INVESTIGATION OF NANODISPERSION IN POLYSTYRENE -MONTMORILLONITE NANOCOMPOSITES BY SOLID STATE NMR

December 15, 2003
Author(s)
S Bourbigot, Jeffrey W. Gilman, David L. VanderHart, W H. Awad, Rick D. Davis, A B. Morgan, C A. Wilkie
Nanocomposites result from combinations of materials with vastly different properties at the nanometer scale. These materials exhibit many unique properties, such as improved thermal stability, reduced flammability, and improved mechanical properties. Many

High Throughput Methods for Polymer Nanocomposites Research: Extrusion, Nmr Characterization and Flammability Property Screening.

November 1, 2003
Author(s)
Jeffrey W. Gilman, S Bourbigot, John R. Shields, Marc R. Nyden, Takashi Kashiwagi, Rick D. Davis, David L. VanderHart, W Demory, C A. Wilkie, A B. Morgan, J R. Harris, R Lyon
Several, recent, revolutionary advances in combinatorial (or high throughput, HT) polymer science have appeared in the literature, which significantly accelerate the rate of data generation. Although these new HT approaches may in part have been inspired

Effects of Melt-Processing Conditions on the Quality of Poly(ethylene terephthalate) Montmorillonite Clay Nanocomposites

December 1, 2002
Author(s)
Cher H. Davis, L J. Mathias, Jeffrey W. Gilman, D Schiraldi, Paul C. Trulove, T X. Suttos, H X. DeLong
The effects of melt intercalation processing conditons on the quality of poly(ethylene terephthalate) montmorillonite clay nanocomposites have been investigated by thermal gravametric analysis (TGA), X-ray diffraction XRD), and transmission electronic

Polymer/Layered Silicate Nanocomposites from Thermally Stable Trialkylimidazolium-Treated Montmorillonite.

December 1, 2002
Author(s)
Jeffrey W. Gilman, W H. Awad, Rick D. Davis, John R. Shields, Richard H. Harris Jr., C H. Davis, A B. Morgan, T E. Sutto, J H. Callahan, Paul C. Trulove, H DeLong
The limited thermal stability of alkylammonium cations intercalated into smectite minerals (e.g., montmorillonite, MMT) and the processing instability of some polymers [polyamide-6 (PA-6) and polystyrene (PS)] in the presence of nanodispersed MMT have

Development of High Throughput Methods for Polymer Nanocomposite Research

October 22, 2002
Author(s)
Jeffrey W. Gilman, Rick D. Davis, Marc R. Nyden, Takashi Kashiwagi, John R. Shields, W -. Demory
This chapter will present an overview of the development of two high throughput (HT) methods: 1) preparation of formulated polymer libraries using extrusion, 2) screening of flammability properties using flame spread measurements.

Polymer Layered-Silicate Nanocomposites from Thermally Stable Trialkyl-Imidazolium Treated Montmorillonite

August 16, 2002
Author(s)
Jeffrey W. Gilman, W H. Awad, Rick D. Davis, Cher H. Davis, John R. Shields, T E. Sutto, Richard H. Harris Jr., A B. Morgan, J H. Callahan, Paul C. Trulove, Hugh C. De Long
The limited thermal stability of alkyl ammonium cations and the processing instability of some polymers (polyamide-6 (PA-6) and polystyrene (PS)) in the presence of nanodispersed montmorillonite (MMT) has motivated the development of improved organophillic
