Original Article


The current investigation reveals the development of a synthesis route of NPs functionalized graphene through in-situ technique. An approachable platform for achieving dense, uniform, homogeneous coverage, smooth partial reduction with the formation of aggregate-free layers. The self-assembled NPs from the precursor solution behave as efficient solid-state exfoliants to detain re-stacking pattern of the nanosheets. Subsequently, the decorated product was chemically reduced through an ambient green reductant to provide the nanohybrid with tailored functionality and porosity characteristics. Moreover, a comparative analysis for the parent nanofillers including mSiO2 and GO has been investigated. The samples were characterized by the spectroscopic techniques to validate the influence of decoration and the extent of reduction. Furthermore, the particle size distribution analysis and zeta-potential measurements were accomplished; meanwhile, the surface chemistries were authenticated by employing electron microscopic techniques such as FESEM and TEM. All these discussed characterizations endorsed the formulation and proficiency of the nanofillers as promising building blocks to fabricate high-performance nanocomposite structures.
