In this paper, we put forward (i) a unified workflow to develop chemical-drawing-to-atomistic models for SCP chains and (ii) an accelerated approach to obtain electronic structure properties, which takes into account the inter-molecular interactions and electrostatic environment of the surrounding chains. The accuracy of the QC/MD method is evaluated by comparing the morphological characteristics (e.g., torsion angle distribution, end-to-end distance, radial distribution function,) and electronic properties (e.g., DOS and DOS-driven properties), calculated for polymer chains sampled from (conventionally) equilibrated polymer melt models and those constructed by the faster alternative approach.
