Biomimetic Polychrome Rubberized Fabric Constructed by Nonfluorinated Multiscale Hierarchical Superhydrophobic Latex Pigments.

Polychrome rubberized fabric was successfully prepared by assembling of nonfluorinated superhydrophobic latex pigments (SLPs) on resin-coated fabric, exhibiting superior water repellency and hue controllability. The SLPs with micro-nano multiscale rough structure were constructed by thermal-initiated polymerization of absorbed polymeric reactants in the cavity of hollow microreactors, as well as simultaneous capping of hydrophobic nanocomplexes and nanoscale inorganic pigments on the shell of the reactors. The hue of SLPs could be regulated by mixed color effect between the conjugated imine yellowing produced from hierarchical structure formation and added inorganic pigments. The prepared nonfluorinated polychrome superhydrophobic rubberized fabric (SRF) as low-hazard materials could be readily adhered on various textured substrates regardless of their size, shape, or composition, endowing the underlying substrates with durable and stable self-cleaning capacity. By virtue of the high adhesive effect of the organic resin, the SRF performed excellent mechanical durability to withstand the high-intensity abrasion damages and peeling tests. We believe that the SLPs with controllable hue and the polychrome SRF are conducive to reducing the cost and relieving the pressure from environmental governance, which have a good prospective academy and industry covering coating, pigments, and technical textiles.
