Highly porous PS/DVB monoliths were prepared by polymerisation of the continuous phase of a high internal phase emulsion. To improve the mechanical properties of these brittle materials, the monoliths were placed in the presence of FA vapours and the adsorbed monomer was polymerised by heating to create a coating onto the matrix surface. The influence of the coating on the material porous structure was investigated by SEM, mercury intrusion porosimetry and nitrogen adsorption/desorption analyses. The progressive increase in PFA content induced a porosity decrease and a modification of the pore distribution. The more pronounced effect of the coating was the remarkable improvement in the material mechanical properties.
