Formaldehyde emissions
are nowadays trying to be reduced because of its atmospheric pollutant
character. Besides, it is encouraged the use of polymeric materials synthesized
from biomass wastes as row materials. For this reason, furan resins would be an
alternative to phenolic resins, where formaldehyde is replaced by furfural as a
reactant. Regarding, the addition of nanoparticles to the furan resin should
enhance their performance as metal coatings with good thermal and oxidative
resistance. The aim of this paper is to study the influence of the in-situ
addition of different type of nanoparticles on the chemical reactions involved
in the synthesis of a furan resin. From the viscosity measurements it was
observed that the addition of the nanoreinforcements led to a higher resin
reaction rate. Differences in the final chemical structure among the materials
were also observed by infrared spectroscopy analyses (FT-IR).
