51. Use of Integrating Spheres as Uniform Sources for Accelerated UV Weathering of Advanced Materials
Joannie W Chin, Jonathan W. (Jonathan W.) Martin, Walter Eric Byrd, E Embree
The primary method for obtaining laboratory weathering data for a wide range of commercial polymer products including coatings, textiles, elastomers, plastics and polymeric composites is through the use of ultraviolet radiation exposure chambers (UV ...
52. Validation of the Receprocity Law for Coating Photodegradation
Joannie W Chin, Tinh Nguyen, Jonathan W. (Jonathan W.) Martin, E Byrd
Accelerating the photodegradation of commerical polymeric materials has great practical importance in the weathering community. However, questions exist as to whether high radiant flux exposure results cn be extrapolated to in-service exposure levels ...
53. Water based Polyurethane Graphene Oxide Nanocomposites
Coralie Bernard, Tinh Nguyen, Bastien T. Pellegrin, Mat Celina, Alexander J. Shapiro, Deborah L Stanley, Kar Tean Tan, Sungjin Park, R. S. Ruoff, Joannie W Chin
Graphene oxides are potentially a new class of nanomaterial to enhance multifunctional properties of polymers because of their remarkable thermal conductivity, mechanical strength, and more importantly, low cost. The graphene oxides, produced by exfo ...
