Universal polysiloxane additives for self-cleaning surfaces

Four novel additives and 16 different compositions have been evaluated in a new study for their self-cleaning performance toward UV curable coatings. The prepared additives showed excellent water, vegetable oil and hexadecane repellencies.

Commercially feasible self-cleaning surfaces are highly desirable for various technological applications. However, the current approaches are challenging to scale up and often lack the desirable performance.

The synthesis of novel siloxane-based additives for the oversimple fabrication of surfaces with excellent self-cleaning properties is reported in the new study. These siloxane-based additives are synthesized by the free-radical polymerisation of methacryloxypropyl-terminated polydimethylsiloxane (PDMS) with tetrahydrofurfuryl acrylate (THFA) monomer at various compositions, and these additives were subsequently incorporated into UV curable coatings.

Four novel additives

In total, four novel additives and 16 different compositions are evaluated in the study for their water, oil, and hexadecane repellent properties, as well as for their anti-ink performance.
