Summary:Dielectric polymer like pure poly methyl methacrylate (PMMA) and its composites with nanoparticles (NPs) are interesting for industrial application such as solar cell, energy storage devices etc. Reinforcement of PMMA enhances its own properties and promotes unique applications in different areas. On the other hand, Co3O4 NPs are semiconducting in nature and find versatile applications in the optoelectronics field. When Co3O4 NPs-PMMA composites are formed, the properties of PMMA get modified. Therefore, before realizing the applications, it is necessary to understand the basic properties of this composite. With this motivation we have synthesized pure PMMA and Co3O4 NPs-PMMA composite self-standing films via solution casting method and studied their dielectric properties in terms of variation in dielectric constant (ε’) and Dielectric loss (ε’’) as a function of filler particles (Co3O4 NPs) concentration. To investigate the modification in bonding behavior of PMMA in presence of metal oxide nanoparticles, Fourier transform infrared (FTIR) spectroscopy was employed, which showed that beyond 1 wt% of NPs concentration, PMMA bonds are broken, indicating a strong modification in basic PMMA properties. The result presented here would be helpful in studying the dielectric properties of reinforced polymers in future.
