1. Introduction
Superabsorbent resin (SAR) represents a new type of functional hydrogel with an appropriate degree of cross-linking and polymer network structure. SAR can absorb large volumes of water or aqueous solutions in a relatively short time and retain swollen state even under certain pressure (Ma, Li et al., 2015; Mukerabigwi et al., 2016). Because of these excellent characteristics, SARs are extensively used in many fields, such as agriculture, horticulture, hygienic products, wastewater treatment, drug delivery and coal dewatering, and so on. Generally, raw materials for preparing commercial SARs have almost focused on petrochemical products, such as acrylic acid, acrylamide, polyvinyl alcohol, and acrylonitrile. Though the SARs produced from synthetic polymers with superior price-to-efficiency balance, high production cost and serious environmental problem have been two major concerns for these SARs (Ma, Ran et al., 2015; Mukerabigwi et al., 2015). In this regard, the development of eco-friendly natural-based SARs with low production cost and good biodegradability will be highly desired.To date, various alternatives and strategies have been proposed to prepare low cost and eco-friendly SARs (Bao, Ma, & Sun, 2012; Chen, Zhang, & Li, 2015; Liu, Li et al., 2013; Muhammad et al., 2016). Among them, copolymerization of natural polysaccharides such as starch, cellulose or chitosan with hydrophilic synthetic polymers have been proved to be a popular and applicable method. Nevertheless, the lower swelling ratio and weaker gel strength of these SARs relative to the petro-based products severely restrict their practical application (Bao et al., 2012; Liu, Li et al., 2013; Muhammad et al., 2016; Mukerabigwi et al., 2016; Wang & Wang, 2010). To this end, much effort has been made on developing economic and more effective polysaccharide based hydrogels through different strategies, and much progress has been achieved during past few years (Huang, Liu, Fang, & Zhang, 2013; Ma, Li et al., 2015; Mukerabigwi et al., 2016; Peng et al., 2016). Among them, hybridizing inorganic nanomaterials with SARs have attracted more and more interest owing to their synergistic properties and potential applications in various fields. The incorporation of these nano-fillers can not only reduce production cost, but also improve swelling ability, gel strength, and thermal stability of the corresponding SARs. To date, different additives, such as montmorillonite, kaolin, attapulgite, and vermiculite have been used to fabricate hybrid SARs (Bao, Ma, & Li, 2011; Bao et al., 2012; Zhu et al., 2012).
