Research paper thumbnail of Synthesis and analysis of flexible biodegradable graphite composite for microwave applications

2ND INTERNATIONAL CONFERENCE ON EMERGING SMART MATERIALS IN APPLIED CHEMISTRY (ESMAC-2021): ESMAC-2021

Different concentration of graphite (0.5, 1, and 1.5 wt. %) were mixed with PVA for understanding the effect of graphite in PVA matrix. Solvent casting method was employed for fabricating the polymeric composite. The chemical characterization confirmed the interaction of graphite in PVA matrix. Dielectric constant and electromagnetic characterization (reflection coefficient (S11), and transmission coefficient (S12) were analyzed at X-Band. The maximum reflection coefficient of-19.6 dB at 9.3 GHz and the maximum transmission value was-9.96 dB at 10.65 GHz were recorded. The microwave interaction of developed composite proves it be a potential biodegradable composite for electronic applications.

2ND INTERNATIONAL CONFERENCE ON EMERGING SMART MATERIALS IN APPLIED CHEMISTRY (ESMAC-2021): ESMAC-2021

In this study, Zinc oxide (ZnO) thin films was fabricated using poly-vinyl alcohol (PVA).Vector N... more In this study, Zinc oxide (ZnO) thin films was fabricated using poly-vinyl alcohol (PVA).Vector Network Analyser was employed to comprehends the electromagnetic effect of ZnO in PVA in X-band frequency range (9-11.5GHz). PVA/ZnO films having different concentration of ZnO (1%, 2% and 4%) were made using solvent casting technique. Microwave and material characterizations of thin film were done for understanding the dielectrics and scattering parameters of the material. Dielectric constant varies from 0.98 to 1, for all ZnO concentration in the matrix. Also, the scattering parameters showed the dominant electromagnetic reflection properties of the material.
