Resumen:
It is well known that microbiological spoilage in indoor surfaces has a negative impact on human health.Antimicrobial functionalized materials are intensely studied. The present work seeks the synthesis ofeco-friendly and cheap bioactive hybrid filler from diatomaceous earth (DE). The activation method usedproved to be efficient to enhance the amount of quaternary ammonium groups supported by DE whichwas corroborated by spectroscopic methods and the thermogravimetry analysis. Zeta potential measurementsreviled a bilayer arrangement of the ammonium groups on the functionalized solids and the bioassaysshowed their antimicrobial activity.
