✦ Synopsis

Abstract

Biodegradable lactic‐acid‐based telechelic prepolymers incorporating CNTs were prepared. The products were characterized by FTIR, TGA, DSC, POM, ^1^H and ^13^C NMR, TEM, and FESEM. The results indicated that hydroxy‐terminated telechelic prepolymers were obtained. According to the TGA curves, the initial thermal decomposition temperatures of the prepolymers incorporating carboxylic CNTs were higher than those of the pure prepolymers. Amorphous and crystalline prepolymers incorporating CNTs were obtained, while the spherocrystal morphologies were not changed by the addition of the CNTs. The carboxylic CNTs were coated with PLA polymers after polymerization and well dispersed in the prepolymer matrix.

Silica-coated multi-walled carbon nanotubes (MWCNT@SiO 2 ) were synthesized by a sol-gel method and then incorporated into an epoxy matrix. The less stiff silica intermediate shell on the MWCNTs not only alleviates the modulus mismatch between the stiff MWCNTs and the soft epoxy, but also improves t
