Natural rubber latex viscosity varies with solid content, density, and surface charge interactions. Using rheometry measurements, I characterized these relationships and developed a predictive model to interpret the experimental data for formulation optimization.
Impact: Reduced formulation trial-and-error time and enabled accurate viscosity predictions for manufacturing scale-up.
Understanding the internal structure of latex particles is critical for optimizing processing. I used advanced NMR techniques (DOSY, relaxometry) to characterize diffusion and relaxation behavior of particle surfaces vs. cores.
Impact: Revealed structure-property relationships enabling better control of latex formulation and processing parameters.
Conventional 3D printing materials lack the elasticity needed for soft robotics and biomedical applications. I developed a photopolymerization-based process for printing natural rubber latex achieving 900% elongation.
Impact: Enabled additive manufacturing of ultra-high-elongation elastomers, opening new applications in soft robotics and flexible electronics.
