FTIR Studies on PMMA-LiNO3 Polymer Electrolyte

Flexible and free standing solid polymer electrolytes are prepared using solution casting technique comprising PMMA and LiNO3. The properties of the polymer system are further improved by adding nanofillers to the polymer matrix. Hence in the present work, the nanofiller Al2O3 is added to PMMA-LiNO3 network. The increase in amorphous nature of the polymer with increase in LiNO3 and Al2O3 is revealed by XRD. The interaction of LiNO3 and Al2O3 with the polymer PMMA is analyzed by FTIR.
