Environmental Friendly Flame Resistant Coatings for Soft Furnishing

May 1, 2019
Author(s)
Yeon S. Kim, Yu-Chin Li, John R. Shields, Rick D. Davis
Pending flammability regulations and scrutinizing of the environment and health consequences of fire retardants is creating opportunities for novel and “greener” technologies to reduce the flammability of residential furniture. This presentation will

Development of High Throughput Methods for Polymer Flammability Property Characterization

February 19, 2017
Author(s)
Jeffrey W. Gilman, Rick D. Davis, John R. Shields, D Wentz, L D. Brassell, A B. Morgan, R Lyon, J E. Zanetto
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

Dielectric Spectroscopy During Extrusion Processing of Polyamide-6 Nanocomposites

February 19, 2017
Author(s)
Rick D. Davis, Anthony J. Bur, Jeffrey W. Gilman, Young Jong Lee, P R. Start
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 to

High Throughput Methods for Rapidly Developing Additive Filled Polymers

February 19, 2017
Author(s)
Rick D. Davis, Jeffrey W. Gilman, Marc R. Nyden, John R. Shields, Richard H. Harris Jr., W Demory
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 clay

Measurements of the Photolytic Breakdown of Decabromodiphenyl Ether in Plastics

February 19, 2017
Author(s)
Marc R. Nyden, Rick D. Davis, Christopher C. White, H M. Stapleton, Nathan G. Dodder
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

Use of Optical Probes and Laser Scanning Confocal Fluorescence Microscopy for High Throughput Characterization of Dispersion in Polymer Layered Silicate Nanocomposites

February 19, 2017
Author(s)
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
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 thermoplastic

Epoxy Composites Using Wood Pulp Components as Fillers

November 30, 2016
Author(s)
Douglas M. Fox, Noy Kaufman, Jeremiah W. Woodcock, Jeffrey W. Gilman, John R. Shields, Rick D. Davis, Szabolcs Matko, Mauro Zammarano, Chelsea S. Davis
The components of wood, especially lignin and cellulose, have great potential for improving the properties of polymer composites. In this chapter, we discuss some of the latest developments from our lab on incorporating wood based materials into epoxy

Smoldering and Flame Resistant Textiles via Conformal Barrier Formation

November 2, 2016
Author(s)
Mauro Zammarano, Shonali Nazare, John R. Shields, Kathleen M. Hoffman, Rick D. Davis
A durable and flexible silicone-based backcoating (halogen and formaldehyde free) is applied to the backside of an otherwise smoldering-prone and flammable fabric. When exposed to fire, cyclic siloxanes (produced by thermal decomposition of the backcoating
