Md Joherul Alam is a Ph.D. researcher in Electrical and Information Engineering at Adelaide University, specialising in advanced dielectric polymer nanocomposites for electrical and energy-related applications. His research focuses on the development of multifunctional polymer nanocomposites reinforced with functionalised nanofillers, particularly BaTiO₃ and CuI nanoparticles.
His work centres on interfacial engineering and nanoparticle surface modification using dopamine (PDA), silquat-based quaternary ammonium compounds, and related functional molecules to enhance multifunctionality, filler dispersion, mechanical flexibility, and interfacial polarisation. A major objective of his research is to achieve high dielectric permittivity and improved electromechanical performance at low filler concentrations while maintaining low dielectric loss and good mechanical integrity.
Joherul’s research has strong relevance to flexible electronics, dielectric elastomer generators, soft actuators, capacitive energy storage systems, wearable electronics, and next-generation functional materials. His work also explores bio-inspired assembly methods and cellulose nanofibril-based hybrid structures for advanced multifunctional composites.
He has extensive experience in nanocomposite synthesis, nanoparticle functionalization, thin-film fabrication, and advanced materials characterization techniques including FTIR, XPS, Raman spectroscopy, XRD, TGA, SEM/TEM, dielectric spectroscopy, and mechanical testing.
Joherul completed his Bachelor’s degree in Electrical Engineering at Universiti Tenaga Nasional and later completed a Master’s degree in Electrical and Information Engineering at University of South Australia. Alongside his doctoral research, he has experience as a casual academic and research assistant, contributing to laboratory teaching, workshop instruction, and engineering education support.
His long-term research goal is to contribute to high-impact advancements in dielectric materials, multifunctional nanocomposites, and soft electronic technologies through innovative materials design and interfacial engineering strategies.
