The different types of nanomaterials including solid, hollow, one-dimensional-(1D), two-dimensional-(2D) and three-dimensional-(3D) nanomaterials including clay-based composite membranes are discussed. Along with different types of nanoparticle composite membranes, different methods of making membranes such as dip coating, composite membranes and non-woven mats are also included in the article. The research shows that direct inclusion of the nanoparticles in the polymer as well as solution gel techniques require a precise ratio of the polymer and particles, blending time and a controlled drying temperature. The strong interactions of inorganic nanoparticles with polymers not only tune the pore structure of the proton exchange membrane for promoting Grotthuss and vehicular mechanisms but also create a link to hydrophilic functional groups that promote the further refining of these nanoparticles.

Currently, halide perovskites are successfully employed not only in photovoltaics but also in many other related potential optoelectronic applications. Therefore, the origin of their multifunctional properties, remarkable energy harvesting and emitting efficiency and the corresponding potential applications in various optoelectronic devices have become controversial issues and hot topics of academic research. In this review, the nano-engineering strategies, microscopic origins and mechanisms of halide perovskites are reviewed in detail to clarify the origin of their multifunctional properties, such as tunability, ferroelasticity, piezoelectricity, pyroelectricity and thermoelectric properties. Moreover, the coexistence of multiple properties in halide perovskites enables synergistic applications and multifunctional perspectives, such as emerging energy harvesting, conversion technologies, nano-plasmonic sensing and electromechanical applications, which are now open for the scientific community for further detailed investigations. To successfully explore this field, advanced nanometer-scale domain characterization tools are highly relevant to understand the microscopic origin of these electrical properties, which will benefit commercial enterprises and research institutions. The primary aim of this review is not only to highlight the microscopic origin but also identify the factors and issues affecting the successful understanding and presence or absence of these electrical parameters.
