Mussel‐Inspired Block Copolymer Lithography for Low Surface Energy Materials of Teflon, Graphene, and Gold

Abstract

Mussel-inspired interfacial engineering is synergistically integrated with block copolymer (BCP) lithography for the surface nanopatterning of low surface energy substrate materials, including, Teflon, graphene, and gold. The image shows the Teflon nanowires and their excellent superhydrophobicity.

High-performance nanopattern triboelectric generator by block copolymer lithography

“…Au film (100 nm) was deposited on the cleaned substrate by thermal evaporation and cleaned by an ultraviolet-ozone (UVO) treatment for 30 min. For the surface functionalization of a chemically inert Au layer for BCP patterning, graphene oxide thin layer was deposited at Au surface [37][38][39]. Graphene oxide thin film was spin-casted onto the Au surface from an aqueous dispersion.…”

“…5). A PDA-decorated PTFE separator was also invented by this group [112], and the PDA coating showed a significant improvement in the compatibility between surfaces even with low surface energy [113]. Moreover, the PDA-decorated separators exhibited excellent anti-oxidative and anti-thermal-shrinkage properties [110,114].…”

Current Approaches to Designing Nanomaterials Inspired by Mussel Adhesive Proteins

“…Surfaces coated with the composite macroparticles had a water contact angle as large as 160° (Figure 12.8d). Other low-energy surfaces have been prepared utilizing polydopamine as the anchoring group in combination with lithography techniques [166] or reducing silver nanoparticles onto a graphene surface [167].…”
