Journal ArticleDOI
Polyurethane foam impregnated with lignin as a filler for the removal of crude oil from contaminated water.
Oseas Silva Santos,Mercês Coelho da Silva,Virginia Ribeiro da Silva,Wagner da Nova Mussel,Maria Irene Yoshida +4 more
TL;DR: The results of reuse of the PUf-10 showed that oil removal efficiency remained greater than 95% after five consecutive cycles, and the ΔG° value of -4.4kJmol-1 indicated that crude oil adsorption process by PUF-10 was spontaneous.
Journal ArticleDOI
Polyurethane foams based on modified tung oil and reinforced with rice husk ash I: Synthesis and physical chemical characterization
Virginia Ribeiro da Silva,Virginia Ribeiro da Silva,Mirna Alejandra Mosiewicki,Maria Irene Yoshida,Mercês Coelho da Silva,Pablo Marcelo Stefani,Norma Esther Marcovich +6 more
TL;DR: A chemically modified tung oil was used as the main polyol component in the formulation of viscoelastic (low resilience) polyurethane foams in this article.
Journal ArticleDOI
Composites of rigid polyurethane foam and cellulose fiber residue
Mercês Coelho da Silva,Jacqueline A. Takahashi,Didier Chaussy,Mohamed Naceur Belgacem,Glaura G. Silva +4 more
TL;DR: In this paper, the influence of the cellulose fiber concentration on the structural, thermal, mechanical, and morphological properties of rigid polyurethane composite foams was investigated. But, the cellulosic fibrous industrial residue was rationally valorized as a filler, which yielded materials with mechanical resistance and a susceptibility to fungi in a wet environment.
Journal ArticleDOI
Polyurethane foams based on modified tung oil and reinforced with rice husk ash II: Mechanical characterization
Virginia Ribeiro da Silva,Virginia Ribeiro da Silva,Virginia Ribeiro da Silva,Mirna Alejandra Mosiewicki,Maria Irene Yoshida,Mercês Coelho da Silva,Pablo Marcelo Stefani,Norma Esther Marcovich +7 more
TL;DR: In this article, a free-rise pouring method was used to sample polyurethane (PU) foams with rice husk ash (RHA) to characterize their density, compression and dynamic mechanical behavior.
Journal ArticleDOI
Characterization of three non-product materials from a bleached eucalyptus kraft pulp mill, in view of valorising them as a source of cellulose fibres
Mercês Coelho da Silva,O. R. Lopes,Jorge Luiz Colodette,A.O. Porto,Jacques Rieumont,Didier Chaussy,Mohamed Naceur Belgacem,Glaura G. Silva +7 more
TL;DR: In this paper, the structural, thermal, and morphological properties of bleached eucalyptus kraft pulp were analyzed using Fourier transform infrared spectroscopy (FTIR), energy dispersion spectrometry (EDS), X-ray diffraction (XRD), thermogravimetry (TG), temperature modulated differential scanning calorimetry(TMDSC), and scanning electron microscopy (SEM).
