Abstract

Currently, plant-derived polysaccharides are extensively utilized in various industrial purposes by reason of excellent biodegradability, sustainable production, economical processing cost, and high abundances. But, plant polysaccharides fail to meet some necessary requirements like solubility, colloidal and mechanical properties, degradability, etc. The industrial utility of these can be improved through graft copolymerization. Graft copolymerization of plant polysaccharides facilitates the introduction of functional groups onto the polysaccharide backbone to enhance intrinsic properties like rheological properties, hydrophilicity, polymer charges, molecular chains' aggregation, and complexing capability. By virtue of the favorable intrinsic properties, plant polysaccharide-g-copolymer(s) have been employed as flocculants, decolorizing agents, thickeners, adsorbents, drug delivery carriers, electrical conductors, etc., in industrial fields like chemical engineering, dyeing, biomaterials, drug delivery, foods, agricultural, paper-making, wastewater treatment, etc. The current chapter summarizes previously reported some plant polysaccharide-g-copolymer(s) with a brief description of concept and methods of graft copolymerization following application domains.

1. Introduction

The usage of naturally occurring materials is extremely enhanced in almost all spheres of human lives during the past few decades (Lloyd et al., 1998; Hasnain et al., 2010; Pal and Mitra, 2010; Nayak and Pal, 2012; Pal et al., 2012). Currently, synthetic products are being replaced by natural materials due to their excellent biodegradability, sustainable production, low cost, high abundances, etc. (Nayak et al., 2013a,b). Plant polysaccharides are naturally occurring carbohydrate macromolecules, which are extracted from different plant parts like fruits, rhizomes, leaves, pods, seeds, peels, etc. (Nayak and Pal, 2015). They are physicochemically as well as structurally diverse, encompassing a variety of backbones/functional groups (Kaur et al., 2012b; Nayak et al., 2013c; Nayak et al., 2015). Like other natural products, plant polysaccharides also exhibit several advantages (Avachat et al., 2011; Nayak et al., 2012; Pal and Nayak, 2015), which eventually make possible for different industrial uses like food, confectionary, biomedical, pharmaceutical, cosmeceutical, chemical engineering, paper-making, and so on (Nayak and Pal, 2012; Prajapati et al., 2013). However, most of the plant polysaccharides in their native form demonstrate unsatisfactory outcomes due to their uncontrolled rate of hydration, variable aqueous solubility, pH, rheological alterations during storage, pH responsive swelling, possibilities of contaminations by microbial attack, etc. (Nayak and Pal, 2015; Nayak, 2016).
Many research laboratories have made great headway to modify plant polysaccharides chemically by introduction of various functional groups (viz. –COOH, –NH2, –SH, –NH4+Cl, –SO32, –OC2H5, –OCH3, –CH
CH2, –C
O(NH2, etc.)) (Wang and Wang, 2013; Thakur and Thakur, 2014, 2015) to inculcate desired functional properties. A wide variety of structural compositions of plant polysaccharides allow appropriately tailoring their structures (Kaur et al., 2012a,b; Manchanda et al., 2014) through various chemical reactions such as cross-linking (Maiti et al., 2011; Sarmah et al., 2011...
