There have been numerous challenges in the incorporation of photochromic materials into hydrogel system due to the agglomeration of nanoparticles and non‐transparency of the hydrogel material. In this study, WO3 nanocomposites were prepared and incorporated into poly(hydroxyethyl acrylate) (pHEA) and polyacrylamide (pAAm) to fabricate poly(HEA‐AAm)/WO3 hydrogels with improved coloration efficiency and reversibility. The as‐prepared p(HEA‐AAm)/WO3 hydrogel displayed remarkable mechanical properties to sustain compressive and tensile stress up to 15.9 and 58.7 MPa with deformation ratios of 16.2 and 30.8, respectively. The hydrogels exhibited good transmittance (%T) and reflectance (%R) of ~47% and 64% at 829 and 408 nm respectively. The hydrogels also revealed visible spectroscopic absorbance at >781 nm after exposure to UV‐lamp and natural sunlight for 5 s and 0.5 h, giving rise to a blue coloration, however, the fading process of the hydrogels was achieved in 20 min and 2.0 h respectively in an open air. More so, the hydrogel solutions displayed a high antibacterial efficacy against bacteria pathogens associated with bacterial keratitis in contact lens care solutions. The observed excellent photochromic and antibacterial properties of the hydrogel show promising potentials for use in the construction of antibacterial contact lenses, optical and intelligent devices.

The silver nanoparticles (AgNPs) have been embedded within the itaconic acid (IA), polyaniline (PANi), and copper oxide (CuO) to form Ag@PANi-IA-CuO polymeric nanocomposites. In-situ polymerization of itaconic acid has been carried out in the presence of aniline monomers using anhydrous iron trichloride as an oxidising agent. The piper betel leaf extract was used to a reduction of AgNO3. The anchoring of AgNPs onto nanocomposite has been characterized using different techniques such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED) X-ray diffraction (XRD), and energy-dispersive X-ray (EDX). Biological, magnetic, and thermal properties of nanocomposites have also been studied in antimicrobial, vibrating sample magnetometer (VSM), and thermogravimetric analysis (TGA). Hence, these types of silver nanoparticles anchored polyaniline-itaconic acid-CuO nanocomposite has shown an attractive application in the field of biomedical and wastewater treatment.

“…Recent studies have produced conducting PANI composites by employing several techniques, including sol-gel method [21], chemical methods [22], electropolymerization method [23], in-situ chemical oxidation polymerization [24], insitu polymerization technique [25], solution casting [26], via a sonochemical method [27], and aqueous solutions [28]. The irradiation of polymers is achieved using either gamma-rays, electron beams, or ionizing radiation [29].…”

Conducting polymer composites such as conducting polyaniline composites have numerous attractive physical properties which could be used in several vital applications. In order to give composite materials unique physical and chemical properties that can have broad application potential in various areas, it requires appropriate adding of metal chloride through conductive polymer composites. This study employs the gamma radiation technique to produce conducting polyaniline from an aqueous solution. The solution comprises four materials, including: ANI, PVA, MgCl2 and distilled H2O, which serve as a binder or film support, precursor, Cl ions provider, and a solvent. To attain the conducting polyaniline composite, a film of ANI-PVA-MgCl2 was subjected to gamma radiation under ambient conditions. Conducting polyaniline composite has been formed once the colour began to change from white to green following the doses of radiation. The results have demonstrated that the level of gamma radiation increased to 40 KGy, thereby confirming that the electrical insulation ANI-PVA-MgCl2 film was converted into an electrically conductive polyaniline composite film. The production of conducting polyaniline composite has been observed since the colour has been changed from white to green colour alongside radiation doses.
