氢键交联型自修复超强韧聚硅氧烷的制备与性能研究
Preparation and Performance of Hydrogen-Bond Crosslinked Self-Healing Ultra-Tough Polysiloxane
摘要
Abstract
This study developed a polysiloxane elastomer system based on dynamic hydrogen bond crosslinking.By incorporating acylaminourea groups,a multiple reversible non-covalent network was formed,successfully developing PDMS2-ADx,a material with both self-healing capability(self-healing efficiency up to 90%)and ultrahigh stretchability(560%elongation at break).Mechanical tests demonstrated that tuning hydrogen bond density significantly optimized material performance(1.9 MPa tensile strength).When applied as a flexible strain sensor,the material exhibited stable signal response within deformation ranges.This work establishes a novel molecular design paradigm for synergistic optimization of"mechanical strength-self-healing"in high-performance elastomers,showing promising potential in wearable electronics and self-healing soft materials.关键词
