Oxidation of Natural Fiber

Cellulose-based natural fiber can be oxidized using oxidizing agent with acidic catalyst. Oxidation reactions applied to cellulose in fiber for chemical modifications [43]. Oxidation reactions occur on cellulose selectively at particular position. The reaction of sodium metaperiodate with cellulose in wood fiber in the presence of sulfuric acid catalyst at 120°C and 85 KPa pressure yielded the oxidized product. Sodium metaperiodate reacts with hydroxyl groups of cellulose and produce 2,3-dialdehyde cellulose which improved the physical and mechanical properties of polymer composites [44]. [Pg.321]

Chemical modification with suitable chemicals and innovative technology provides a noble and facile route for the development of intrinsic negative properties of cellulose-based composites materials. Although, the chemical treatments sometimes improved the certain properties composites, however, negative effect also observed. Alkali treatment improved adhesion and compatibility considerably among all conventional [Pg.321]
