摘要

Abstract

With the growing demand for advanced materials with excellent gas barrier properties

mechanical performance

and processability

the development of high-performance rubber-plastic composites has become increasingly crucial. In this study

a series of rubber-plastic composites of high-density polyethylene (HDPE) and

trans

-butadiene-

-isoprene rubber (TBIR) with different phase structures were designed

via

two processing routes: dynamic vulcanization (DV) and conventional vulcanization (CV). The dynamic vulcanization process effectively induces phase inversion between the rubber and plastic phases

forming a typical "sea-island" structure

where HDPE serves as the continuous phase and TBIR as the dispersed phase. With an increase in the HDPE content

the size of the dispersed TBIR particles became more uniform and finer

which contributed to the comprehensive performance enhancement of the composites. This unique microstructure enables the composites to maintain a relatively high tensile strength and modulus

while significantly improving the gas barrier performance. Specifically

the permeability coefficients of N

and CO

decrease remarkably with an increase in HDPE

gradually approaching those of pure HDPE. In contrast

the conventionally vulcanized samples maintained a rubber-continuous phase at low HDPE contents

leading to only limited improvement in the gas barrier properties. This study confirms the feasibility of regulating the microstructure of HDPE/TBIR composites through dynamic vulcanization

which provides a theoretical and experimental basis for the development of high-performance gas-barrier materials and their potential applications in various barrier-related fields.
