the apparent association constant: Ka ≈ 107 M−1). On the other hand, they were adsorbed little on a hydrophilic SAM of cystamine. The saturated adsorption amounts of the polymers on the hydrophobic surfaces were 2—5 times larger than that calculated on the basis of an assumption of closed-packing monolayer adsorption, which suggests that the adsorbed polymers may take a loop-train-tail conformation. A SAM of 1-octadecanethiol adsorbed two...
