Current/Recent Programs

My research programs encompass the following broad areas:  1)  development of formaldehyde-free wood adhesives from renewable natural resources, 2) development and characterization of new environmentally friendly pressure sensitive adhesives from renewable natural resources, 3) development and characterization of superior natural fiber reinforced polymer composites, 4) investigation of interfacial chemistry of natural fiber-reinforced polymer composites, 5)development and characterization of new environmentally friendly foundry sand binders from renewable natural resources

Development of Formaldehyde-Free Wood Adhesives.  There are two important issues associated with the currently used wood adhesives, phenol-formaldehyde (PF) and urea-formaldehyde (UF), in the forest products industry:  1)  These synthetic adhesives are petroleum-based, whereas the resources for petroleum are naturally limited; 2)  Hazardous compounds such as formaldehyde may be emitted in the production and the use of wood composites bonded with PF and UF resins.  Our objective for this study is to develop a commercially viable formaldehyde-free wood adhesive from renewable natural resources for production of wood composites.  

Inspired by the strong and water-resistant bonding of marine organisms such as mussels to rocks and other substances, we are investigating conversion of renewable natural resources such as soy protein, carbohydrates, and lignin to strong and water-resistant wood adhesives.  At present, one of our formaldehyde-free soy-based adhesives is commercially used for production of decorative plywood.  A second generation of a formaldehyde-free wood adhesive that consists completely of natural materials, i.e., does not contain any petrochemical-based products is being evaluated at a mill scale for production of plywood panels.  

 Development and characterization of new environmentally friendly pressure sensitive adhesives from renewable natural resources.  We have recently invented three independent environmentally friendly pressure sensitive adhesive technologies from renewable materials such as vegetable oils.  One of the adhesive technologies has been licensed by a big company and commercialization of the technology is ongoing.  We are seeking for industry partners to commercialize the other two technologies.  Our pressure sensitive adhesives are either solely based on renewable materials or use a small amount of petrochemicals.  No toxic chemicals or organic solvents are used in the preparation of our adhesives.  The adhesives and the process of making the adhesives are very environmentally friendly.  The adhesives are cost-competitive to existing petrochemical-based pressure sensitive adhesives.

Development and characterization of superior natural fiber-reinforced polymer composites.  We are developing and characterizing novel natural-fiber-reinforced unsaturated polyester composites.  We focus on use of bamboo fibers as reinforcing materials.   

 Investigation of interfacial chemistry of natural fiber-reinforced unsaturated polyester composites.  Natural fiber-reinforced polymer composites such as bamboo-reinforced unsaturated polyester composites are one of the fastest growing sectors in the composites industry.  However, the interface between the natural fibers and the polyester is typically weak and fails to transfer stress between the phases.  Consequently, the full strength of the natural fibers is unavailable to reinforce the polyester.  One solution to this problem is the use of a coupling agent that bridges the interface and improves the stress transfer between the natural fibers and polyester.  We are developing a superior family of coupling agents and gaining a better understanding of interfacial chemistry of natural fiber-reinforced polymer composites.

Development and characterization of new environmentally friendly foundry sand binders from renewable natural resources.  We have recently invented novel environmentally friendly foundry sand binders from carbohydrates.  We are currently seeking industry partners to commercialize this novel technology.

Development of novel styrene-free unsaturated polyester resins.  Conventional unsaturated polyester resins all contain a high amount of carcinogenic styrene.  We are developing styrene-free environmentally friendly unsaturated polyester resins from renewable materials.
