Preliminary characterization of glycerin, gelatin, propylene glycol, and cellulose based substrates for application in green microelectronics

In this study, the potential of biopolymer-based films for printed electronics was investigated. Three different tapes were prepared using a modified tape casting method, with compositions including glycerin, propylene glycol, and cellulose combined with gelatin. The films were evaluated for their temperature resistance, dielectric properties, and water absorption. The results indicated that the film with propylene glycol exhibited the highest temperature resistance, making it suitable for further application in electronic devices. Additionally, the dielectric properties were stable across the tested frequency range, and further research on biopolymer based biodegradable substrates is recommended for environmentally friendly electronics.
