Research InterestsOur interests mainly focus on “electrochemical engineering” in which its applications include electrochemical metallization processes , electropolymerization, energy sources such as batteries and fuel cells , corrosion , sensors and waste-treatment processes. We integrate the knowledge of chemistry , chemical engineering as well as electrochemistry when looking at problems in those areas. Various electrochemistry techniques and surface analysis , along with simulation studies , are used to get better understandings and insight information of the systems studied. Following are some of the specific areas that we are interested:
Metal electrodeposition
We have investigated the uses of the pulse plating and additives for electrodeposition of copper and some other metals. We characterize the deposits using scanning electron microscope and other surface analysis methods to investigate the effects of the plating mode and additives and their interaction. For copper electrodeposition, we apply the on-chip to interconnect the computer and electronic industries.
Electropolymerization
Besides the electrodeposition of metals , we will also be looking at the formation of organic and polymer coatings on metal surfaces. It can be applied for purposes of surface decoration , heat and frictional resistance enhancement , corrosion protection , modified electrodes and microelectronics. Electropolymerization is the electrolysis process used to initiate polymerization where monomer is polymerized in situ on a conducting surface. It uses low molecular weight monomers that have higher solubility in the media and more favorable viscosity and mobility compared to polymers. Unlike electrophoretic which polymer is used in the process , it does not need high potentials or chemical additives for electropolymerization.
Fuel cells
Fuel cells are electrochemical devices that generate the electric power via electrochemical reactions. They have advantages over other energy consuming devices; for example , higher efficiency and more environmentally friendly. Although there are several types of fuel cells , we are particularly interested in the proton exchange membrane fuel cell (PEMFC) since it has more potential to apply for automobiles and small power stations compared to others. The major obstacle of PEMFC is that its cost is still too high for commercial at this stage. The main goal of this research is to reduce the cost of PEMFC components such as bipolar plates , membrane , membrane electrode assembly (MEA) and fuel cell stack , but still retain or even improve its performance at the same time.
