Overview​

• In this page, I highlight my research on the mechanics and physics of polymers.

Multiscale Modelling of Elastomeric Failure​

Elastomers are rubbery networks composed of polymer chains, widely used in soft electronics and biomedical engineering. However, their long-term durability is limited by microscopic chain scission over time. I am developing a multiscale framework to better understand these failure mechanisms and guide the design of more reliable materials.

• Single-Chain Stretching: Developed statistical-mechanics models and semi-analytical dFRC model that incorporates both bond stretching and bond angle opening to accurately capture chain force-extension behaviour up to large forces.

Osmocapillary Phase Separation on Gel Surface​

Gel is a polymer network infiltrated with a solvent, widely used in flexible sensors. However, surface tension can pull the solvent out from the polymer network, a phenomenon known as osmocapillary phase separation, which alters surface roughness and affects sensor performance. To understand and control this process, I developed a theoretical model and conducted an experimental study on ionogels.

• Theoretical Modelling: Developed a linear-elasticity-based model to predict how osmocapillary phase separation affects the surface roughness and surface energy of the gel.

• Experimental Validation: Fabricated ionogels with controlled mechanical properties and validated theoretical predictions using white light interferometry to characterize surface roughness.
