Abstract
Bacterial cellulose whisker BCW reinforced carboxylated acrylonitrilebutadiene rubber xNBR vulcanizates were fabricated by mixing BCW suspension with xNBR latex followed by coagulating and vulcanization The BCW prepared from acid hydrolysis of bacterial cellulose has as rodlike nanofiber structure according to transmission electron microscopy BCW maintained its crystal structure in BCW/xNBR vulcanizates as confirmed by Xray diffraction The incorporation of BCW improved the curing rate of xNBR Compared with unfilled xNBR the tensile strength Young’s modulus and tear strength of BCW/xNBR vulcanizates were increased considerably by 320 150 and 150 respectivelyThe storage modulus E′ and glass transition temperature T g also increased because of the addition of BCW
