摘要: A bead-and-spring model has been used to simulate the behavior of thermoresponsive asymmetric diblock amphiphilic copolymers with aid Monte Carlo simulations. The alteration thermodynamic conditions was mimicked by using a Lennard-Jones potential, which related measured temperatures comparison experimental data for aqueous solutions two sets copolymers, namely methoxypoly(ethylene glycol)-block-poly(N-isopropylacrylamide), one different lengths hydrophilic block (MPEGn-b-PNIPAAM71) and varying hydrophobic (MPEG57-b-PNIPAAMm). influence length both on size conformation single molecules at various studied means temperature-induced contraction copolymer entities is only modestly affected changing block, whereas MPEG57-b-PNIPAAMm ...
