For a 2-min TCMS-treated TMP, a decrease of the dispersive component of the surface energy from 38 to 14 mJ m−2 (at 40°C), and, at the same time, an increase of the Lewis acidic and Lewis basic characters were found. The surface of this sample, modified in a high extent, was similar to that of a bleached kraft pulp (<0.1 wt% of lignin) subjected to the same silanization process, which is suggested as being due, in both cases, to the formation of a methyl-silica coating on the fiber’s surface. The new silanized fibers obtained from cheap TMP can be used for the production of a new generation of biocomposites with a variety of matrices.12764887enginfo:eu-repo/semantics/openAccessjournal article10.1080/02773813.2018.1454961LignocelluloseChemical vapor depositionSilanizationSurface energyLewis acid-base characterInverse gas chromatographyLignocelluloseChemical vapor depositionSilanizationSurface energyLewis acid-base characterInverse gas chromatographyGeneral ChemistryGeneral Chemical EngineeringGeneral Materials Sciencehttp://www.scopus.com/inward/record.url?scp=85047953834&partnerID=8YFLogxK
