Model polyamide thin film RO membranes for structure-property study • Developed spin-assisted molecular layer-by-layer deposition process to fabricate polyamide thin films with tunable thickness, surface roughness and surface chemistry. • Demonstrated that surface chemistry can be controlled by the last reaction step (m-phenylene diamine or trimesoyl chloride): amine-rich (basic) or carboxylic acid-rich (acidic) Self-healing coating systems • Developed a new class of elastomers with widely tunable thermo-mechanical properties using binary mixtures of a polar polymer and a high-melting ionic liquid. • Demonstrated that small surface scratches can be healed by mild heating through thermal flow of the coating layer.

Locally anisotropic polymer membranes • Demonstrated that mixtures of high melting crystallizable diluents and compatible polymers can develop unique anisotropic microstructures. Constructed theoretical phase diagrams for thermodynamic interpretation of the process. Self-reinforcing polymer composites • Demonstrated simultaneous enhancement in processability and toughness of novel polymer composites using organic molecular crystals as dual functionality additives.
