Abstract
This work reports the functionalization of sugar maple (Acer saccharum) wood surfaces following their exposure to the jet of an atmospheric-pressure dielectric barrier discharge operated in either Ar or N2 with C3F8 (octafluoropropane) as the growth precursor for plasma-enhanced chemical vapour deposition. Analysis of the current–voltage characteristics (I–V) revealed a filamentary behaviour in all conditions. While more intense current peaks were observed after addition of C3F8 in Ar, a decrease in the discharge current was seen in N2/C3F8 plasmas. Optical emission spectroscopy showed the apparition of a CF2 + continuum and CF2 rovibrational bands between 225 and 350 nm with increasing applied voltage and precursor concentration in the Ar plasmas; a feature ascribed to the presence of plasma-generated C3F8 fragments. In such conditions, water contact angle (WCA) measurements indicated that freshly sanded wood samples became highly hydrophobic, with WCAs in the 140° range and excellent dimensional stability for a period of up to 125 days. X-ray photoelectron spectroscopy revealed that such behaviours result from the deposition of highly hydrophobic CF x groups on the surface. On the other hand, no increase in surface hydrophobicity was observed following exposure to the jet of N2/C3F8 plasmas, probably due to their much lower precursor fragmentation levels.
