Functionalization of unzipped carbon nanotube via in situ polymerization for mechanical reinforcement of polymer

摘要: Multiwalled carbon nanotubes (MWNTs) have been widely used as mechanical reinforcement agents during the past decades. However, complete achievement of enhancement has greatly impeded by their limited available interfacial area (AIA) and weak adhesion force with polymer matrix. In this paper, we use unzipped MWNTs (uCNTs) a precursor to fabricate poly(methyl methacrylate) (PMMA) functionalized uCNTs (uCNTs-P) via in situ free radical polymerization. Fourier transform infrared (FTIR), X-ray powder diffraction (XRD), photoelectron spectra (XPS), Raman, thermogravimetric analysis (TGA) are applied characterize structure resultant uCNTs-P. The testing composite films indicated that uCNTs-P were more effective than improving tensile strength Young's modulus. This excellent is attributed uCNTs-P's highly strong interlocking study will guide design preparation high-performance composites.
