“…a. These explanations are in accordance with the reported investigations during the study of transparent polyacrylamide nanocomposite hydrogels with incorporation of h‐BN, which have similar trend of enhancement of tensile strength . The mechanical strength of PEHA/PVA‐s thin films is 8 MPa, when h‐BN is dispersed in to PEHA/PVA‐s solution, and which enhances with an increase in h‐BN concentration.…”

Herein, starch hybrid polyethylhexylacrylate\polyvinyl alcohol (PEHA/PVA‐s) thin films are synthesized by in situ polymerization of ethylhexylacrylate (EHA) with incorporation of hexagonal boron nitride (h‐BN). The occurrence of h‐BN nanoparticles in PEHA/PVA‐s thin films is characterized by Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD), and energy dispersive X‐ray (EDX) analysis. The field emission scanning electron microscopy (FESEM) images illustrates the embedment of h‐BN nanoparticles in the PEHA/PVA‐s films. It is found that, h‐BN nanoparticles have an average particle size of 100 nm observed with a lattice fringe of 0.35 nm are known from high resolution transmission electron microscopy (HRTEM) images. The surface and nano‐tribological features of thin films are studied by atomic force microscope (AFM). The thermal conductivity of films is enhanced with increase in h‐BN concentrations. From rheological study, it is observed that, the tan δ value varies from 0.3 to 0.5. The biodegradation, refractive index, and chemical resistance properties of the thin films are studied. The oxygen barrier properties of the thin films are substantially reduced by 18 folds due to incorporation of huddled h‐BN layers. The prepared PEHA/PVA‐s@h‐BN thin films with improved physicochemical behaviors and reduction in gas barrier properties can enable the material for packaging applications. POLYM.

Recently, boron nitride (BN) based materials have received significant attention in both academic and industrial sectors due to its interesting properties like large energy band gap, good resistance to oxidation, excellent thermal conductivity, thermal stability, chemical inertness, significant mechanical property and widespread applications. This review article deals with the preparation and properties of boron nitride and its nanocomposites with various polymers. Diverse polymers have been explored for the preparation of boron nitride filled polymer nanocomposites by adopting different mixing methods. Properties of the resulting polymer nanocomposites mainly depend up on filler size and dispersion, mixing conditions and type of interaction between polymer matrix and the filler. Herein, the structure, preparation and properties of various boron nitride based polymer nanocomposites are reviewed in detail along with a brief overview of different classes of BN nanomaterials.

“…For instance, research has shown that BNNTs possess a Young's modulus of up to 1.3 TPa which is approaching that of CNTs ( Y = 1.3–1.8 TPa), while their resistance to failure can possibly surpass that of CNTs, as the experimental results from seem to suggest. On the other hand, hexagonal boron nitride (h‐BN) nanosheets filled polyacrylamide (h‐BN/PAM) nanocomposite hydrogels are highly transparent, and exhibit significantly enhanced mechanical properties compared to the dark graphene oxide (GO)/PAM nanocomposite hydrogels or chemical crosslinking PAM hydrogels . Owing to this interesting performance, these materials have received increasing attention among all types of reinforcing nanofillers that are investigated for polymer nanocomposites.…”

Thermoplastic elastomer (TPE) has gained acceptance as third generation of polymeric materials for high voltage (HV) insulators. The interesting features showed by TPEs were found to fulfill some particular requirements for HV insulations, at least for the distribution class applications, especially at light contamination environments. Introduction of nanomaterials which widely reported to give significant improvements in the electrical, mechanical, thermal and other properties of polymer has attracted attention to the synergistic properties of combining the two complementary technologies of thermoplastic elastomers and nanocomposites. In this paper, research works on various types of TPEs having promising performance as HV insulators are thoroughly reviewed. The emergence of nanocomposites in the electrical insulation field and the important properties consideration for HV insulators as well as the processing techniques of TPE nanocomposites are also discussed. Finally, some of the past and recent developments of TPE nanocomposites focusing on the electrical insulation properties are highlighted in this article. POLYM. ENG.
