“…Moreover, the passage of SHI creates latent tracks causing the zone predominantly amorphous. Therefore, the equilibrium between crosslinking and chain scission depends on the evolution of temperature during irradiation ,. High temperature may lead to the degradation product in the form of gas evolution which can be measured using residual gas analyzer or by time of flight principle.…”

In this review, we focus on the effect of high energy swift heavy ion irradiation on fluoropolymers and their nanohybrids, prepared through dispersion of few weight percentage of organically modified nanoclay in polymer matrix, for the fabrication of new generation fuel cell membrane. A variety of chemical, physical and structural changes are revealed with superior properties in nanohybrid. In addition, radiation resistant nature of the polymer has been discussed with improved properties including formation of nanopores and high proton conductivity of the functionalized nanopores having sufficient mechanical strength which are essential requirements for any fuel cell membrane. Membrane electrode assembly has been demonstrated having very good power density and the developed membrane has the potential to replace the expensive Nafion as standard membrane currently being used in fuel cell membrane. Further, nanoclay induced piezoelectricity in polymer matrix is attractive for the fabrication of a smart membrane using swift heavy ions.[a] Dr.

“…SEM image of ZnS nanoparticles synthesized by micro emulsion method. Here a is the absorption coefficient, hm is the photon energy, B is band tailing parameter and E g is the value of energy band gap for indirect transition [28]. The band gap of the nanocomposites films were calculated by the extrapolation of the plot of (ahm) 1/2 versus (hm) [29].…”

Summary: Makrofol (KG & N) polymers are the important class of polycarbonates which are used as solid state nuclear track detectors. The effect of 100 MeV oxygen ions (O 7þ ) on the free volume and physico-chemical properties of Makrofol (KG & N) polymers were studied. The pristine and irradiated samples were characterized by positron annihilation lifetime spectroscopy, X-ray diffraction, UV-visible and FTIR. A comparative study of free volume was carried out from the obtained values of the pristine and irradiated samples of both the polymers. The absorption edges of UV-visible were found to be shifted towards longer wavelength region. The intensities of the various absorption bands of the infrared spectra were found to be modified; which indicated the changes in the chemical properties of the exposed samples.
