Superhydrophobic conductive materials have received a great amount of interest due to their wide applications in oil–water separation, electrically driven smart surface, electromagnetic shielding, and body motion detection. Herein, a highly conductive superhydrophobic cotton cloth is prepared by a facile method. A layer of polydopamine/reduced graphene oxide (PDA/rGO) was first coated on the cotton fabric, and then copper nanoparticles were in situ grown on the prepared surface. After further modification with stearic acid (STA), the wettability of the cotton surface changed from superhydrophilic to superhydrophobic (water contact angle (WCA) = 153°). The electrical conductivity of the PDA/rGO/Cu/STA cotton is as high as 6769 S·m–1, while the stearic acid effectively protects Cu NPs from oxidation. As a result, the superhydrophobic PDA/rGO/Cu/STA cotton has shown excellent electrical stability and can be used in detecting human motions in both ambient and underwater conditions. The sensor can recognize human motion from air into water and other underwater activities (e.g., underwater bending, stretching, and ultrasound). This multifunctional cotton device can be used as an ideal sensor for underwater intelligent devices and provides a basis for further research.

“…As previously mentioned, the material used in our pilot experiment was pure silicon. Another material with a different surface energy could very well result in enhanced biofilm attachment [ 40 , 41 , 42 , 43 , 44 , 45 ]. Finally, in this study, we used patterned surfaces with heights of around 13–14 µm.…”

Fabrication of Microstructured Surface Topologies for the Promotion of Marine Bacteria Biofilm

Several marine bacteria of the Roseobacter group can inhibit other microorganisms and are especially antagonistic when growing in biofilms. This aptitude to naturally compete with other bacteria can reduce the need for antibiotics in large-scale aquaculture units, provided that their culture can be promoted and controlled. Micropatterned surfaces may facilitate and promote the biofilm formation of species from the Roseobacter group, due to the increased contact between the cells and the surface material. Our research goal is to fabricate biofilm-optimal micropatterned surfaces and investigate the relevant length scales for surface topographies that can promote the growth and biofilm formation of the Roseobacter group of bacteria. In a preliminary study, silicon surfaces comprising arrays of pillars and pits with different periodicities, diameters, and depths were produced by UV lithography and deep reactive ion etching (DRIE) on polished silicon wafers. The resulting surface microscale topologies were characterized via optical profilometry and scanning electron microscopy (SEM). Screening of the bacterial biofilm on the patterned surfaces was performed using green fluorescent staining (SYBR green I) and confocal laser scanning microscopy (CLSM). Our results indicate that there is a correlation between the surface morphology and the spatial organization of the bacterial biofilm.

“…Although replication roadmaps by use of nanoimprint lithography 11,12 and roll-to-roll processes exist, 14,32,33 large area master origination methods for the fabrication of plasmonic metasurfaces have not yet been demonstrated. When looking into the nanofabrication toolbox, 34 a number of bottom-up methodologies 35 such as block-copolymer nanolithography, [36][37][38][39][40][41] and colloidal lithography 42,43 may offer promising roadmaps for origination of large area plasmonic surfaces. In addition, depending on the light source used, interferometric lithography may also be a suitable candidate for the fabrication of large area nanoscale patterns, but this technique usually requires complicated custom made setups.…”
