In this study, we present a novel composite material based on commercially available polyurethane foams functionalized with colloidal superparamagnetic iron oxide nanoparticles and submicrometer polytetrafluoroethylene particles, which can efficiently separate oil from water. Untreated foam surfaces are inherently hydrophobic oleophobic, but they be rendered water-repellent oil-absorbing by solvent-free, electrostatic particle deposition technique. It was found that combined...
Abstract In this work is presented a new category of self-growing, fibrous, natural composite materials with controlled physical properties that can be produced in large quantities and over wide areas, based on mycelium, the main body fungi. Mycelia from two types edible, medicinal fungi, Ganoderma lucidum Pleurotus ostreatus , have been carefully cultivated, being fed by bio-substrates: cellulose cellulose/potato-dextrose, second easier to digest mycelium due presence simple sugars its...
We describe a technique to fabricate, for the first time, superoleophobic coatings by spray casting nanoparticle-polymer suspensions. The method involves use of ZnO nanoparticles blended with waterborne perfluoroacrylic polymer emulsion using cosolvents. Acetone is shown be an effective compatibilizing cosolvent produce self-assembling nanocomposite slurries that form hierarchical nanotextured morphology upon curing. Fabricated coating surface investigated environmental scanning electron...
Graphene is the first 2D crystal ever isolated by mankind. It consists of a single graphite layer, and its exceptional properties are revolutionizing material science. However, there still lack convenient mass-production methods to obtain defect-free monolayer graphene. In contrast, graphene nanoplatelets, hybrids between graphite, already industrially available. Such nanomaterials attractive, considering their planar structure, light weight, high aspect ratio, electrical conductivity, low...
A method to reduce the surface roughness of a spray-casted polyurethane/silica/fluoroacrylic superhydrophobic nanocomposite coating was demonstrated. By changing main slurry carrier fluid, fluoropolymer medium, pretreatment, and spray parameters, we achieved arithmetic values 8.7, 2.7, 1.6 μm on three test surfaces. The surfaces displayed performance with modest variations in skewness kurtosis. level is smoothest yet produced these spray-based techniques. These surfaces, along polished...
Abstract Mucoadhesion is an extremely important field of adhesion science and the comprehensive understanding modulation mucoadhesion can lead to lifesaving materials technologies. For instance, deadly cases COVID‐19 (SARS‐CoV‐2) cytokine storm are associated with viral overproduction mucus, which obstructs airways. Mucin key polymeric compound that known as a family high molecular weight, heavily glycosylated proteins in epithelial tissues. occur many different ways such receptor specific...
An experimental study is presented on contact angle dynamics during spreading/recoiling of mm-sized water droplets impacting orthogonally various surfaces with data. Application hydrodynamic theory indicates that in the slow stage forced spreading slip length and microscopic should be line velocity dependent. The performs well kinematic (fast) spreading, which solid/liquid interactions are weak. molecular kinetic yields physically reasonable wetting parameters, which, however, vary impact...
Rapid advances in modern electronics place ever-accelerating demands on innovation towards more robust and versatile functional components. In the flexible domain, novel material solutions often involve creative uses of common materials to reduce cost, while maintaining uncompromised performance. Here we combine a commercially available paraffin wax-polyolefin thermoplastic blend (elastomer matrix binder) with bulk-produced carbon nanofibres (charge percolation network for electron...
Bioplastics with a wide range of mechanical properties were directly obtained from industrially processed edible vegetable and cereal wastes. As model systems, we present bioplastics synthesized wastes parsley spinach stems, rice hulls, cocoa pod husks by digesting in trifluoroacetic acid (TFA), casting, evaporation. In this way, amorphous cellulose-based plastics are formed. Moreover, many other natural elements these plants carried over into the rendering them exceptional thermo-physical...
Due to its potential in water-repelling applications, the impact and rebound dynamics of a water drop impinging perpendicular horizontal superhydrophobic surface have undergone extensive study. However, drops tend strike at an angle applications. In such cases, physics governing effects oblique are not well studied or understood. Therefore, objective this study was conduct experiment investigate various liquid viscosities, isothermal environment, on nanocomposite normal conditions (tilted...
Transparent liquid repellent coatings with exceptional wear and abrasion resistance are very demanding to fabricate. The most important reason for this is the fact that majority of transparent have so far been fabricated by nanoparticle assembly on surfaces in form films. These films or demonstrate relatively poor substrate adhesion rubbing induced compared polymer-based hydrophobic coatings. However, recent advances reported literature indicate considerable progress has now made towards...
A powerful replica molding methodology to transfer on-demand functional topographies the surface of bacterial cellulose nanofiber textures is presented. With this method, termed guided assembly-based biolithography (GAB), a surface-structured polydimethylsiloxane (PDMS) mold introduced at gas-liquid interface an Acetobacter xylinum culture. Upon fermentation, generated nanofibers are assembled in three-dimensional network reproducing geometric shape imposed by mold. Additionally, GAB yields...
Abstract Stretchable capacitive devices are instrumental for new‐generation multifunctional haptic technologies particularly suited soft robotics and electronic skin applications. A majority of elongating electronics still rely on silicone building or sensors by multiple‐step replication. In this study, fabrication a reliable parallel‐plate touch sensor, using nitrile rubber gloves as templates, is demonstrated. Spray coating both sides piece cut out glove with conductive polymer suspension...
Superhydrophobic materials hold an enormous potential in sectors as important aerospace, food industries, or biomedicine. Despite this great promise, the lack of environmentally friendly production methods and limited robustness remain two most pertinent barriers to scalability, large-area production, widespread use superhydrophobic materials. In work, highly robust silicone monoliths are produced through a scalable emulsion technique. It is first found that stable surfactantless...
