Thedepositionof ball-milledPDMScan be facilitatedby brushingordrop-casting,enablinglarge-scaleapplications.Theresultingsurfacesfacilitatethe slidingof dropletsat angles<20°for liquidswith surfacetensionrangingfrom 22 to 73 mN/m.An importantapplicationfor publichealthis generatinganti-biofoulingcoatingson sanitaryware.For example,PDMS-graftedsurfacespreparedon a regular-sizetoiletbowlexhibita 105-fold decreasein theattachmentof bacteriafrom urine.Thesefindingshighlightthe significantpotentialof mechanochemicalprocessesfor the practicalpreparationof liquid-likesurfaces.enCC BY-NC-ND 4.0 Deed (Attribution-NonCommercial-NoDerivs 4.0 International)Liquid-likesurfaceSiliconeCoatingsAnti-biofoulingMechanochemistryArticle10.1021/acsami.3c113521944-8252
