Abstract
Composite coatings were prepared from dealuminated zeolite Y and a hybrid polymer sol made from bis(triethoxysilyl)ethane. The zeolite pore accessibility and the microstructure were determined by gas sorption experiments and SEM measurements. The influence of different zeolite loadings was analyzed. In conclusion, the samples offered good pore accessibility if the zeolite content was at least 60% by weight. Such samples exhibited secondary pores in the macropore dimension. Furthermore, the obtained coatings offered wipe resistance and could easily be applied on flexible substrates. In addition, they showed reversible adsorption capacity of formaldehyde, which demonstrates their potential for application as an adsorptive layer for pollutants.
