| Research Abstract |
Microfibril-cellulose and bacterial cellulose consist of nano-level width fibers, therefore, they are called cellulose nano-fiber. In this study bacterial cellulose fiber was selected and ultra-thin sheet-making was investigated. At the sheet making, chitin powder was added as filler. Chitin addition is hopeful for improving opacity of cellulose sheets. N-chlorinated bacterial cellulose was prepared for increasing sheet strength. N-chlorinated bacterial cellulose was prepared by the three step reaction: cyanoethylation, carbamoylethylation and N-chlorination. Each reaction readily proceeded. The dry tensile index of N-chlorinated BC sheet (10 micrometers thickness) was about 1.7 times higher than that of a BC sheet, and the wet tensile strength was about 3.6 times higher. By N-chlorination of BC, I could prepare sheets down to a thickness of 3 micrometers. Opacity of chitin-powder added BC sheet was increased about 10 % comparing to untreated BC sheet.
