摘要

This study constructed PA6/OMMT/mPOE/PTFE nanocomposites using PA6 as the substrate. The TB structure significantly improves the toughness and gas barrier performance of the material.

Abstract

Polycaprolactam (PA6) is an important engineering plastic known for its excellent strength and processability

making it widely applicable in the automotive and transportation industries. Previous studies have demonstrated that incorporating a small amount of organic-modified montmorillonite (OMMT) can significantly enhance the gas barrier properties of PA6. Based on PA6/OMMT

this study further introduced maleic anhydride-grafted ethylene-octyl copolymer (mPOE) and polytetrafluoroethylene (PTFE). Morphological characterization revealed the successful manipulation of the microstructure within this toughening system

revealing a distinctive tassel bundle morphology in the ternary blend of PA6/mPOE/PTFE. in the quaternary PA6/OMMT/mPOE/PTFE system

scanning electron microscopy (SEM) analysis demonstrated that the special “tassel bundle (TB)” morphology could induce an ordered arrangement of OMMT nanosheets

leading to synergistic improvements in both toughness and gas barrier performance. These findings offer promising potential for applications requiring simultaneously high gas barrier properties and enhanced toughness

particularly in hydrogen storage tanks and related industrial fields.
