Investigation graft polymerization of cyclodextrin derivative on the surface of cellulose by applying plasma technic
Cellulose finds applications in the various fields as composite materials, textiles, drug delivery systems and protective products; in addition, cyclodextrins as a compound to improve these applications, can form inclusion complexes but cannot form direct covalent bonds to the textile materials, so it is important to achieve appropriate methods to anchoring cyclodextrins based on grafting polymeric compounds on the surface modification of the cellulose. In this study, binding of a reactive β-cyclodextrin to cellulose was investigated using chemical, physical and instrumental methods and the mechanism of grafting of reactive cyclodextrin onto the surface of cellulosic fabric was studied. Intended for grafting this compound on the cotton fabric, plasma technique was used to activate the surface to generate free radicals on cellulosic chains. According to the results, the yields of grafting the reactive derivative of β-cyclodextrin onto the surface of cellulosic fabrics increased by applying copolymers of this derivative and an intermediate monomer. In addition, the impact of the graft polymerization of these vinyl monomers on the performance of cotton fabric was evaluated and the results showed that although activation of the surface is attributed to cellulose degradation, the graft copolymerization monomers could be responsible for the compensating increase in its tensile strength and crease recovery in the suitable conditions. Furthermore, investigation the performance of the fabric in different conditions of surface activation and grafting of monomers, increases possibility of explaining the proposed mechanisms.
