11. Multi-Walled Carbon Nanotube Layer-by-Layer Coatings With a Novel Trilayer Structure to Reduce Foam Flammability
Published: 10/29/2013
Authors: Rick D Davis, Yeon Seok Kim, Amanda A Cain, Jaime C. Grunlan
Abstract: The research presented here is the first report of fabricating multi-walled carbon nanotube (MWCNT) based thin coatings on polyurethane foam (PUF) using Layer-by-Layer assembly, and using MWCNTs to reduce the flammability of PUF. The (440.6 ± 47.1) ...

12. Evaluating Fire Blocking Performance of Barrier Fabrics
Published: 10/15/2013
Authors: Shonali Nazare, William M Pitts, Shaun M. Flynn, John R Shields, Rick D Davis
Abstract: The purpose of fire blocking barrier materials is to reduce the flammability of soft furnishings ( mattresses and upholstered furniture) by preventing or delaying direct flame impingement from open flames and/or heat transfer from smoldering igniti ...

13. Controlling Foam Flammability and Mechanical Behavior by Tailoring the Composition of Clay-Based Multilayer Nanocoatings
Published: 9/23/2013
Authors: Yu-Chin Li, Yeon Seok Kim, John R Shields, Rick D Davis
Abstract: This is the most comprehensive evaluation of Layer-by-Layer (LbL) coatings intended to reduce the flammability of polymeric materials. Through a systematic variation of the coating recipe, an ideal combination of the coating attributes was ide ...

14. Nanoparticles in Flame-Retardant Coatings for Flexible Polyurethane Foams: Effects on Flammability and Nanoparticle Release
Published: 5/15/2013
Authors: Mauro Zammarano, Rick D Davis, Yeon Seok Kim, Richard H. Harris Jr., Marc R. Nyden, Jeffrey W Gilman, Nasir M. Uddin
Abstract: Nanoparticles can effectively reduce polymer flammability; however, the impact of nanoparticles on environmental and health safety is still unclear. The purpose of this study is twofold: (1) to develop and investigate the effect of nanoparticle-rich- ...

15. Impact of Test and Foam Design on Smoldering
Series: Technical Note (NIST TN)
Report Number: 1799
Published: 5/14/2013
Authors: Mauro Zammarano, Szabolcs Matko, Rick D Davis
Abstract: Smoldering propensity of fabrics used in upholstered furniture can be assessed using foam mockups according to the CPSC proposed regulation. This approach requires a polyurethane flexible foam with reproducible and well- characterized smoldering ...

16. Guidelines for Evaluating Fire Blocking Barrier Fabrics
Series: Technical Note (NIST TN)
Report Number: 1798
Published: 4/18/2013
Authors: Shonali Nazare, William M Pitts, Shaun M. Flynn, Rick D Davis, John R Shields
Abstract: This document provides guidelines to quantify fire performance properties of fire blocking barrier materials used in soft furnishings. In an attempt to enable a priori selection of fire barrier materials such that the final upholstered product ...

17. Protective performance of environmentally stressed fabrics containing melamine fiber blends
Published: 1/12/2013
Authors: Shonali Nazare, Shaun M. Flynn, Rick D Davis, Joannie W Chin
Abstract: In this study, environmentally stressed OS fabrics containing melamine fiber blends were evaluated for thermal and mechanical properties that are critical to the protective performance of firefighter turnout gear. Environmental stress factors that a ...

18. Thermal and Burning Properties of Poly(lactic acid) Composites Using Cellulose-Based Intumescing Flame Retardants
Published: 12/21/2012
Authors: Douglas Matthew Fox, Srilatha Temburni, Melissa Novy, Laura Flynn, Mauro Zammarano, Yeon Seok Kim, Jeffrey W Gilman, Rick D Davis
Abstract: Poly(lactic acid) was flame retarded using cellulose-based intumescing flame retardants. Cellulose was an excellent carbon source in combination with ammonium polyphosphate (APP), exhibiting good thermal stabilities and UL-94 ratings of V-0. Nano ...

19. Smoldering in Flexible Polyurethane Foams: the Effect of Foam Morphology
Published: 12/18/2012
Authors: Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D Davis, Jeffrey W Gilman, Li Piin Sung, Douglas Matthew Fox, Shivani Navin Mehta
Abstract: Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion. Flexible polyurethane foams (PUF) are prone to smoldering due to their high air permeability, low density and high specific ...

20. Standard Operating Procedures for Smolder Ignition Testing of Upholstery Fabrics
Series: Technical Note (NIST TN)
Report Number: 1775
Published: 12/11/2012
Authors: Rick D Davis, Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer
Abstract: This manuscript describes a methodology to measure the influence of an upholstery cover fabric to promote smoldering mass loss of a small-scale mock-up. The primary test metric is total mock-up mass loss after 45 min exposure to the smoldering ...
