Abstract

Abstract Fibrous clay mineral could be used to fabricate hydrophobic and superhydrophobic coatings, owing to the easily designed surface micro-nanoscale roughness and porous surfaces. Here, polydimethylsiloxane-palygorskite (PDMS-Pal) nanosponge-based coatings were fabricated via the UV-induced thiol−ene interfacial click reaction of the thiol modified palygorskite nanorods (Pal-SH) with polydimethylsiloxane diacrylate. The surface hydrophilic-hydrophobic reversal function of the PDMS-Pal nanosponges-based coatings was reported for the first time. The surface hydrophilic-hydrophobic reversal mechanism was proposed as the conformational transformation of the PDMS chains during treating with different solvents, revealed by SEM and XPS analysis. Such understanding is expected to design functional fibrous clay-based nanosponges for various applications.
