Chitin nanofibers were prepared from dry chitin powder by nanofibrillation using a Star Burst instrument employing a high-pressure water jet system. FE-SEM micrographs showed that the nanofibers became thinner as the number of Star Burst passes increased. Fibrillation in an acidic condition made the chitin fibers thinner than those in a neutral condition. The transmittance spectra of chitin nanofiber/acrylic resin composites led us to the same conclusion. In addition, chitin nanofibers prepared by treatment consisting of five Star Burst passes in the neutral condition were thinner than the previously reported nanofibers. X-ray diffraction profiles showed that the Star Burst system did not damage the chitin nanofibers and did not reduce their crystallinity.
