This study demonstrates reliable resistive switching behavior in PVA-cellulose composites, suggesting a viable option for flexible memory applications.
Flexible and sustainable materials are becoming increasingly important for next-generation electronic devices. This study examines the resistive switching behavior of a polyvinyl alcohol (PVA)–cellulose composite and its potential application in resistive switching memory. Cellulose fibers were extracted from the lotus petiole and purified with chemical agents. The composite of PVA and cellulose was dropped as an insulator layer in the capacitor-like structure of Ag/PVA–Cellulose/FTO. Structural analysis confirms strong interactions between PVA and cellulose, which contribute to improved material stability and film formation. Electrical measurements demonstrate reliable bipolar resistive switching at 1 V, while endurance tests reveal stable performance over 50 switching cycles. These results highlight the advantages of combining cellulose with PVA, offering a promising approach for developing flexible memory devices and environmentally friendly electronic materials.
