“…The most prominent maximum from this series was the first one, at around 29.3 • , followed by smaller ones at 35.9 • , 39.3 • , 43.1 • , and 47.3 • . These data correlated rather well with a TPU diffraction pattern reported in [29]. In contrast with TPU, significant differences were observed for the XRD pattern of TPO in the 2θ angular domain between 40 • and 65 • .…”

In this work, new films containing composite materials based on blends of thermoplastic polymers of the polyurethane (TPU) and polyolefin (TPO) type, in the absence and presence of BaTiO3 nanoparticles (NPs) with the size smaller 100 nm, were prepared. The vibrational properties of the free films depending on the weight ratio of the two thermoplastic polymers were studied. Our results demonstrate that these films are optically active, with strong, broad, and adjustable photoluminescence by varying the amount of TPU. The crystalline structure of BaTiO3 and the influence of thermoplastic polymers on the crystallization process of these inorganic NPs were determined by x-ray diffraction (XRD) studies. The vibrational changes induced in the thermoplastic polymer’s matrix of the BaTiO3 NPs were showcased by Raman scattering and FTIR spectroscopy. The incorporation of BaTiO3 NPs in the matrix of thermoplastic elastomers revealed the shift dependence of the photoluminescence (PL) band depending on the BaTiO3 NP concentration, which was capable of covering a wide visible spectral range. The dependencies of the dielectric relaxation phenomena with the weight of BaTiO3 NPs in thermoplastic polymers blends were also demonstrated.

“…It clearly shows that the prepared nanocomposites have improved thermal stability on incorporation of GHT into the pure polymer matrix. Emre et al studied the thermal stability of the polyurethane/barium metaborate composites and it was observed that the blending of barium metaborate into polymer matrix has improved the thermal behavior of polyurethane which was similar to our findings .…”

Morphological, thermal, and blood‐compatible properties of electrospun nanocomposites for tissue engineering application

In this work, the morphological, thermal, and blood compatibility properties of prepared polyurethane (PU) and gandharvahasthadi eranda thailam (GHT) nanocomposites were investigated. Morphological and thermal characterization revealed reduced diameter, improved surface roughness, and higher thermal degradation compared to control. The activated partial thromboplastin time (APTT) and prothrombin time (PT) assay revealed that the fabricated nanocomposites displayed delayed blood clotting time owing to improved surface morphology. The hemolytic assay suggested that nanocomposites would be nonhemolytic material due to low hemolytic index of about 1.15% compared to pure PU (2.733%) portraying its safety with the red blood cells. Thus, the newly developed PU/GHT composite scaffold possessing better physicochemical and blood compatibility may be considered as a potential substitute scaffold for replacing damaged tissue. POLYM.

“…Two sharp peaks at 1726 and 1702 cm −1 are correlated to the ester carbonyl group and the carbonyl stretching of the urethane groups. In addition, peaks at 1530 cm −1 and 1230 cm −1 correspond to urethane C-N stretching and N-H bending absorption, respectively [ 49 ]. The characteristic peaks of h -BN can be found in both the h -BN/TPU and ABN/TPU spectra, however, the intensity gets weaker due to the overlapping of the TPU and high-intensity additives peaks [ 27 ].…”

Thermal management has become one of the crucial factors in designing electronic equipment and therefore creating composites with high thermal conductivity is necessary. In this work, a new insight on hybrid filler strategy is proposed to enhance the thermal conductivity in Thermoplastic polyurethanes (TPU). Firstly, spherical aluminium oxide/hexagonal boron nitride (ABN) functional hybrid fillers are synthesized by the spray drying process. Then, ABN/TPU thermally conductive composite material is produced by melt mixing and hot pressing. Then, ABN/TPU thermally conductive composite material is produced by melt mixing and hot pressing. Our results demonstrate that the incorporation of spherical hybrid ABN filler assists in the formation of a three-dimensional continuous heat conduction structure that enhances the thermal conductivity of the neat thermoplastic TPU matrix. Hence, we present a valuable method for preparing the thermal interface materials (TIMs) with high thermal conductivity, and this method can also be applied to large-scale manufacturing.
