| Description |
Natural fibres (sisal) were treated with various coupling agents such as organosilane,
zirconate, titanate and N-substituted methacrylamide. The nature of the adsorbed chemical species on
the fibre surfaces was analysed by Fourier transform infrared microscopy (FT-IR). The presence of
precipitated oligomers on the surface was confirmed by the appearance of hydrogen-bonded carbonyl
group and unsaturation bands. The results showed an irregular physisorption/chemisorption of
coupling agents, their penetration beyond the surface, and a decrease in the hydrophilicity of fibres.
SEM and dynamic contact angle studies on the fibres supported these findings. FT-IR microscopy in
its re¯ectance mode was more effective in ascertaining the chemical nature and structure of adsorbed
layers onto sisal fibre surfaces compared with DRIFT and transmission spectroscopy. The difference
in the properties of untreated and chemically treated fibres has also been verified in the polymer
composites.
