21. Heat release and structural collapse of flexible polyurethane foam
Published: 1/1/2010
Authors: Roland H. Kraemer, Mauro Zammarano, Gregory T Linteris, Ulf Wil Gedde, Jeffrey W Gilman
Abstract: Flexible polyurethane foam used in upholstered furniture remains one of the major fire hazards to date. The heat release rate of burning items made of foam depends strongly on the foam‰s physical behavior, notably its collapse to a burning liquid tha ...

Published: 3/17/2009
Authors: Kuldeep R Prasad, Roland Kramer, Nathan D Marsh, Marc R. Nyden, Thomas J. Ohlemiller, William M Pitts, Mauro Zammarano
Abstract: The NIST Fire Dynamics Simulator (FDS) is used extensively by the fire protection engineer for performance based design and forensic analysis. The equations of motion describing the gas phase are relatively well known and the approximations in the va ...

23. Preparation and Flame Resistance Properties of Revolutionary Self-Extinguishing Epoxy Nanocomposites Based on Layered Double Hydroxides
Published: 10/1/2005
Authors: Mauro Zammarano, Massimiliano Franceschi, S Bellayer, Jeffrey W Gilman, Sergio Meriani
Abstract: Layered double hydroxides/epoxy nanocomposites (LDHs/EP) were prepared from organo modified LDHs, a diglycidyl ether of bisphenol A monomer (DGEBA) and amine curing agents. The organomodified LDHs were obtained by ionic exchange of a magnesium-alumi ...

24. Delamination of Organo-Modified Layered Double Hydroxides in Polyamide 6 by Melt Processing
Published: Date unknown
Authors: Mauro Zammarano, S Bellayer, Jeffrey W Gilman, Massimiliano Franceschi, Frederick Beyer, Richard H. Harris Jr., Meriani Sergio
Abstract: Layered double hydroxide/polyamide 6 nanocomposites (LDH/PA6) were prepared from organo-modified LDH by melt processing. The anionic exchange capacity of LDH was varied in order to investigate its influence on the degree of exfoliation. LDH were disp ...

25. Effect of Carbon Nanofiber Network Formation on Flammability of Flexible Polyurethane Foams
Published: Date unknown
Authors: Mauro Zammarano, Roland H. Kraemer, Richard H. Harris Jr., Thomas J. Ohlemiller, John R Shields, Sameer Rahatekar, Jeffrey W Gilman
Abstract: Polyurethane flexible foams (PUFs) are used extensively as upholstery and bedding materials. Untreated PUFs are prone to rapid fire growth due to their low density and thermal conductivity. Furthermore, the low viscosity of the decomposition products ...

26. Flexible Polyurethane Foams Nanocomposites
Published: Date unknown
Authors: Mauro Zammarano, Roland H. Kraemer, Richard H. Harris Jr., Thomas J. Ohlemiller, Sameer Rahatekar, Jeffrey W Gilman
Abstract: Polyurethane flexible foams (PUFs) have a large market as upholstery and bedding cushioning material. There is an increasing demand for flame retarded grades in rail, plane and automotive transportation. Untreated PUFs are prone to rapid fire growth ...

27. Imidazolium Modified Clay Based ABS Nanocomposites: A Comparison Between Melt-Blending and Solution Sonication Processes
Published: Date unknown
Authors: M Modesti, S Besco, A Lorenzetti, Mauro Zammarano, V Causin, C Marega, Jeffrey W Gilman, D M Fox, Paul C Trulove, Hugh C De Long, P H Maupin
Abstract: Acrylonitrile-butadiene-styrene (ABS) nanocomposites containing imidazolium-modified montmorillonite have been prepared by melt-blending and solution-sonication in order to study the effects of processing on the morphology and properties of the polym ...

28. Ionic Liquids as Compatibilizers for the Preparation of Biopolymer Nanocomposites: Characterization Using Laser Scanning Confocal Microscopy
Published: Date unknown
Authors: Jeffrey W Gilman, P H Maupin, Mauro Zammarano, Paul C Trulove, D M Fox, H DeLong, Ph Dubois, M Murariu
Abstract: The process of dispersing ionic liquid modified montmorillonite in polylactide (PLA) using a twin-screw micro-compounder under different melt-compounding parameters was monitored using laser scanning confocal microscopy (LSCM). In addition the PLA-MM ...

29. Layered Double Hydroxides as Cation Exchange Materials
Published: Date unknown
Authors: Paul Braterman, Nandika A. D'Souza, Jeffrey W Gilman, Mickey C. Richardson, Laxmi Kumari Sahu, Mauro Zammarano
Abstract: Layered double hydroxides (LDH) are a class of materials formally related to brucite-like hydroxides by the incorporation of higher valent cations, such as Al(III). The layer charge is neutralized by the insertion of any of a large range of exchange ...

30. The Role of Oxidation in the Migration Mechanism of Layered Silicate in Polypropylene Nanocomposites
Published: Date unknown
Authors: Mauro Zammarano, Jeffrey W Gilman, Marc R. Nyden, Eli M Pearce, Menachem Lewin
Abstract: Polymer nanocomposites based on layered silicates (PLS) have attracted the interest of the scientific community for their outstanding combination of properties such as mechanical and chemical resistance, and reduced permeability and flammability. It ...
