Abstract: This research proposal addresses the critical transition from rigid electronics to flexible, multifunctional smart textiles by systematically developing graphene-based conductive textiles with tailored electrical and mechanical properties. While traditional metals offer high conductivity, their stiffness and susceptibility to corrosion limit their practical use in wearable technology. Consequently, this study explores graphene and its derivatives, like graphene oxide (GO) and reduced graphene oxide (rGO), as superior alternatives due to their mechanical strength and dispersibility. The project aims to bridge a significant research gap by investigating the molecular-level chemistry of hybrid systems where graphene acts as the primary matrix rather than just a filler. This research intends to develop available and affordable conductive fabrics through the systematic optimization of matrix-filler proportions and the synthesis of graphene-based composites. By utilizing advanced characterization techniques, the study will elucidate the structure-property relationships necessary to fine-tune electrical performance. Ultimately, this work seeks to provide detailed insights into interfacial chemistry, enabling the creation of smart textile prototypes that offer robust stability and flexibility for next-generation applications contributing significantly to the global demand for sustainable, green technology solutions.
Abstract: Achieving control over size and molecular weight of polyaniline (PAni) plays a crucial role in conductivity for its use as a shielding material in smart textiles, and this remains a challenging task. In the proposed work, an attempt will be made to regulate not only the size but also the molecular weight of PAni synthesized from aniline using a Triton X-100-based w/o microemulsion as a nanoreactor. The analysis will focus on the effect of changing two synthesis parameters—the water-to-surfactant molar ratio of the microemulsion and temperature—on the size and molecular weight of PAni, which is ultimately expected to affect conductivity. The prepared material will be characterized to explore its potential in electromagnetic interference (EMI) shielding for smart textile applications. Consequently, the proposed work would open routes to tune the conductive property of synthesized PAni for efficient EMI shielding.
