Synthesis of Chitin Nano Particles for Preparation of Nano PF Composites

Abstract

Preparation of Phenolic nanocomposites with the help of solvent casting technique was carried out by dispersing the chitin nano particles in water soluble phenol formaldehyde (PF). The nanocomposites were prepared by using water suspended chitin whisker as the reinforced phase and water soluble phenol formaldehyde (PF) as matrix. In the present work, crab shell originated chitin whisker was processed by acid hydrolysis method to prepare the chitin whiskers. The whiskers suspension consists of parallelepiped slender rod shape which can be used for mixing it with any water soluble thermosetting cross linking polymer. The suspension can be mixed with the water soluble aqueous solution of PF so that the suspension quantify for the varying fraction of chitin whisker particles ranging from 1 to 20 percent. Thus the varying fraction, whisker chitin reinforced phenol formaldehyde composites can be prepared by solvent casting process.
