Natural fiber-reinforced polymer for structural application
(2015-01-01)
The glued laminated lumber (glulam) beams technique is an efficient process for making sustainable use of wood. Fiber-reinforced polymers (FRPs) associated with glulam provide significant gains in terms of strength and ...
Thermally Promoted Elimination and Substitution Reactions in Poly(p-arylene vinylene) Precursor Polyelectrolytes
(American Chemical Society, 2000-06)
The thermal conversion of dialkylsulfonium polyelectrolyte precursor polymers 1b-e to poly(p-arylene vinylene)s was studied by direct pyrolysis mass spectrometry in order to elucidate the mechanism of the sulfonium elimination ...
Development and Characterization of Natural Rubber Latex and Polylactic Acid Membranes for Biomedical Application
(2020-01-01)
Natural rubber latex from the Hevea brasiliensis has been of great importance in areas such as medicine and bioengineering, due to its angiogenic and wound healing activity. However, the biodegradability of natural rubber ...
Modification and Characterization of Hemp and Sisal Fibers

Curaua fibers - The queen of the fibers
(2017-01-01)
Nowadays, the usage of natural resources is under worldwide growing interest. From this perspective, different renewable sources have been studied to replace man-made polymers or even improve the properties of current ...
ROMP-based biorenewable polymers of norbornene modified with triglycerides or esters from natural buriti oil
(Springer, 2019-10-01)
Two novel monomers, norbornenyl buriti olein (NBO) and norbornenyl buriti ester (NB-FAME), were synthesized by reactions of 5-norbornene-2-carboxylic acid with triglycerides and with methyl esters from buriti oil, respectively. ...
