“… 1–3 The applications include shielding materials, thermal blankets, solar sails and arrays that depend on its reliable thermal stability and performance. 4–6 When exposed to damaging environments with effects of protons, electrons, solar ultraviolet radiation or thermal cycling, the microstructure and properties of polyimide will strongly be affected and tends to degrade gradually, which will lead to reducing the reliability of components in spacecraft or even mission failure. 7–13 Consequently, it is important to figure out the degradation behavior and mechanism of polyimide under these threatening environments.…”

“…Improved biocompatibility of polymer surface doped, for example, with carbon black [81] or carbon fibres [82], was studied. It has also been found that the cell adhesion and proliferation could be affected by carbonization of polymer surface layer by pyrolysis [83], ion implantation [84], UV-light irradiation [29], or exposure to plasma discharge [85]. Both, the biocompatibility of a polymer and its suitable mechanical, electrical, or other properties, are very important for the use as medical implant.…”

Polymers with their advantageous physical, chemical, mechanical, and electrical properties and easy manufacturing are widely used in biology, tissue engineering, and medicine, for example, as prosthetic materials. In some cases the polymer usage may be impeded by low biocompatibility of common synthetic polymers. The biocompatibility can be improved by modification of polymer surface, for example, by plasma discharge, irradiation with ionizing radiation, and sometime subsequent grafting with suitable organic (e.g., amino-acids) or inorganic (e.g., gold nanoparticles) agents. In this way new chemically active structures are created on the polymer surface, and in some cases new surface relief is created. Recent advances in nanotechnology and in characterization of nanostructured objects open the way to development of new polymer-based materials with better bio-properties and higher application potential in biomedicine. Some of recent results obtained in the field are summarized and discussed in this paper.

The surface morphology, chemical, optical, and structural response of 1.25 MeV gamma rays irradiation at various doses ranging from 16 to 300 kGy on Kapton polymer samples were studied by using scanning electron microscope (SEM), Fourier Transform Infrared (FTIR), ultraviolet/visible absorption (UV/VIS) and X‐ray diffraction (XRD). The morphology study shows the blisters formation on the Kapton polymer surface due to 1.25 MeV gamma rays irradiation at ambient temperature. This observation provides a basis for the quantitative evaluation of FTIR results obtained for thermally stable polymer on the chemical bond deterioration with increasing gamma irradiation. The blistering mechanism is correlated with the internal gases (CO, H2) released due to gamma radiation induced damages. The recorded UV–VIS spectrum shows a maximum absorption around the wavelength 540 nm. However, the nature of the spectra does not change due to gamma irradiation but a shift in absorption edge towards the higher wavelength side has been observed with increasing dose. The optical data shows an increase in the calculated band gap at the highest dose. The diffraction pattern of virgin sample shows that polymer is semicrystalline, but due to irradiation, a decrease in the peak intensity and FWHM and an increase in the crystallite size at the highest dose level of 300 kGy have been observed. © 2011 Wiley Periodicals, Inc.
