【 摘 要 】

The surface of cellulose nanocrystals (CNCs) was successfully modified with methacryloyl chloride to create esterified CNCs (M/CNCs). The modification was confirmed by Fourier Transfer Infra-Red Spectroscopy, X-ray Photoelectron Spectroscopy and Zeta potential measurement. With increased surface hydrophobicity, this modified CNC material exhibited improved compatibility with organic network. When used as a filler to be incorporated into a model epoxy resin, TEM results indicated that M/CNCs particles dispersed well in the epoxy network. It was observed that the inclusion of the M/CNCs had an impact upon the heat flow for the curing of the epoxy nanocomposite, leading to an improvement in the storage modulus when tested via dynamic mechanical analysis.
