摘要: The formation and physical properties of solid-supported polymer bilayers (SPBs) on an adhesive substrate have been explored by dissipative particle dynamics simulations. A SPB is developed by the adsorption of vesicles formed by diblock copolymers in a selective solvent. The adsorbed vesicle can remain intact or become ruptured into a SPB, depending on the interaction between solvophobic blocks and solvent and the interaction between solvophilic blocks and the substrate. The morphological phase diagram of adsorbed vesicles is acquired. The influence of polymer adhesion strength and solvophobicity on the geometrical and mechanical properties of a SPB is systematically studied as well. It is found that vesicular disruption is easily triggered for strong adhesion strength. Moreover, for strong adhesion strength and weak solvophobicity, the fluctuation of membrane height is impeded while the area of fluctuation is enhanced. The dynamic disintegration process from an adsorbed vesicle to the formation of a polymer bilayer. 其他題名: Soft Matter 出版者: England 出版日期: 2016-01-01 出處: Soft matter, 2016-01, Vol.12 (3), p.6442-645 識別號: ISSN: 1744-683X 識別號: EISSN: 1744-6848 識別號: DOI: 10.1039/c6sm00741d 識別號: PMID: 27418114
