Abstract
The present invention discloses a method of preparing chitin nanofibers. By increasing the saturated moisture content of chitin and instantaneously releasing the pressure under a high temperature and high pressure environment, water within the chitin micro-particles is quickly evaporated and thus generated a high vapor pressure. Consequently, the interaction in chitin fiber is broken, and therefore the chitin nanofibers are obtained.
