Amine-functionalized porous silicas (aminosilicas) are incorporated into latex coatings, and the airborne aldehyde abatement abilities of the dried applied films are examined. The aminosilicas in the resulting dried films are uniformly dispersed inside the latex component, and they are demonstrated to be effective adsorbents for airborne aldehydes. The latex component does not hinder the adsorption capacities of the aminosilicas, with the adsorbed amounts being similar to those of the original aminosilica powders before incorporation into the latex. However, the adsorption rates are slowed after incorporation of the aminosilicas into the films, relative to that of the powder samples. Overall, the aminosilica-incorporated latex films are demonstrated to be effective aldehyde-abating materials.
