“…The C-H stretching and bending was ascribed to the bands at the spectral region of 2869 cm −1 and 1427 cm −1 , respectively (Figure 5b) [36]. From the hBN spectra shown in Figure 5c, the typical stretching vibration bands of B-N bond and B-N-B bending vibration were attributed around the spectral region of 1338 cm −1 and 767 cm −1 [37,38]. The IR spectrum of the various nanocomposites scaffolds are represented in Figure 5d.…”

The present research focused on the fabrication of biocompatible polyhydroxyalkanoate, chitosan, and hexagonal boron nitride incorporated (PHA/Ch-hBN) nanocomposites through a simple solvent casting technique. The fabricated nanocomposites were comprehensively characterized by Fourier transform infrared spectroscope (FT-IR), field emission scanning electroscope (FESEM), and elemental mapping and thermogravimetric analysis (TGA). The antibacterial activity of nanocomposites were investigated through time-kill method against multi drug resistant (MDR) microbes such as methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli) K1 strains. In addition, nanocomposites have examined for their host cytotoxicity abilities using a Lactate dehydrogenase (LDH) assay against spontaneously immortalized human keratinocytes (HaCaT) cell lines. The results demonstrated highly significant antibacterial activity against MDR organisms and also significant cell viability as compared to the positive control. The fabricated PHA/Ch-hBN nanocomposite demonstrated effective antimicrobial and biocompatibility properties that would feasibly suit antibacterial and biomedical applications.

“…PANI incorporation extended the absorption in the visible light region; similarly, PPy showed good catalytic activity and narrowed the bandgap of the composite [98]. PANI under light irradiation behave as an efficient electron donor and hole transporter, and, hence, used in combination with limited metal oxides [104]. In a study, boron nitride was supported with PANI and thereby applied to remove carcinogenic dyes [104].…”

The nanostructured materials offer various advantages as they provide more flexible space for ease reconstruction, as their nanosize expands the limits and results in confinement effect, enhanced mechanical stability, and large surface area, and make them suitable for photocatalytic activities. The advancement in synthesis techniques provides the freedom to alter its physical properties as per the demand. This article provides a 360° view point on the nanomaterials which are used for solar energy harnessing with respect to environmental and energy application. The discussion emphasizes on various synthesis methods of nanostructured materials, their mechanistic features, usage in demanding applications such as photosplitting of water for hydrogen production, artificial photosynthesis, and water and wastewater treatment with an endnote highlighting the future scope of nanomaterials for real-world applications.

“…Meanwhile conjugated conducting polymers (CPs) have been exploited to tune the thermo‐physical properties of the NFs 15 . In addition, the integration of CPs with two‐dimensional (2D) nanostructures has opened up new possibilities to construct multipurpose composites 16 . Apart from the use of polymer composite‐based NFs, the construction materials for the heat exchanger are also being replaced with polymer matrixes due to economic feasibilities 17,18 .…”

“…Therefore, scientific community has initiated to explore the thermal potential of hybrid‐polymer fillers for their thermal conductivity improvements 13,19 . Regarding polymer‐based NFs, among many CP nanomaterials, PANI has got much attention due to its intrinsic conducting properties, non‐toxicity, easy synthesis, cost effectiveness, environmental robustness and unique surface chemistry 16,20 . Owing to the high charge mobility (free electrons) at molecular level, PANI has shown anomalous augmentation in electrical conductivity in intrinsic as well as in nanocomposite forms 21,22 …”

Summary In this study, polyaniline (PANI) nanocomposite‐based nanofluids (NFs) in ethylene glycol were obtained with a two‐step method by varying volume concentrations from 0.005% to 0.02%. Tungsten disulphide (WS2) nanoparticles were doped in PANI having different weight percentage (1%, 2% and 5%) via oxidative in situ polymerization employing ammonium persulphate oxidant in an acidic environment. The nanocomposites were comprehensively characterised using various techniques, such as Fourier transform infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy and high‐resolution transmission electron microscopy. The formulated NFs were extensively investigated with zeta‐sizer, particle size analyzer, thermal property analyzer and rheometer in a temperature range of 25°C to 70°C. The zeta potential results (up to 54.5 mV) were evident of extraordinary stability of NFs at all targeted temperatures along with polydispersity index <30% and mean particle/agglomerate size in the range of 335.8 to 489 nm. Additionally, a remarkable thermal conductivity improvement (~20.7%) was achieved with intrinsic PANI‐based NFs at an operating temperature of 50°C. Subsequently, it varied substantially with WS2 doping within PANI matrix and reached to 117.9%. Furthermore, the rheological measurements have revealed the viscoelastic nature of NFs along with a remarkable reduction in apparent viscosity (up to 8.4%). The temperature sweep viscosity indicated the transition of relative viscosity from high to low at a critical temperature of about 55°C. The NF10 (WS2 + PANI 5, at 0.005 vol%) was found to be the best candidate with 63.8% thermal conductivity enhancement and 6.4% viscosity reduction as compared with the base fluid at an operating temperature of 50°C. Thus, WS2 doping within PANI has proved to be crucial in the proliferation of thermal conductivity and mitigation of viscosity.
