摘要：
The surface of conventional carbon nanotube (CNTs) were modified into 4-aminobenzoyl functionalized CNTs (ABCNT) and benzoxazine functionalized CNTs (BZCNT) to improve their surface interaction with bisphenol A based benzoxazine resins (BA-a). Polybenzoxazine (PBZ) composites using these materials were prepared to investigate the effect of different functional groups on the thermal and electrical properties of the composites. The surface modification of CNTs was characterized by Fourier Transform Infrared spectroscopy and thermogravimetric analysis. The PBZ composite with BZCNT showed the better conductivity and thermal properties than the composite with ABCNT due to the chemical bond between BZCNT/BA-a during the curing process which does not exist in the ABCNT/BA-a composite.
