evaluation of chitosan quaternary Ammonium Salt modified resin denture base material
International Journal of Biological Macromolecules, 2016Co-Authors: Rong Song, Zhaohua ZhongAbstract:Chitosan quaternary Ammonium Salt displays good antioxidant and antibacterial characteristics and it shows appreciable solubility in water. When added to the traditional denture material to form a resin base, it could promote good oral health by improving the oral environment. In this study, chitosan quaternary Ammonium Salt was added to the denture material following two different methods. After three months of immersion in artificial saliva, the specimens were tested for tensile strength and were scanned by electron microscope. The murine fibroblast cytotoxicity and antibacterial properties were also tested. The result showed no significant differences in the tensile strength and in the proliferation of murine L929 fibroblast cells. The two structures of chitosan quaternary Ammonium Salt-modified denture material had different degrees of corrosion resistance and antimicrobial properties. These results indicate that chitosan quaternary Ammonium Salt-modified resin denture base material has the potential to become a new generation oral denture composite material.

Progress on synthesis of quaternary Ammonium Salt Gemini surfactants
China Surfactant Detergent & Cosmetics, 2015Co-Authors: Dong LAbstract:Structure,properties and applications of the quaternary Ammonium Salt Gemini surfactants were briefed. Synthesis methods for the linear chain type,hydroxyl type,ester radical type,complex group type,ether radical type and the fluorinated type of the quaternary Ammonium Salt Gemini surfactants were emphatically described with their advantages and disadvantages briefly summarized. Performance and properties of various types of quaternary Ammonium Salt Gemini surfactant such as critical micelle concentration( cmc) and surface tension at the cmc( γcmc) as well as their applications in sterilization and metal corrosion prevention et al. were presented. Trends of future development of the quaternary Ammonium Salt Gemini surfactants were prospected.
