Self-assembled thin polymer film used for sensing application
Polymer thin films have played an important role in our everyday lives ranging from industrial to biomedical applications. In this thesis, two major topics based on polymer thin films including photopolymerized self-assembled monolayer and nanoporous thin films derived from diblock copolymer are …

Polarization-independent Liquid Crystal Devices
… modulators. For amplitude modulations, a new polymer-dispersed liquid crystal (PDLC) and two new dye-doped LC gels are polarizer-free by combining light scattering with dye-absorption effects. In phase modulation, we explore five device concepts: PDLC and Polymer-Stabilized Cholesteric Texture …

Melting point depression in biodegradable polyesters
… with time during isothermal crystallisation of a thin polymer film (<15μm) was measured. The results were normalised in order to calculate crystallisation half-life (t0.5). From half-life calculations, the optimal crystallisation temperature was found to be 118°C. By replacing the light dependant …

Field induced orientation of semicrystalline and non-crystallne block copolymer microdomain patterns
Various block copolymer microdomain structures are controlled in bulk as well as in thin film by employing flow fields, directional solidification, and substrates. In bulk systems, flow fields generated by the 'roll casting' process orient amorphous cylindrical microdomains along the flow direction …

Design and fabrication of nanostructures for thermal conductivity measurements and picosecond acoustics
… First, fabrication of sub-10nm fluorocarbon films is presented for thin film thermal conductivity measurement. Thermal conductivity of this ultra-thin polymer film is especially interested in phonon study due to its atomic confinement in one dimension. Using plasma polymerization technique, …

Interfacial cationic polymerization and its application in microencapsulation
Direct polymerization on the solid surfaces of three crystalline biologically active drugs has been carried out in this study to provide a thin polymer film (capsule wall) around the crystals. This polymer film would act as a release controlling layer of the encapsulated crystals into a surrounding …
