Cordierite and Li2CuPO4 synthesis were endeavored using the solid-phase reaction or wet chemistry methods. Excellent microencapsulation of the [Erythritol]-HDPE composite was demonstrated, while the [Luxolina]-TEOS system exposes low affinity to the core-shell structure. The thermal properties of electroceramics and PCM (phase change material) composite were characterized by the heating rate index (fh), heating lag factor (jh), and temperature stability time (ts).

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.
