61. Improved Thermal Stability Of Crown Ether And Imidazolium Treatments for Flame Retardant Polymer Layered-Silicate Nanocomposites
Published: 2/6/2002
Authors: Jeffrey W Gilman, Cher H. Davis, Rick D Davis, W H. Awad, A B. Morgan, Paul C Trulove, Hugh C De Long, T E Sutto, L J Mathias, D Schiraldi
Abstract: The thermal stability of the organic treatment present on a layered silicate is of utmost importance in preparing a polymer-layered silicate (clay) nanocomposite by melt processing methods. Specifically, the organic treatment must not decompose at te ...

62. Recent Advances in Flame Retardant Polymer Nanocomposites
Published: 1/22/2001
Authors: Jeffrey W Gilman, Takashi Kashiwagi, A B. Morgan, Richard H. Harris Jr., L D. Brassell, W H. Awad, Rick D Davis, L Chyall, T E Sutto, Paul C Trulove, H DeLong
Abstract: A new approach to address the ever increasing demand for higher performance flame retarded products has recently focused on use of mica-type clays nano-dispersed in commodity polymers. These "nanocomposites" exhibit the unusual combination of reduce ...

63. Development of High Throughput Methods for Polymer Flammability Property Characterization
Published: Date unknown
Authors: Jeffrey W Gilman, Rick D Davis, John R Shields, D Wentz, L D. Brassell, A B Morgan, R Lyon, J E Zanetto
Abstract: Recently we have developed several new high throughput (HT) methods to quantitatively evaluate the flammability of flame retarded (FR) polymers. The most recent results are due to the efforts of the High Throughput Methods for Materials Flammability ...

64. Dielectric Spectroscopy During Extrusion Processing of Polyamide-6 Nanocomposites
Published: Date unknown
Authors: Rick D Davis, Anthony J. Bur, Jeffrey W Gilman, Young Jong Lee, P R Start
Abstract: During extrusion processing dielectric spectroscopy was conducted on polyamide-6 (PA6) and organoclay/polyamide-6 nanocomposites. Off-line curve fitting of the on-line dielectric data generated dielectric dispersion parameters that appear sensitive ...

65. High Throughput Methods for Rapidly Developing Additive Filled Polymers
Published: Date unknown
Authors: Rick D Davis, Jeffrey W Gilman, Marc R. Nyden, John R Shields, Richard H. Harris Jr., W Demory
Abstract: The high throughput mindset has been our approach to rapidly synthesize, characterize, and analyze additive filled polymers. For example, rather than taking a week to extrude polystyrene strands with 0% to 10% integer amounts of organically modified ...

66. High-Throughput Methods for Flammability Screening of Multicomponent Polymer Blends and Nanocomposites
Published: Date unknown
Authors: Marc R. Nyden, Jeffrey W Gilman, Rick D Davis, John R Shields
Abstract: An overview of the research directed at the development and application of high-throughput methods for multi-component polymer blends and nanocomposites that is currently underway in the Building and Fire Research Laboratory is presented.

67. Measurements of the Photolytic Breakdown of Decabromodiphenyl Ether in Plastics
Published: Date unknown
Authors: Marc R. Nyden, Rick D Davis, Christopher C White, H M. Stapleton, Nathan G. Dodder
Abstract: In this talk, we report the product distributions and decomposition rates of DecaBDE when it is incapsulated in a common plastic, high impact polystyrene, and irradiated under controlled conditions using a calibrated source. The objective is to gain ...

68. Use of Optical Probes and Laser Scanning Confocal Fluorescence Microscopy for High Throughput Characterization of Dispersion in Polymer Layered Silicate Nanocomposites
Published: Date unknown
Authors: Jeffrey W Gilman, Rick D Davis, S Bellayer, P H Maupin, Raghavan Dharmara, Joseph Langat, S Bourbigot, X Flambard, D M Fox, Paul C Trulove, Hugh C De Long
Abstract: The development of high throughput methods for studying polymer layered silicate nanocomposites (PLSN) is motivated by the fact that these materials represent a multiple parameter problem. We have developed a HT platform for the study of thermoplasti ...
