    Herrington Professor in Advanced Materials

    Director

    New Product Development Center

    I was the Carl G. and Gladys L. Herrington Professor in Advanced Materials at the Helmerich Research Center

    Oklahoma State University

    Tulsa campus till June 2011. The Herrington Professorship focuses on research involving composite materials in OSU’s College of Engineering

    Architecture and Technology. \n\nMy role at OSU-Tulsa will be to connect the university with local industry and business partners and help Helmerich Center faculty take their research to commercialization. I will also seek out new research opportunities

    particularly those that will contribute to the growth and success of businesses in northeastern Oklahoma. The Helmerich Research Center is designed to be a driver in economic development in Oklahoma and particularly around the Tulsa area.\n\nI work with small manufacturers in the state of Oklahoma to solve their product development problems. My colleagues assist them with business planning and business communications. \n\nI also assist small manufacturers to apply for Small Business Innovation (SBIR) and Small Technology Transfer Research (STTR) grants to various government agencies. Additionally

    I also work with faculty members in engineering and agriculture to develop applications with polymer composite materials for multifunctional applications.

    Photooxidation of Epoxy-Based Nanocomposites

    Epoxy composites have been extensively used as coatings

    structural elements

    and insulators. However

    epoxy composites deteriorate under Ultraviolet (UV) exposure and in high temperature/humidity environments. The present work investigates photooxidation of epoxybased nanocomposites by optical spectroscopy as well as vibrational spectroscopy. The nanocomposite film samples were prepared by spin-coating on quartz. Under UV exposure

    the optical absorption reveals systematic rise of a broad optical absorption band peaking at 280 nm that is responsible for the formation of yellow color. Further

    this degradation is found to be enhanced by the presence of water. We attribute broadening of the optical absorption band to n to * transitions in carbonyl groups

    which form due to the replacement of ­CH2­or ­CH­ sites by C=O. Therefore

    we associate the degradation mechanism with the UV-generation of active oxygen and hydroxyl species. Fullerenes are known to produce reactive oxygen species during photoexcitation. Accordingly

    to confirm the effect of active oxygen

    we explored photooxidation for C60-blended epoxy polymer films. In the presence of C60

    the development of the 280 nm band was found to be significantly faster. The degradation rate was also found to be increased in the presence of nanoclay as the filler. The adverse effect of the nanoclay is credited to the inherent ammonium salts as well as the acidic sites that facilitate the cleavage of C­H bonds by oxygen.
