摘要
Abstract
The design and preparation of functionalized composite structures often require adhesives with both mechanical properties and excellent electrical performance.In this study,multi-walled carbon nanotubes(MWCNT)and surface-aminated multi-walled carbon nanotubes(MWCNT—NH2)were used as reinforcing fillers to investigate the effects of their contents and surface amination on the bonding and microwave absorption properties of epoxy ad-hesives.Results show that MWCNT significantly regulate the adhesive properties:with increasing content,the bond-ing strength exhibits a trend of first increasing and then decreasing,while the microwave absorption performance gradually enhances.Surface amination modification improves the interfacial compatibility between MWCNT—NH2 and the epoxy matrix,thereby significantly optimizing the bonding performance.However,the introduction of surface functional groups alters the electronic structure of MWCNT—NH2 and disrupts the conductive network,re-sulting in a substantial decline in the microwave absorption performance of the MWCNT—NH2-modified adhesive compared to that of the unaminated MWCNT system.关键词
