Combined molecular dynamics and dissipative particle dynamics to study of the microstructure of poly(L-lactide)/polyethylene blends.

ABSTRACT

Different type of polymers miscibility has been induced great interest, owing to its relevance to the understanding of processing and performance properties of blends containing different type of polymers. In this article, we investigate the microstructure of poly(L-lactide) (PLLA)/polyethylene (PE) blends. The simulation method is adopted molecular dynamics and dissipative particle dynamics. The results show that the stable microstructures are type of cylinder and lamellae with volume ratio (VPE/VPLLA = 3/7). Furthermore, the lateral compression test is also used to study the stability of microstructure.
