“…When the energetic ions are incident on the polymer surface, several processes, such as bond breaking, chain scissoring, cross linking, formation of free radicals, formation of defects and new bonds occur in the polymer simultaneously, as discussed earlier in Raman and FT-IR studies. As a result of these processes, the absorption edge of the ion implanted samples shifts towards longer wavelengths [1,32,34]. It is clear from Fig.…”

“…The value of intensity ratio I D /I G for the ion fluence of 5 × 10 14 ions/cm 2 was found to be 0.52. This indicates that the carbonaceous structure with small amount of sp 2 C-C bonding is formed in ion implanted CR-39 [1].…”

“…These two bands are named as the well-known graphite-like G and disorder D bands of hydrogenated amorphous carbon structure. The G band is correlated to the bond stretching of all pairs of sp 2 -atoms in both rings and chains, whereas the D band refers to the breathing mode of sp 2 -atoms in rings only [1]. The value of intensity ratio I D /I G for the ion fluence of 5 × 10 14 ions/cm 2 was found to be 0.52.…”

“…which make them versatile in everyday life. In spite of these characteristics, their utilization in opto-electronics and electrical devices is still limited due to their high electrical resistivity [1]. There is a growing need to tailor the surface properties of polymers keeping the bulk properties unchanged [2].…”

Ion implantation has a potential to modify the surface properties and to produce thin conductive layers in insulating polymers. For this purpose, poly-allyl-diglycol-carbonate (CR-39) was implanted by 400 keV Au + ions with ion fluences ranging from 5 × 10 13 ions/cm 2 to 5 × 10 15 ions/cm 2 . The chemical, morphological and optical properties of implanted CR-39 were analyzed using Raman, Fourier transform infrared (FT-IR) spectroscopy, atomic force microscopy (AFM) and UV-Vis spectroscopy. The electrical conductivity of implanted samples was determined through four-point probe technique. Raman spectroscopy revealed the formation of carbonaceous structures in the implanted layer of CR-39. From FT-IR spectroscopy analysis, changes in functional groups of CR-39 after ion implantation were observed. AFM studies revealed that morphology and surface roughness of implanted samples depend on the fluence of Au ions. The optical band gap of implanted samples decreased from 3.15 eV (for pristine) to 1.05 eV (for sample implanted at 5 × 10 15 ions/cm 2 ). The electrical conductivity was observed to increase with the ion fluence. It is suggested that due to an increase in ion fluence, the carbonaceous structures formed in the implanted region are responsible for the increase in electrical conductivity.

“…Another possible effect of ion bombardment, depending on the process parameters, may be the change of polymer optical or electrical properties, e.g. decrease of optical band gap energy and significant (about ten orders of magnitude) diminution of electrical resistance (Goyal et al, 2012;Resta et al, 2014). It may be expected that ion bombardment may also find the application in modification of polymer membranes to change their hydrophilicity and thus improve their anti-fouling properties.…”

The influence of ion implantation on the structure and properties of polymers is a very complex issue. Many physical and chemical processes taking place during ion bombardment must be taken into consideration. The complexity of the process may exert both positive and negative influence on the structure of the material. The goal of this paper is to investigate the influence of H + , He + and Ar + ion implantation on the properties of polypropylene membranes used in filtration processes and in consequence on fouling phenomena. It has appeared that the ion bombardment caused the chemical modification of membranes which has led to decrease of hydrophobicity. The increase of protein adsorption on membrane surface has also been observed.
