Abstract

Polymer network composites are thermoplastic or thermosetting polymers strengthened with natural or inorganic fillers. In the progressing years, basic strands are used as bracing administrators to make standard fiber reinforced polymer composites rather than designed fibers which are from oil sources. An extensive part of the composites of hydrophilic regular strands with hydrophobic designed polymers encounter the evil impacts of the nonattendance of strong interfacial bond between them. To conquer this trouble, the present examination expected to mix a characteristic fiber with biopolymer to create an all-green Biocomposite film. For this reason, chitosan a cheap, biodegradable and biocompatible biopolymer was been mixed banana filaments. The crude filaments were pre-treated by mercerization (5% of NaOH arrangement) The after effects of pre-medications demonstrated that the expulsion of lignin and hemicelluloses materials from the strands affected decline in hydrophilicity, Increase in surface smoothness, in this way rendering the filaments appropriate to be Blended with chitosan. Crude and pre-treated strands were blended with chitosan and cast in to films. The impacts of pre-treatment of fibers, rate structures of the mixes film were assessed by utilizing tensile test, XRD, SEM, water ingestion and biodegradable test. In light of the above outcomes chitosan banana films arranged in the present examination can be proposed as materials reasonable to be produced for packaging industry and tissue designing applications.
