Polymers in Nanoscience and Nanotechnology
With the recent advances in controlled polymerization and molecular modification techniques, polymer science and engineering continue to play a key role in nanoscience and nanotechnology. The on-going research work includes molecular processing of ultra-low-k materials for nano-level electronics, polymer-inorganics nano hybrids, molecular architecture and assembly via living radical polymerization and copolymerization, molecular processing by RF magnetron sputtering and PE-CVD, and controlled plasma polymerization and deposition of nanospheres and nanostructures.
Surface modification of polymers

Molecular and Polymer Electronics
Research work in this area involves: (1)monochromatic light emitting conjugated polymers for single-layer PLEDs (2)non-volatile molecular and polymer memory for flash memory in silicon IC applications (3)wiring of functional and electroactive polymers/molecules to single crystal Si and GaAs surfaces for molecular electronics, (4) electroless metallization, (5) nano wafer level packaging.

Polymers in Biomolecular Engineering
With our established capability in surface functionalization and molecular design, work is being done to modify and re-design polymer and single crystal semiconductor surfaces and interfaces to enhance the physiological functions of the cultured cells and immobilized biological species. Well-defined functional polymer-Si hybrids, from surface-initiated graft copolymerization via ATRP and RAFT processes, are being developed for applications in BioMEMS and tissue engineering. Nanoporous and microporous “smart” membranes, which respond to environmental stimuli, as well as membranes with active or 'living' surfaces, have been successfully prepared via living radical copolymerization for biomedical and pharmaceutical applications. |
