Prof. Amanuel, Anna Gaudette ‘09 Publish Paper

Prof. Samuel Amanuel and Anna Gaudette ’09 co-authored a paper with Prof. Sandy Sternstein of RPI in the December issue of the JOURNAL OF POLYMER SCIENCE PART B-POLYMER PHYSICS. The paper, titled “Enthalpic Relaxation of Silica-Polyvinyl Acetate Nanocomposites” was based on work done by Gaudette in Prof. Amanuel’s lab at Union. They studied the effect on of adding nanoparticles on the glass transition in a rubber compound.

The paper shows that nano particles substantially reduce physical aging in polymers, which has immediate application in industry such as determining shelf life, and predicting and enhancing long-term reliability of polymer products. The paper also provides crucial evidence to understand the underlying mechanism of reinforcement in polymer composites and polymer nanocomposites.
