| Abstract: | The chemistry and wetting behaviour of surface densified wood were investigated using FT-IR spectroscopy and contact angle
analyses. Furthermore, set-recovery of the surface under conditions of fluctuating humidity was measured and quantitative
microscopy analyses were undertaken. FT-IR indicated that no significant chemical changes took place during the densification
process. However, the wettability of the densified surfaces was significantly lower than unmodified surfaces. Following several
high humidity-oven dry cycles, it was found that this densification process was almost completely reversible, i.e., there
was full set-recovery. |
