Abstract
Aiming at the difficult problem of solving the conformation statistics of complex polymers,this study presents a novel and concise conformation statistics theoretical approach based on Monte Carlo and Neural Network method.This method offers a new research idea for in-vestigating the conformation statistics of complex polymers,characterized by its simplicity and practicality.It can be applied to more complex topological structure,more higher degree of freedom polymer systems with higher dimensions,theory research on dynamic self-consistent field theory and polymer field theory,as well as the analysis of scattering experimental data.The conformation statistics of complex polymers deter-mine the structure and response properties of the system.Using the new method proposed in this study,taking the semiflexible ring diblock copolymer as an example,Monte Carlo simulation is used to sample this ring conformation to construct the dataset of polymer.The structure fac-tor describing conformation statistics are expressed as continuous functions of structure parameters by neural network supervised learning.This is the innovation of this work.As an application,the structure factors represented by neural networks were introduced into the random phase ap-proximation theory to study the microphase separation of semiflexible ring diblock copolymers.The influence of the ring's topological proper-ties on the phase transition behavior was pointed out.
