摘要

采用正电子湮没技术研究了端羟基液体丁腈（HTBN）增韧环氧树脂（EP）体系的自由体积特性

证实了HTBN橡胶相与EP基体相界面过渡区域自由体积尺寸的大小和浓度与增韧效果相关。当HTBN的浓度为5%时

增韧效果最佳

相尺寸小

相界面过渡区域自由体积空穴尺寸与EP自身分子间自由体积空穴尺寸相当

增韧效果好;当HTBN的含量继续增加

分散相尺寸增大

过渡区域自由体积尺寸增加较快

增韧效果弱化。

Abstract

The free volume properties of epoxy/hydroxyl terminated butyl nitrile rubber(EP/HTBN) have been studied by means of positron annihilation technique.The toughness effect is found to be correlated with the content of HTBN and the free volume properties of the EP/HTBN interfaces.When the content of HTBN component is 5%

the free volume size in the interface is close to that of EP

and the toughness effect is strong.But with further addition of HTBN

holes with big size free volume are formed in the interface

and the toughness effect is limited.
