Viscosity, pH, and moisture effect in the porosity of poly(furfuryl alcohol)
(2013-01-01)
The poly(furfuryl alcohol) is highly indicated to obtain advanced carbonaceous materials due mainly to its good carbon yield (around 50%) and a controllable cure reaction. In the processing of some carbonaceous materials, ...
