Thermal and Burning Properties of Poly(lactic acid) Composites Using Cellulose-Based Intumescing Flame Retardants

December 21, 2012
Author(s)
Douglas M. Fox, Srilatha Temburni, Melissa Novy, Laura Flynn, Mauro Zammarano, Yeon S. Kim, Jeffrey W. Gilman, Rick D. Davis
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

Smoldering in Flexible Polyurethane Foams: the Effect of Foam Morphology

December 18, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D. Davis, Jeffrey W. Gilman, Li Piin Sung, Douglas M. Fox, Shivani N. Mehta
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 surface

RESONANCE ENERGY TRANSFER AS A TOOL FOR PROBING INTERFACE FORMATION IN NANOCOMPOSITES

June 24, 2012
Author(s)
Mauro Zammarano, Edward D. McCarthy, Douglas M. Fox, Paul H. Maupin, Li Piin Sung, Yeon S. Kim
One of the most enduring problems in the evolution of science and technology using nanoscale materials is the characterization of their morphology in macroscopic systems.1 This involves spatial and orientation distribution, which may be multimodal and

Char – Forming Behavior of Nanofibrillated Cellulose Treated with Glycidyl Phenyl POSS

April 15, 2012
Author(s)
Douglas M. Fox, Jieun Lee, Mauro Zammarano, Dimi Katsoulis, Donald V. Eldred, Luke Haverhals, Paul C. Trulove, Hugh C. De Long, Jeffrey W. Gilman
Cellulose-reinforced composites have received much attention due to their structural reinforcing, light weight, biodegradable, non-toxic, low cost and recyclable characteristics. However, the tendency for cellulose to aggregate and its poor dispersion in

Revealing the Interphase in Polymer Nanocomposites

March 16, 2011
Author(s)
Mauro Zammarano, Paul H. Maupin, Li Piin Sung, Jeffrey W. Gilman, Douglas M. Fox
Morphological characterization of polymer nanocomposites is a fundamental challenge that is complicated by multiple length scales. Here, we report a technique for high-throughput monitoring of interphase and dispersion in polymer nanocomposites based on

SUSTAINABLE FLAME RETARDANTS: BIO-DERIVED PRODUCTS AS INTUMESCING MATERIALS

February 2, 2011
Author(s)
Mauro Zammarano, Douglas M. Fox, Szabolcs Matko, Takashi Kashiwagi, Jeffrey W. Gilman, Rick D. Davis
Scientists are shifting their attention towards technology sustainability and sustainable materials, specifically in terms of energy and environmental impacts. The flame retardant community is also more concerned about these aspects. The recent banning of

Microencapsulated POSS in Cellulose Using 1-Ethyl-3-Methylimidazolium Acetate

October 10, 2010
Author(s)
Douglas M. Fox, Mauro Zammarano, Jeffrey W. Gilman
Polyhedral oligomeric silsesquioxane (POSS) and cellulose were reacted in the ionic liquid, 1-ethyl-3-methylimidazolium acetate (EmiAc). Side reactions between the EmiAc and each reactant were prevalent, but use of water as the coagulating solvent produced

POSS modified cellulose for improving flammability characteristics of polystyrene

April 2, 2010
Author(s)
Douglas M. Fox, Mauro Zammarano, Jeffrey W. Gilman, Jieun Lee, Eric Balsley, Erica Ford
Due to its strength, charring ability, and biodegradability, cellulose-based reinforced polymers have received considerable attention. However, its high polarity, large molecular size, and solvent resistivity, have often resulted in immiscible or
