摘要

Using Brownian dynamics simulations

we find that

for an amphiphilic comb-like copolymer in a selective solvent

there is an optimal total degree of polymerization to form spherical micelles. And when the total degree of polymerization further increases

the spherical micelle will be transformed into a cylindrical micelle.

Abstract

We study the conformation of an amphiphilic comb-like copolymer in a selective solvent by using Brownian dynamics simulations. Our results demonstrate that

there is an optimal total degree of polymerization to form spherical micelles. Only when the total degree of polymerization is less than the optimal total degree of polymerization

a unimolecular spherical micelle can be formed

otherwise

the spherical micelle will be transformed into a cylindrical micelle. When the total degree of polymerization is less than the optimal total degree of polymerization

the radius of gyration and the stretching factor meet an exponential relationship

where the power exponent decreases with the increase of the length of hydrophilic side chains. The fundamental principles uncovered here afford insights for the optimization of molecular design of amphiphilic comb-like copolymers in various applications.
