Mercerized natural Cellulose based-solid Polymer Electrolyte

Cellulosic materials derived from three different types of local wood samples (sawmill woods sawdust, Acacia mangium and belian (Euxideroxilon zwagery) were extracted at atmospheric pressure using organosolv method. In an initial stage, the wood samples were delignified using peroxyacetic acid pulpi...
