The article focuses on synthesising a new nanocomposite incorporating ZnS filler and investigating its structure, optical properties and specific electrical conductivity. In this study, expanded perlite (EP) and butadiene rubber (BR) underwent simultaneous oxidative chlorophosphorylation and subsequent hydrolysis. ZnS nanoparticles were then grown on the crosslinked/ion-exchange composite (EP-PhBR) using the Successive Ionic Layer Adsorption and Reaction (SILAR) method, resulting in the ZnS/EP-PhBR nanocomposite. The structure of the nanocomposite was characterised through UV-Vis spectroscopy and X-ray diffraction analysis. Embedding ZnS nanoparticles in EP-PhBR caused a reduction in the optical band gap from 3.18 eV to 3.045 eV, signifying increased disorder in ZnS nanoparticles due to alterations in the nanocomposite's intermolecular structure. XRD studies revealed cubic crystal-structured ZnS nanoparticles with an average size of approximately 3 nm in the ZnS/EP-PhBR nanocomposite. The specific electrical conductivity (sigma) at ambient temperature demonstrated the enhanced crystallinity of EP-PhBR, attributed to interfacial interactions with ZnS nanoparticles and the developed nanolayers. The ZnS/EP-PhBR nanocomposite exhibited favourable properties, making it a promising material for photocatalysis and solar cell applications.
