Abstract
This paper concerned nanocrystalline cellulose(NCC)’s isolation from microcrystalline cellulose(MCC) by sulfuric acid hydrolysis, meanwhile centrifuging, ultrasonic treatment and freeze-drying were carried out afterwards. It covered the effect of reaction conditions on the yield of NCC. It indicated that hydrolysis time was the factor that matters most and it was possible to obtain the largest yield with hydrolysis time being 108min, hydrolysis temperature being 43oC and sulfuric acid concentration being 33%. It also investigated the microcosmic morphology of NCC by Transmission Electronic Microscopy(TEM). MCC and NCC’s thermal properties were studied further.
