Effect of Impregnated Phenolic Resins on the Cellulose Membrane for Polymeric Insulator

Membranes, 2022
In this study, a cellulose membrane (CM) was chemically treated with phenolic (PF) resin to improve its performance as a polymeric insulator. The CM was prepared from kenaf pulp, and the PF was synthesized from oil palm empty fruit (EFB) fibre.
