Abstract:
The composite oxide of La

3 crystal species and grains are characterized by XRD, SEM, EDS and IR measurements.The results show that La

3 grains are spherical, diameter is 19.1mm, under the situation of reunion.At the same time, chitosan/La

3 nanocomposite films has been synthesized by sol-gel method in the solution of chitosan, and its surface, composition changes as well as the particle sizes were analysed by the above analytical method.The results show that there is a strong hydrogen bond between the interaction of chitosan and La

3, the molecular interaction disrupt the original crystal structure of the chitosan.The new molecular array was generated in the complex process between chitosan and La

3.So that good dispersion and compatibility can be formed between the two groups.
