181. The Dynamics of Confined Polycarbonate Chains Probed with Incoherent Neutron Scattering
Published: 1/1/2001
Authors: Christopher L Soles, Jack F Douglas, Robert M Dimeo
Abstract: The mean-square atomic displacement of thin (1015 to 75 ) polycarbonate films supported on Si wafers is measured using incoherent elastic neutron scattering. The value of is determined by fitting the scattering intensity data to the D ...

182. Determination of the Dielectric Constant of Nanoparticles. I. Dielectric Measurements of Buckminsterfullerene Solutions
Published: 11/1/2000
Authors: Chad R Snyder, Jack F Douglas
Abstract: The static dielectric constant {epsilon} of buckminsterfullerene C^d60^ particles is determined in cis-decalin, toluene, and 1,2-dichlorobenzene using continuum models for spherical and sherical shell inclusions. The value for {epsilon} for isolated ...

183. Modification of the Phase Stability of Polymer Blends by Fillers
Published: 11/1/2000
Authors: Alamgir Karim, D W. Liu, Jack F Douglas, A Nakatani, Eric J. Amis
Abstract: We investigate the influence of surface modified filler particles on the phase stability of a model blend of polystyrene (PS) and polybutadiene (PB). The upper critical solution cloud point curve of PS/PB is destabilized (upward shift of critical te ...

184. Atomic Force Microscopy Studies of Phase Ordering in Polymer Blends and Clay-Filled Systems
Published: 8/1/2000
Authors: V Ferreiro, Jack F Douglas, Alamgir Karim, G Coulon
Abstract: Many industrial applications require a control of the morphology of thin polymer films. The morphology of thin polymer films depends on many factors : method of formation, tendency of film components to mix or dewet, the crystallization of film comp ...

185. Lattice Model of Living Polymerization. III. Evidence for Particle Clustering From Phase Separation Properties and Rounding of the Dynamical Clustering Transition
Published: 7/1/2000
Authors: J Dudowicz, Karl Freed, Jack F Douglas
Abstract: Equilibrium polymerization is studied here as a prototype for clustering transitions that commonly occur in systems of interacting particles at equilibrium. These transitions are often difficult to locate because of transition rounding associated wit ...

186. Preparation and Characterization of Polymer/Dendrimer Blends: Final Report, March 2000
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6506
Published: 3/1/2000
Authors: Eric J. Amis, Barry J. Bauer, A Topp, F Groehn, T J. Prosa, B D Viers, Da-Wei Liu, K A Barnes, C L. Jackson, G Nisato, Alamgir Karim, Jack F Douglas
Abstract: This report is a summary of the results of measurement and characterization on dendritically branched polymers that was done under Army Research Office Grant contract 35109-CH. This summary encompasses 3 previous NISTIR's for consecutive 12 month per ...

187. Determination of the Dielectric Constant of Nanoparticles. 1. Dielectric Measurements of Buckminsterfullerene Solutions
Published: 1/1/2000
Authors: Chad R Snyder, Jack F Douglas

188. Influence of Generation Number on the Dewetting of Hypergraft Poly(2-Ethyl-2-Oxazoline) Films
Published: 1/1/2000
Authors: K A Barnes, Jack F Douglas, D W. Liu, B B Bauer, Eric J. Amis, Alamgir Karim

189. Lattice Model of Living Polymerization. II: Interplay Between Polymerization and Phase Stability
Published: 1/1/2000
Authors: J Dudowicz, Karl Freed, Jack F Douglas
Abstract: Representative spinodal curves and polymerization lines for the equilibrium polymerization of linear polymers in a solvent have been calculated using aFlory-Huggins type mean-field theory. The calculations are primarily restricted to systems that pol ...

190. Polymer-Surface Interactions in Nanofilled Polymers
Published: 1/1/2000
Authors: Alamgir Karim, Jack F Douglas
Abstract: An understanding of the influence of polymer-surface interactions on the interfacial properties of nanoparticle fillers in polymer matrices is critical for applications of nanoparticle filled polymer materials. The infuence of nanoparticle-surace in ...
