Research

-Micro- and nano-encapsulation

We study the preparation of micro- and nano-capsule containing various materials such as heat storage materials, fragrances, fertilizer, magnetic particles and nutrition, using many techniques for example pickering emulsion, conventional suspension polymerization, and modified suspension polymerization using Phase Inversion Emulsification (PIE) to produce monomer droplet. Moreover, a simple technique as a solvent evaporation is used as well with PIE. In addition, controlled/living radical polymerization (CLRP) as iodine transfer polymerization (ITP) and reversible chain transfer catalyst polymerization (RTCP) are also implemented to prepare such capsules.

-Controlled/living radical polymerization in aqueous dispersed systems

CLRPs aqueous dispersed systems for example RTCP, ITP and so on have been utilized to produce a various kinds of polymer particles including micro- and nano-capsules, molecularly imprinted polymer particles and functional polymer particles.

PC54

-Molecularly imprinted polymer (MIP) particles

Dispersion and precipitation polymerizations are utilized to produce MIP particles for use as the stationary phase in the separation techniques. MIP represent specific cavities which in size, shape and functional groups, fit to the target molecule. To improve the binding efficiency and selectivity, CLRPs are implemented in which the homogeneous distribution of the target molecule (template) inside the MIP particle is expected to be obtained.

-Biopolymer composites

The composited films between silver nanoparticle and biopolymer such as PLLA and cellulose are prepared to use as the antimicrobial packaging. Moreover, the improvement of natural rubber properties with polymer nanoparticles was also prepared by the heterocoagulation technique.
