Preparation and Mechanical Properties of Composite Chitosan/Nano-Sized SiO_x Film

Wang Ming-li1 Si Fang1 Zhang Yi-ming1 Zhao De-gang2(1.Guizhou Province Key Laboratory of Fermentation Engineering and Bio-Pharmacy,Guizhou University,Guizhou 550003,Guiyang,China;2.Key Laboratory of Green Pesticide and Agricultural Biological Engineering of the Ministry of Education,Guizhou University,Guizhou 550025,Guiyang,China)  
The preparation conditions of composite chitosan/nano-sized SiOx(CTS-SiOx) films were optimized by quadratic-regression rotatable orthogonal experiments,and the films with homogeneous structure were prepared via the casting method,which were then characterized by means of IR,XRD and TEM.The results show that there are a great number of hydrogen bonds between chitosan and the hydroxyls on nano-sized SiOx surface,that the CTS-SiOx film with a chitosan/SiOx/glycerel monostearte mass ratio of 1.98∶0.017∶0.04 has a maximum tensile strength,and that,as compared with the chitosan film,the tensile strength,breaking extensibility and orthogonal-tear strength of the composite film increase respectively by 63.3%,45.4% and 11.6%,while the water permeability decreases by 73.1%.It is thus concluded that the composite film is superior to the film with single component.
