Preparation and Properties of Tourmaline/Chitosan Composite Powder

Abstract

Chitosan has good biocompatibility and physiological activity, tourmaline possesses characteristics of generation of anion, reduction of water molecular beam and emission of far infrared radiation, so the two composite materials will hopefully possesses the two excellent properties, thus show good application prospect in the biomedical and cosmetic field. Experiment utilized chitosan as wrapped base material, adopt method of suspension solution compound precipitation to manufacture chitosan/tourmaline compound powder, using XRD, SEM, IR and other means to represent powders prepared, and the experimental results show that the synthetic compound powder with irregular granular, chitosan wrapped tourmaline well, the composite of tourmaline and chitosan is physical composite, with the increment of tourmaline , the degree of crystallization of chitosan in compound powder weaken, the composite powder has good absorptive and preservative liquid ability.
