Acetylated lignin from oil palm empty fruit bunches and its electrospun nanofibres with PVA: Potential carbon fibre precursor.

The electrospinning of acetylated lignin/polyvinyl alcohol (PVA) nanofibres was carried out to expand the application of lignin materials obtained from oil palm empty fruit bunches (OPEFB). Lignin was isolated by the steam explosion method and subsequently precipitated using HSO. Acetylated lignin was produced by mixing acetic anhydride and pyridine at a 2:1 v/v ratio.

Antimicrobial and antihemolytic properties of a CNF/AgNP-chitosan film: A potential wound dressing material.

Cellulose nanofibers (CNFs), chitosan, and silver nanoparticles (AgNPs) are widely used to enhance the active functions and antibacterial properties of wound dressings. This study was conducted to prepare CNF/AgNP-chitosan using a straight incorporation method and to assess its antimicrobial activity. CNFs were isolated from oil palm empty fruit bunches (OPEFBs) using the pulping method and acid hydrolysis.

Isolation and Characterisation of Cellulose Nanofibre and Lignin from Oil Palm Empty Fruit Bunches.

A study on isolation and characterisation of cellulose nanofibre (CNF) and lignin was conducted to expand the application of CNF and lignin from oil palm biomass. CNF was extracted by steam explosion and the by-product was precipitated to obtain lignin by using the soda-pulping method. The concentrations of NaOH used for CNF by-product precipitation were 2%, 4%, and 6%.
