PVA Based Ternary Nanocomposites with Enhanced Properties Prepared by Using a Combination of Rice Starch Nanocrystals and Silver Nanoparticles
- Defence Food Research Laboratory (India)
Ternary nanocomposite films exhibiting better properties were prepared by incorporating two different nanoparticles such as rice starch nanocrystals (RSN) and silver nanoparticles (AgNPs) together in polyvinyl alcohol (PVA) matrix at various concentrations. The morphological evaluation using atomic force microscopy revealed that the particle size of RSN nanoparticles varied from 50 to 125 nm. The nanocomposite films made using these nanoparticles were evaluated for its chemical, mechanical and thermal properties. FTIR spectra of the films revealed some specific vibrational bands of RSN along with the characteristic bands of PVA. The mechanical property analysis of nanocomposite films indicated better tensile strength and elongation properties, which can be attributed to the strong interaction of PVA with RSN and AgNPs. The thermal properties of these films were also evaluated. These ternary nanocomposites exhibited superior mechanical properties, which is very much beneficial as far as the end use applications are concerned.
