“…The formation of methylene bridges is a result of the condensation of methylol groups during the resinification process. The commercial PF resin showed a peak at around 1267 cm −1 , which represents C-O-C linkage [22]; meanwhile, in synthesized PF, the peak at 1221 cm −1 belongs to asymmetric stretches of C-C-OH [23]. The aliphatic hydroxyl was represented by peaks at around 1020 cm −1 [24].…”

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. Four different concentrations of synthesized PF resin (5, 10, 15, and 20 wt.%) were impregnated under wet or dry conditions. Thermal analysis of the phenolic cellulose membrane (PCM) showed that the samples had good chemical interaction and compatibility. The PF uptake in the wet phenolic cellulose membrane (PCMW) was higher than in the dry phenolic cellulose membrane (PCMD). During the PF uptake, the CM underwent solvent exchange and absorption in wet and dry membranes, respectively. This difference also affected the crosslinking of PCM samples via the formation of methylene bridges. Due to the PF treatment, the PCM showed lower water absorption than CM. The PF concentrations also affect the surface roughness and electrical properties of PCM samples. These findings prove that PCM can be used as a renewable and green polymer electrical insulator.

“…Malaysian National Biomass Strategy 2020 (Agensi Inovasi Malaysia 2016) has highlighted many plans to enhance the utilisation of this biomass into value added products. Therefore, to ensure the EFB biomass can be fully utilised, various products have been produced using different techniques such as cellulose hydrogel from dissolving pulp using acid and thermal hydrolysis (Gan et al 2015), levulinic acid from acid hydrolysis , anionic and cationic adsorbents via chemical modification (Sajab et al 2015) and bio-based resin from liquefaction and resinification (Amran et al 2013).…”
