Development of Nano-Particles Within Polymeric Materials Prepared by Gamma Radiation and their Possible Practical Applications

Abstract

Nanoparticles can be used in biomedical applications, where they facilitate laboratory diagnostics, or in medical drug targeting nanoparticles based on a core consisting of iron oxides that can be targeted through external magnets. Polyvinyl alcohol/Polyacrylic acid nanoparticles were prepared using gamma rays. The prepared PVA/AAc nano copolymers were treated with Fe{sup 2+}/ Fe{sup 3+} solution followed by ammonia solution to obtain PVA/AAc-Fe{sub 3}O{sub 4} nanoparticle ferrogel. Characterization of the PVA/AAc-Fe{sub 3}O{sub 4} nanoparticle ferrogel was carried out using XRD, TGA, DSc , TEM and AFM. The use of magnetic field sensitive nano-ferrogels as a drug carrier was investigated. It was found that the release of drug in absence of the effect of magnetic field is mostly slow than that under the influence of magnetic field. On the other hand, development of nanoparticles within radiation grafted polymeric surfaces using electroless plating technique was investigated. Surface modification of polypropylene films (PP) was carried out via radiation induced graft copolymerization of 4-vinyl pyridine (4VP) and acrylamide (AAm) to enhance the adhesion ability of the PP surface for electroless deposition of copper. The produced grafted films were characterized by studying their FTIR and thermal stability. The prepared grafted films were copper-plated by electroless deposition  More>>

The prepared grafted films were copper-plated by electroless deposition using the Pd as a catalyst to initiate the redox reaction. The influences of catalytic activation method parameters on the plating rate have been studied. The electrical characteristics of the copper plated films in comparison with grafted films were studied. The results showed the high adhesion of the deposited copper film to the grafted PP film as well as high electrical conductivity. (author)}
