Title:
Impact of swift heavy ions irradiation on the physico-chemical properties of IPNs
Abstract:

Superabsorbent hydrogels are three-dimensional cross-linked network of linear or branched polymers with high efficacy for absorbing either water or biological fluids. The ability to absorb aqueous fluids is due to the presence of certain functional groups like –NH2, -COOH and –OH. Cross-linked hydrogels based on natural materials, such as cellulose, starch, dextran, gum and chitosan, because of their easy availability, low production cost, non-toxicity and biodegradability have attracted great attention. It has been widely accepted that natural polymers have better biocompatibility and are non-toxic than most synthetic one. Such materials have been applied in controlled drug delivery devices, biosensors, tissue engineering, contact lenses, soil conditioning, removal of heavy metal ions and dyes. 

Gums are natural polysaccharides and are known to be potential antioxidants. They are mainly used as food additives. They have excellent properties such as high solubility, pH stability, non-toxicity and gelling characteristics. Research efforts in this area are directed towards the grafting and network formation of Gums with different vinyl monomers using cross-linkers under variable synthetic conditions so that they could be applied for varied applications. 

Till date lot of methods have been applied for the synthesis and modifications of cross-linked materials with improved properties suitable for different applications. It is well known that ion beam irradiation can play a crucial role to synthesize, modify, crosslink or degrade polymeric materials. High energetic heavy ions irradiation on polymer film induces significant changes like chain scission, cross-linking, structural changes, amorphization and degradation in bulk. Various researchers reported the effects of low and heavy ion irradiation on the properties of polymeric materials and observed significant improvement in optical, electrical, chemical, thermal and dielectric properties. Moreover, modifications induced in the materials mainly depend on the structure, the ion beam parameters like energy, linear energy transfer, fluence, mass, charge and the nature of the target material. Ion-beam irradiation is a useful technique for improving the surface properties of biodegradable polymers without missing the bulk properties. Therefore, a considerable interest has been grown to study the effects of SHIs irradiation on the properties of synthesized semi-IPNs and IPNs. The present work deals with the preparation of semi-IPNs and IPNs and impact of SHI like O7+ and Ni9+ irradiation on optical, chemical, structural, morphological and thermal properties alongwith impact on different applications. The results have been discussed on the basis of Linear Energy Transfer (LET) of the ions.
