“…Among them, silica (SiO 2 ) received a particularly high attention as it showed great versatility in terms of properties, usage, and application methods. A first use for silica was as an additive in organic coatings to improve their mechanical properties [90,95] or to create a durable micro-/nanoscale architecture into the coating to reach superhydrophobicity [104]. Similar to the latter, it was also used to create a micro-/nanoscale architecture directly on the wood surface before hydrophobization with very low surface free energy compounds [104,106,111,113,117,118,120,126,128,130,132,133,151].…”
