“…Due to properties such as self-cleaning, corrosion resistance, anti-icing and drag reduction, artificial superhydrophobic surfaces have received significant attention in the last few years [23][24][25][26][27][28][29]. The nanosecond pulsed laser ablation process has been recently used to create such surfaces.…”

“…Highly hydrophobic polymers can also be produced using this pattern [8] that could be used for antiwetting, anti-fogging, or anti-frosting applications. The formation of honeycomb surface patterns can be achieved using surface modification techniques such as lithography [9], laser ablation/ patterning [10], and imprinting [11]. Self-assembly of polymers at certain conditions which results in the formation of honeycomb patterns, commonly known as the breath figure method, has also been demonstrated in previous literature [12].…”

This work presents the effect of drying temperature on the formation of poly(vinyl chloride) (PVC) honeycomb microstructures formed by the breath figure technique. Results revealed the self-assembly of honeycomb patterns with small cell diameter and thick cell walls dried at room temperature. An increase in cell diameter and a decrease in wall thickness were observed as drying temperature was increased up to 70 ◦C while no formation of patterns was noted at temperatures greater than or equal to 80 ◦C. The presence of honeycomb patterns consequently enhanced the static water contact angle of the PVC layer. Electrowetting experiments revealed more pronounced reduction in the water contact angle on honeycomb-structured PVC compared to a flat PVC layer at any given applied voltage. A proof-of-concept on the feasibility of the honeycomb structures to trap microparticles by electrically-driven droplet actuationwas further demonstrated. Corresponding SEM images confirmed the entrapment of microparticles in the honeycomb cells and walls after the electrowetting experiment. These results offer new and facile strategies for tuning the morphological properties of polymeric honeycomb microstructures and its possible application in microparticle trapping and sensing.

To minimise potential damage and crack on glass induced by direct laser patterning, this study employed a cost-effective laser marker for the rapid ablation of nickel (Ni)-coated glass substrates to fabricate super-hydrophilic micro-nanostructures. Most of laser energy was consumed by ablating Ni film with minimal deposited on glass, leading to shallow micron structure to support the nanostructure. The investigation systematically explored the influence of Ni thickness and laser scan hatch distance on the resultant properties of the treated glass by scanning electron microscope (SEM), atomic force microscope (AFM), confocal microscope, X-ray photoelectron spectroscopy (XPS), gonoimeter, spectrophotometer and real-time assessments of anti-fogging and self-cleaning performance. The treated glass surface exhibited a hierarchical micro-nanostructure featuring a quasi-periodical hillock-hollow micron structure and widely distributed nanoparticles. This unique surface structure yielded an exceptionally low contact angle of 0°, exhibiting remarkable self-cleaning and antifogging capabilities that persisted for over 9 months without apparent degradation. Such durable exceptional self-cleaning and anti-fog performance was rarely been reported in the literature and was attributed to the stable micro-nanostructure and robust chemical bondings present on the surface, showcasing significant potential for widespread commercial applications.
