“…Actually, the decrease of Eb values with gamma radiation treatments may be clarified as: at a higher irradiation dose, there is an extra bonding formed in Composites B and C because of the large number of free radicals formed under irradiation on the ingredient. Therefore, an increased radical recombination is likely to generate strong chemical linkage with gamma radiation treatments .…”

The effect of using gamma radiation on the prepared activated carbon (AC) from carbon black using dose 500 kGy was studied. Moreover, AC powder were blended in internal mixer to prepare thermoplastic elastomer with percentage (75/25/10) wt% based on waste polyethylene and waste rubber which irradiated before mixing at dose100 kGy separately and AC. Chemical activity of composites was improved as a result of using gamma radiation which was examined by electron spin resonance estimations. Composites were studied by different techniques, such as FTIR, mechanical, thermal, morphology, and X-ray diffraction. The results indicated that optimistic effect of using gamma rays with improving the properties of the composites. J. VINYL ADDIT.

In this study, thermoplastic elastomer nanocomposites based on linear low density polyethylene (LLDPE)/silicone rubber (SR; 90:10) filled with a 2 vol% boron nitride (BN) nanofiller were exposed to electron beam (EB) irradiation at low irradiation doses (20, 40, 50, and 100 kGy). The response of the LLDPE/SR/BN nanocomposites to the EB irradiation crosslinking was examined and compared with the non‐irradiated samples in terms of dielectric properties (permittivity and loss tangent), dielectric breakdown strength, morphology, and rheological properties. A swelling study was performed to quantify the degree of crosslinking and it was found that the crosslink density increased slightly upon EB irradiation. Scanning electron microscopy results provided evidence that the SR phase was selectively crosslinked and interfacial adhesion was improved in irradiated samples. A good correlation was observed between the morphology and the dynamic storage modulus obtained from the melt rheological experiments. The optimum irradiation dose was found to be 20 kGy, which was marked by an improved dielectric breakdown strength, a permittivity‐frequency curve plateau and a reduced loss tangent value. POLYM.

The objective of this work is to analyze the possibility of thermomechanical recycling of polyamide 6 (PA6) from fishing nets waste. The effect of thermomechanical processing on PA yarns obtained from fishing nets waste was investigated by means of physicochemical, rheological, and thermal characterization. Infrared analysis indicated that the chemical composition of samples before and after thermomechanical recycling process was maintained, also confirmed by the thermal transitions detected by calorimetry and the presence of main peaks related to γ and α crystal phases of polyamides at X-ray diffraction spectra. As rheological and mechanical behavior showed by all recycled samples after processing is similar to those for virgin one, PA obtained from fishing nets waste seems to be valid for recycling, as they can be processed for different potential industrial applications without any remarkable loss of main properties.
