221. The Influence of Polymer-Polymer and Polymer-Surface Interactions on the Formation and Swelling of End-Grafted Polymer Layers
Jack F Douglas
Investigations at NIST on the influence of polymer-polymer excluded volume and polymer-surface interactions on the formation and swelling of end-grafted polymer layers are reviewed. Recent theoretical modeling of grafted layers having a low grafting ...
222. Thermal Degradation and Flammability Properties of Nanocomposites
Takashi Kashiwagi, A B. Morgan, Joseph M Antonucci, Richard H. Harris Jr., E A Grulke, J NA Hilding, Jack F Douglas
Thermal degradation and flammability properties of the two types of nanocomposites with nanosilica and carbon nanotubes were studied. PMMA, poly(metheyl methacrylate), nanocomposites were made by in situ radical polymerization of MMA, methylmethacryl ...
223. Tuning the Fragility of Polymer Melts With Antiplasticizer Additives
Robert A Riggleman, K Yoshimoto, Jack F Douglas, J J de Pablo
Using molecular dynamics simulations, we have developed and analyzed a model that exhibits antiplasticization behavior by decreasing the glass transition temperature, increasing the density of the system below the glass transition temperature of the ...
224. Wetting-Dewetting Transition Line in Thin Polystyrene Films
K M. Ashley, D T Raghavan, Jack F Douglas, Alamgir Karim
Thin polymeric films are increasingly being utilized in diverse technological applications and it is crucial to have a reliable method to characterize the stability of these films against dewetting. The parameter space that influences the dewetting ...
