| 中文摘要 | the effect of hydrogen bonding (h-bonding) on vesicle structure and its formation of the mixture of ab/bc amphiphilic molecules in a selective solvent for a and c blocks were studied using monte carlo simulation. for the purpose of comparison, h-bonding and covalent bonding were introduced via the two ends of two b blocks. the simulation results indicate that associative interaction of h-bonding (epsilon(hb)) and repulsive interaction between a and c blocks (epsilon(ac)) are the two key factors that determine vesicle structure. four typical vesicles-symmetric, three-layer asymmetric, microphase-separated, and janus vesicles-can be obtained through the adjustment of epsilon(hb) and epsilon(ac). this result is interesting for experimental researchers for controlling vesicle structure and its properties through the introduction of h-bonding. more interestingly, the pathway of vesicle formation also depends on h-bonding. for an h-bonded system, the vesicle is more likely to be formed via diffusion of hydrophilic blocks into the center of spherical micelles. this process is independent of epsilon(ac). however, for a covalently bonded system, the vesicle is more likely to be formed via oblate membrane-closing for higher epsilon(ac) in addition, the vesicle is mote likely to be formed via diffusion of hydrophilic blocks into the center of spherical micelles for lower epsilon(ac) conformational investigation reveals that this h-bonding dependence results from the reversibility of h-bonding. |
