Abstract

Water miscible hydroxyethyl cellulose(HEC) was modified to increase its fat-solubility by reacting with hexamethyldisilazan. Its synthetic product is trimethylsilyl hydroxyethyl cellulose(TMSHEC). The structure and the surface feature of TMSHEC were characterized by infrared spectra(IR) and scanning election microscope(SEM), the properties were investigated by thermogravimetic analysis(TGA), differential scanning calorimetry(DSC) and mould degradation. The results of TGA and DSC show that the thermal stability and fat-solubility of trimethylsilyl modification cellulose gives rise to a clear improvement. And the mould degradation preliminary experiment proves that the TMSHEC can be biodegraded.
