A Fluffy All-Siloxane Bottlebrush Architecture for Liquid-like Slippery Surfaces

Slippery surfaces, known for their low adhesive properties and efficient self-cleaning capabilities, have gained significant attention. However, the existing liquid-like slippery surfaces are limited to linear molecular structures, which hinders the new design and functionalization of the slippery surfaces.

In this study, we present a novel fluffy all-siloxane bottlebrush molecular architecture that enables the construction of liquid-like slippery surfaces through a simple sequential architecting method. This unique structure, consisting of soft polysiloxanes as both backbones and side chains, enhances surface slipperiness via the in-situ condensation of dimethoxy-silanes and subsequent hydrosilylation reaction onto the substrate.
