“…The XRD pattern show notable high intensity Bragg diffraction peaks at 2θ = 9.16° and 19.12°. These peaks are characteristic XRD peaks of poly(methyl methacrylate) [16]. The intense peak at 2θ = 19.12° indicates the crystallinity of the poly(methylmethacrylate) polymer sample while the peak at 2θ = 9.16° indicates that the polymer is amorphous in nature.…”

“…Characterization studies: Fourier transform infrared (FTIR) spectroscopy was extensively used to study the environment of chemical bonds of polymers and the supramolecular interactions between molecules through the characterization of their vibrational types [14][15][16][17][18][19][20]. FTIR spectroscopic study of the polymer was conducted to ascertain the active functional groups on the polymer accountable for attaching of Pb 2+ from solution.…”

The sorption of Pb 2+ from solution by poly(methyl methacrylate) (PMMA) waste has been investigated. The morphological characterization of the collected PMMA polymer were studied by scanning electron microscopy. Equilibrium, kinetics and thermodynamic batch adsorption experiments of Pb 2+ on the PMMA waste samples were carried out. This study enabled the determination of the concentration, time and temperature effects, respectively on the adsorption properties of the PMMA polymer. The morphological image of the PMMA polymer showed the presence of irregular small size particles that indicated a high surface which is therefore possible to facilitate sorption. The reaction kinetics of the adsorption studies of Pb 2+ by the polymer followed a second-order rate process. The results indicated that the adsorbent, PMMA, proved to be an effective material for the treatment of lead contaminated water solution. The thermodynamic studies suggested a reaction that favoured a relatively low temperature (low energy) sorption that is exothermically controlled with a physisorption mechanism.

“…The interaction of ions with polymers resulted in the formation of free radicals which may further induce chain scissoring, unsaturated bond formation and conjugated bond formation . All these processes increased with the increase of ion fluence; hence a decrease in the band gap energy took place . Another effect of shift of absorption edge towards longer wavelength is the increase in number of carbon atoms per conjugation length (N) which increased from 61 to 100 for MF‐KG polymer (Table ) and from 62 to 114 for MF‐N polymer (Table ) with the increase of ion fluence.…”

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.

“…At very high ion fluences, carbon clusters are created [5]. Earlier reports, on irradiation of PMMA included studies of the physical and chemical changes induced by 70 MeV carbon ions [6] and the effect of 145 MeV Ne 6+ ions on physico-chemical and structural properties of PMMA was also presented [7]. The effect of temperature on the mechanism of radiation stimulated degradation of PMMA was reported [8].…”
