Dr. Zhang Juanjuan is an interdisciplinary researcher whose work spans advanced functional materials, nanocomposites, and environmental geoscience, with a growing record of contributions across high-impact journals. Her research in materials science centers on understanding and engineering the mechanical, electrical, thermal, and multiferroic behaviors of polymer- and carbon-based composite systems. She has investigated the nonlinear mechanical responses and multi-field coupling characteristics of polymer-based multiferroic composites under combined tension and bending, offering critical insights for designing next-generation flexible and responsive materials. Her theoretical contributions include unified micromechanics-based models that reveal the effective electrical and thermal conductivities of MXene/polymer nanocomposites, advancing predictive capability for emerging MXene-enhanced functional materials. Zhang’s work on CNT-based nanocomposites extends to thermoelectric coupling around the glass-transition region, where she examines sensing performance and temperature-responsive characteristics essential for high-precision thermal sensors. She has also employed Monte Carlo methods to analyze electromagnetic shielding properties of CNT nanocomposite foams in the X-band frequency range, addressing challenges in lightweight, broadband shielding technologies. Beyond materials science, Zhang is a contributor to climate-focused environmental studies, including investigations into divergent phenological responses of soil microorganisms and plants to climate warming, and analyses of freeze–thaw cycle shifts along alpine wetland–grassland gradients, highlighting ecosystem vulnerabilities in a warming climate. Additionally, her work on CoFe₂O₄/P(VDF-TrFE) nanocomposites explores crystal phase transitions, multiferroic functionality, and associated biotoxicity considerations, integrating material performance with environmental and biological safety. Collectively, her research portfolio reflects a strong ability to bridge theoretical modeling, materials characterization, and environmental science, positioning her as a versatile scholar contributing to both advanced composite technologies and climate-related ecological understanding.
