“…The low frequency region of rheological graph illustrates the nano-scale gallery influence in addition of the dispersion feature of OMMT on the viscoelastic properties of the PUC/ OMMT nanocomposites. 46 Moreover, to detect the influence of nanoclay on the rheological behaviour of the nanocomposites, the variation of modulus and h* with the frequency (!) were studied at low frequencies.…”

The remarkable structural features of organic modified montmorillonite particles (OMMT) enable them to complete their important role in enhancing different properties of polyurethane copolymer with 75 wt.% hard segments (PUC/75). Based on the melt intercalation approach, various amounts of OMMT were incorporated into PUC/75 solution followed by the injection moulding process. It is essential to mention that the synthesized PUC/75 in this work relied on using 1,5-Pentanediol as a chain extender in order to produce a long-term and thermal-stable PUC successfully. The effect of incorporating various loading of OMMT on rheological properties of neat PUC/75 and its nanocomposites was investigated. The structure of PUC/OMMT was studied using X-ray diffraction (XRD) and scanning electron microscopy. Additionally, differential scanning calorimetry (DSC) thermograms were utilized to investigate OMMT effect on the thermal transitions and crystallinity of resultant PUC nanocomposites. Interestingly, the dynamic rheological analysis exhibited a remarkable increase in melt rheology behaviour with increasing OMMT loading compared to neat PUC/75. This could imply a good interaction between the functional group on the surface of OMMT and PUC/75 domains; particularly hard domains, herein the DSC results showed moderate improvement in melt temperature (Tm) of PUC/OMMT nanocomposite. However, a decline in crystalline temperature (Tc) was also seen due to aggregation of OMMT, especially at higher OMMT loading. While XRD results exhibited a slight shifting in crystalline peaks of PUC nanocomposites relative to neat PUC/75.

“…In the current study, TPEs based on styrene‐ethylene‐butylene‐styrene (SEBS)/thermoplastic polyurethane (TPU) and maleated styrene‐ethylene‐butylene‐styrene (SEBS‐g‐MA)/TPU are subjected to EB radiation, and the effects are investigated in detail. Although there are a few studies that explore these blend systems, 14,15 no study has been reported discussing the effect of EB exposure on them. Styrenic block copolymers and TPUs are the highly consumed polymers in the global TPE market.…”

The effects of electron beam (EB) radiation in thermoplastic elastomers based on SEBS/TPU and SEBS‐g‐MA/TPU are evaluated. 60/40 blend of both the systems were subjected to EB using an ILU type industrial accelerator. Radiation dose was varied from 0 to 100 kGy, and the sol–gel content evaluation along with detailed analysis of mechanical, thermal, rheological, and morphological implications was conducted. The interplay between crosslinking and chain scission was quantified using the Charlesby‐Pinner equation. Both the blends showed the presence of a three‐dimensional cross‐linked network in them after the irradiation. The tensile strength of SEBS/TPU was found to deteriorate with an increase in radiation dose, but an opposite trend was observed in SEBS‐g‐MA/TPU. Improvement in interfacial adhesion between SEBS‐g‐MA and TPU was confirmed. The morphological analysis through atomic force microscopy and scanning electron microscopy clearly showed the appearance of rough ridges and pits due to irradiation along with the cross‐linked networks. From differential scanning calorimetry analysis, the changes in glass transitions and melting endotherm were assessed. Thermogravimetric analysis results indicated an improvement in the thermal stability of the blends. The storage modulus and complex viscosity of the samples enhanced as perceived from the rheological measurements. X‐ray diffraction patterns of the blends also showed considerable variation after irradiation.
