  1. Polymer-Based Nanocomposites: An Educational Opportunity for Deaf and Hard of Hearing StudentsPeggy Cebe, Tufts University, DMR 0704056 Background– Nanocomposites are mixtures of two or more components, in which at least one of them has dimensions on the nanometer length scale. Here, polymer nanocomposites are made by adding tiny particulates to thermoplastic polymers. Addition of clay causes changes in both the crystal phase and the microstructure of the nanocomposites. Objective – Assess the impact of clay nanoparticles on the structure and properties of a semicrystalline polymer. The selected polymer, poly(vinylidene fluoride), is used by industry in electrical applications because of its ability for transduction of electrical energy to mechanical energy. A thermal method was used to study the melting behavior of nanocomposites ranging from 0 to 1 wt.% of clay (Organically Modified Silicate). Data from: B. Seyhan Ince-Gunduz, Robert Alpern, Debeshu Amare, Peggy Cebe, Jennifer Crawford, Breanna Dolan, Stacey Jones, Ryan Kobylarz, and Matthew Reveley.Mater. Res. Soc. Symp. Proc., Vol. 949, 2007, Materials Research Society, 0949-C03-05. Names of undergraduates are underlined. Figure – Thermal analysis of nanocomposites as a function of clay composition shows a transition in the melting endotherm, from the non-polar alpha crystal phase to polar beta phase, as clay content increases.

(G) and Rochester Institute of Technology (RIT), spent six weeks at Tufts performing research in the laboratory of Prof. Peggy Cebe. a.) Makini Diaz (RIT) loads the scanning calorimeter; b.) Front row, interns: Abiodun Odunlami (RIT), Taiyabah Naeem (G), Makini Diaz (RIT), and Stephen Persinger (RIT); Second row: Prof. Roger Tobin, ASL Interpreter Wendy Jehlen, Teaching Assistant Seyhan Ince-Gunduz, ASL Interpreter Francine Graff-James, and Prof. Peggy Cebe. Front row L-R signs “PB-NC-20-07”: c.) Abiodun Odunlami (RIT) places a sample in the thermogravimetric analyzer; d.) Prof. Peggy Cebe was selected as 2006 recipient of the Tufts Faculty or Staff Multicultural.Service Award for providing research opportunities for the deaf and hard of hearing, and is congratulated by Prof. Dave Garman, Awards Committee chair.
