A “PDMS-in-water” emulsion approach is developed to construct a mechanochemically robust superhydrophobic cotton fabric with intelligent self-healing nature against intensive mechanical damage.
Abstract Effective and easy regulation of hydrogel surface properties without changing the overall chemical composition is important for their diverse applications but remains challenging to achieve. We report a generalizable strategy reconfigure networks based on hydrogel–substrate interface dynamics manipulation wettability bioadhesion. show that grafting hydrophobic yet flexible polymeric chains mold substrates can significantly elevate content polymer backbones reduce presence polar...
Abstract Flexible actuation of droplets is crucial for biomedical and industrial applications. Hence, various approaches using optical, electrical, magnetic forces have been exploited to actuate droplets. For broad applicability, an ideal approach should be programmable able arbitrary size composition. Here we present “additive-free” method programmably manipulate water, organic, biological fluids composition, as well solid samples, on a ferrofluid-infused porous surface. We specifically...
An activity-directed fractionation and purification process was used to isolate antioxidant components from cassava stems produced in Hainan. The ethyl acetate n-butanol fractions showed greater DPPH˙and ABTS·+ scavenging activities than other fractions. fraction subjected column chromatography, yield ten phenolic compounds: Coniferaldehyde (1), isovanillin (2), 6-deoxyjacareubin (3), scopoletin (4), syringaldehyde (5), pinoresinol (6), p-coumaric acid (7), ficusol (8), balanophonin (9)...
Crack-free amorphous photonic crystals, showing high color visibility and low angle dependence, have been fabricated by simple co-assembly.
Polymeric coatings that show tunable mechanical strength, healing ability of damage, and proper liquid repellency will be promising in various areas across life industry. However, the exploitation such coating materials is largely limited by their molecular design. In this work, polymeric with ion-controlled mechanics coloration damage-healing oil-sliding properties have been demonstrated based on a supramolecular design dual-cross-linked polysiloxanes. The color can adjusted coordinative...
Precise and robust manipulation of air bubbles will favor intense demands from governing processes chemical reactions to enhancing transportation efficiency in multiphase engineering systems. Inspired by the working mechanism mucous lining lung alveoli, elastic liquid-infused material (eLIM) is constructed infiltrating an interconnected porous elastomer with a low-surface-energy liquid. With help liquid, pore pressure channels eLIM can be reversibly regulated under mechanical stretching,...
Abstract Humidity‐based power generation that converts internal energy of water molecules into electricity is an emerging approach for harvesting clean from nature. Here it proposed intrinsic gradient within a humidity field near sweating surfaces, such as rivers, soil, or animal skin, promising resource when integrated with liquid‐infused nanofluidics. Specifically, capillary‐stabilized ionic liquid (IL, Omim + Cl ‐ ) film exposed to the above create sustained transmembrane water‐content...
A nanocomposite carbon was prepared by grafting a carbonizable polymer, poly(furfuryl alcohol) (PFA), to single-wall nanotube (SWNT). The SWNT first functionalized with arylsulfonic acid groups on the sidewall via method using diazonium reagent. Both Raman and FTIR spectroscopies were used identify functional surface. HRTEM imaging shows that bundles are exfoliated after functionalization. Once this state of SWNTs accomplished, PFA-functionalized (PFA-SWNT) in situ polymerization furfuryl...

Abstract Surface‐deposited pathogens are sources for the spread of infectious diseases. Protecting public facilities with a replaceable or recyclable antifouling coating is promising approach to control pathogen transmission. However, most coatings less effective in preventing pathogen‐contained respiratory droplets because these tiny difficult repel, and deposited can remain viable from hours days. Inspired by mucus, an antimicrobial supramolecular organogel microdroplet‐mediated developed....
