Work in M.Sc. on the Topic of “A Study of Volumetric Property of Spirosilicate, Aminospirosilicates and Benzoxazines Based on Synthesized Aminospirosilicate Derivatives”


Idealistic materials used in many applications should have dimensional stability. However, almost thermosets are cured with high shrinkage. The volumetric property of spirosilicate, new aminospirosilicate derivatives cured without catalyst was investigated by measuring the change of the density in the cured resins as compared to their corresponding monomers. Shrinkage property increased with increasing in the number of carbon in the diol’s structure. It was appeared that the hydrogen bonding in the system played an important role, resulting in high packing of polymer chains. Aminospirosilicates were further used as starting materials for novel benzoxazine synthesis to determine their volumetric change, as well.

Work in Ph.D on the Topic of “Polymerization of isoprene via the RAFT process and its application to the design of nanoparticles”


This work has shown, for the first time, that isoprene polymerization can be controlled by the RAFT process, to obtain living poly(isoprene) chains of controlled molecular weight and narrow polydispersity. The ‘living’ nature of the system was exploited to synthesised block copolymers of poly(acrylic acid-block-isoprene) (P(AA-b-I)), and their self assembly in aqueous media were studied. Shell cross-linking of the resulting spherical micelles, followed by core-modification via ozonolysis, generated ‘hollow’ nanoparticles. In order to gain better control over the particle size, the P(AA-b-I) block copolymers were also used to mediate, for the first time, the RAFT emulsion polymerisation of isoprene to obtain an uniform latex. The shell of the latex was ‘locked’ by cross-linking and the resulting particles were functionalised, with glucose and fluorescence moieties, via reactions on the double bond of the PI chain, to form glucose and pyrene core-functionalised nanoparticles.
