Superhydrophobic surfaces on cotton textiles by complex coating of silica nanoparticles and hydrophobization
TL;DR: By the complex coating of amino and epoxy functionalized silica nanoparticles on epoxy-functionalized cotton textiles to generate a dual-size surface roughness, followed by hydrophobization with stearic acid, 1H,1H, 2H,2H-perfluorodecyltrichlorosilane, or their combination, superhydrophobic surfaces were prepared.

Protic Ionic Liquid-Based Hybrid Proton-Conducting Membranes for Anhydrous Proton Exchange Membrane Application
TL;DR: In this paper, a new type of proton-conducting hybrid membranes were prepared by in situ cross-linking of a mixture of polymerizable oils containing protic ionic liquids (PILs) and silica nanoparticles or mesoporous silica nanospheres.
