“…The heat capacity change (DC p ) is proportional to the quantity of amorphous regions in the specimen. 30 With the addition of rPET, the DC p of rPET/TPU composites showed an increasing trend when compared to pure TPU. However, there was no striking change in the CNTs/rPET/TPU composites, which suggested that the introduction of rPET increased the amorphous region of the TPU matrix and the CNTs could not change the amorphous region of the rPET/TPU composites apparently.…”

“…Other peaks indicated the existence of carbon bonds in the N−H region of the urethane chain in the PC composite. The stretching frequency of the OH functional group was observed at 3349 cm −1 [19]. The peaks at 1596 cm −1 and 1460 cm −1 were due to the stretching frequency of C=C in the aliphatic chain and the aromatic ring, respectively.…”

Electrical transmission overhead lines use an aluminum conductor in services. However, protection of the aluminum conductor from corrosion has to be considered. Hence, an extensive experimental work was done to prepare the composite coating of the aluminum conductor. Three types of polyurethane composites were fabricated with different fillers (5 wt% carbon and 5 wt% organoclay) and were characterized. The composites were polyurethane/carbon (PC), polyurethane/organoclay (PClay), and polyurethane/carbon/organoclay (PCClay). Thermogravimetry analysis and Fourier transform infrared spectroscopy were conducted to obtain thermal properties and chemical bonding of the composites. To obtain the corrosion resistance, salt spray tests were applied. To obtain hydrophobicity properties, the contact angle between water and the composites was measured. Measurements of composites relative permittivity was conducted to obtain dielectric properties. A water vapor permeability test was conducted to obtain the rate of water/gas vapor discharge. Finally, an adhesion test was conducted to obtain adhesion performance according to the ASTM D3359 standard. Based on characterization, PCClay had better characters to be used as an overhead aluminum coating material followed by PC and PClay.

“…Polyurethanes (PUs) are one of the most important classes of materials in polymeric era with incredible various properties such as eco‐friendly, hydrophobic or hydrophilic nature, excellent elasticity, toughness, chemical resistance, etc . Wide spectrum of the PU's properties derived from the nature of their ingredient like polyol, isocyanate, chain extender, and crosslinker which are variable and could be changed in regarding to the product application .…”

4-Aminophenyl disulfide and bis(4-aminophenyl)methane chain extenders containing hydroxyl-terminated polybutadienebased polyurethane-ureas are prepared one-shot to explore the effect of the chain extender structure on the elastomers mechanical properties. However, the results revealed that the participation of the disulfide chain extender in side reactions like thiol-ene and proton abstraction prevented disulfide metathesis reaction due to decomposing chain extender in the polyurethane-urea matrix. Also, these side reactions improved the phase mixing via chemical crosslinking between polyurethane-ureas soft and hard segments, too. Tensile test results showed higher stress strength of the elastomers in the presence of the disulfide chain extender in comparison with the nondisulfide bond containing elastomers. This result was in agreement with the observed result in dynamical mechanical analysis. Dynamic mechanical analysis results established that the absence of the disulfide bond in the polyurethane-urea matrix led to the higher viscous modulus. The swelling test revealed chemical crosslinking increased in the presence of the disulfide bond. V C 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46309.
