Abstract

The method for the creation of surface-grafting polymeric materials is gaining recognition because it makes it possible to create novel materials from wellknown, commercially available polymers with desirable bulk properties like elasticity, permeability, and thermal stability, combined with advantageous, newly tailored surface properties like adhesion, biomimicry, and biocompatibility. Since it produces radicals on most substrates, ionizing radiation is one of the most effective techniques for creating graft copolymers. This process involves the use of radiation, such as UV, plasma, Electron Beam (EB), and γ-rays, to modify polymer substrates. The development of RIGG in pharmaceuticals focuses on the covalent immobilization of biocides to various polymer surfaces. Grafting can now be done under control to produce surfaces with specific and well-defined features. The application of radiation has entered a new era of grafting with the development of living free-radical polymerization techniques. The technique is applied to drug delivery systems, where grafted polymers provide controlled release profiles and targeted delivery, improving therapeutic efficacy and patient compliance. In biomedical applications, grafted polymers are utilized to create biocompatible surfaces for medical implants, ensuring reduced risk of infection and improved integration with biological tissues. Radiationgrafted wound dressings are developed for their enhanced antimicrobial activity and accelerated healing properties. The chapter delves into the scientific principles underlying RIGG, detailing the mechanisms by which radiation induces grafting and the factors influencing the process. The chapter then delves into the specific applications of radiation-induced green grafting in the pharmaceutical and healthcare industries.
