Description
Summary:Bacterial cellulose (BC) fibers which are produced by acetic acid bacteria and are a well-known biomass resource were used to synthesize carbon nanofibers (CNFs) as a filler of C/C composites. The iodine treatment of BC resulted in large improvements in carbonization yield and surface textural-changes during CNF preparation in comparison with raw BC. The C/C composites were prepared from furan resin with BC fibers and CNFs derived from raw or iodine-treated BC, and their wear properties were examined. Composites filled with 0.5 wtX or more of CNFs obtained from iodine-treated BC showed a lower relative wear volume than C/C composites with BC fiber or CNFs from raw BC. Taking into account the densities, electrical conductivities and SEM observations of the C/C composites with different fillers, it is suggested that the higher wear resistance is related to the unique surface texture of CNFs obtained from iodine-treated BC which improved interface adhesion between the fibers and the matrix.
