Bionic micro-nano-bump-structures with a good self-cleaning property: The growth of ZnO nanoarrays modified by polystyrene spheres

Porous Surface Films With Tunable Morphologies and Hydrophobic Properties Based on Block Copolymer Under the Effects of Thermal Annealing

“…The block copolymerization based on polystyrene with tert-butyl acrylate (tBA), has been reported previously (Coca et al, 1998; Beers et al, 1999; Teodorescu et al, 2000; Min et al, 2005; Pizarro et al, 2013, 2015; Yu et al, 2016), however block copolymers with dimethyl allylmalonate (DMM), and dimethyl itaconate (DMI) as specific monomers were used. To the best of our knowledge, block copolymers with DMM and DMI monomers have not yet been reported.…”

“…The surface wettability surface of materials is known to be mainly dependent on the geometrical structure and the chemical composition, with consequent practical applications (Wan et al, 2012; Sasmal et al, 2014; Cheng et al, 2015; Yu et al, 2016). A direct expression of the wettability of a surface is the water contact angle (WCA), which a water drop is placed on the film surface for WCA measurements.…”

Failure Mechanisms in Vertically Aligned Dense Nanowire Arrays

“…This work highlights the substantial role of interfacial mechanisms governing failure behavior of microsized nanowire structures. For devices where these mesoscale components have become increasing prevalent, such as tactile sensors, , novel memrisistors, and self-cleaning coatings, it is critical to characterize and explore the fundamental role of interfaces in structural failure for future generations of devices.…”

“…This work highlights the substantial role of interfacial mechanisms governing failure behavior of microsized nanowire structures. For devices where these mesoscale components have become increasing prevalent, such as tactile sensors, 11,12 novel memrisistors, 13 and self-cleaning coatings, 14 it is critical to characterize and explore the fundamental role of interfaces in structural failure for future generations of devices. We synthesize vertically oriented, micron-sized bundles of densely packed, 300 nm diameter ZnO nanowires and probe their deformation-to-failure behavior via in situ microcompression experiments.…”

Femtosecond laser generation of microbumps and nanojets on single and bilayer Cu/Ag thin films

“…[31][32][33][34][35][36][37][38][39][40][41][42][43] The latter surface structures can be replicated into ordered arrays by means of interference between multiple beams. 31,44 The surfaces with arrays of metallic and non-metallic microbumps have many potential technological applications due to their unique properties, such as superhydrophobicity, 45,46 self-cleaning, 47 and enhanced tribological performance, 48 as well as their active and nonlinear optical response. 49 While the generation of microbumps and nanojets has been reproduced in many studies, the mechanisms behind their formation are still being debated.…”
