Abstract
In our current study non-woven materials such as
polypropylene (PP) and polyester (PES), used in
filtration application, were modified in terms of surface
properties by using hybrid coatings synthesised by using
sol-gel method. The hybrid coatings consisted of
organically modified silanes with fluorocarbon
functionality in order to increase the hydrophobicity of
the non-woven surfaces. Furthermore, superhydrophobic
property was aimed to obtain by mixing silica (SiO2)
nanoparticles into the coating matrix. Surface chemistry
and topography of the coated specimens were characterised
by using FTIR, AFM and SEM methods. The water contact
angle measurements were used to detect the
hydrophobicity. It was revealed that the hybrid coating
with SiO2 nanoparticles increased the initial water
contact angle from 117o up to 140o for PP and
respectively from 87o up to 126o for PES non-woven.
