Synthesis and characterization of smart polymers obtained by gamma-ray

Abstract:

Recently, the smart or intelligent polymers are synthesized and modified by gamma-rays;they have showngreat potential in advanced materials. In this chapter, the smart polymers were reviewed from their preparation, properties and potential applications. The combination of smart polymers and drug delivery systems provides specific characteristics for intelligent materials and might be encouraged to hold enormous chances in biotechnology applications. Graft copolymers and hydrogels were modified by gamma radiation of pH and thermo sensitive monomers. The effects of the absorbed dose, monomer concentration and reaction time were discussed in this chapter. The surface chemistry of smart materials was analyzed by FTIR-ATR spectroscopy, while their thermal properties were analyzed by TGA and DSC. The stimuli-responsive behavior was studied by swelling and contact angle in water, as well as by DSC. Sensitive films presented a critical pH and LCST. © 2013 by Nova Science Publishers, Inc.
