Amphiphilic polymer conetworks (APCNs) have been explored for applications, including soft contact lenses, biomaterials, and membranes. They combine several important properties of hydrogels and elastomers, including elasticity, transparency, and capability to swell in water. Moreover, they also swell in organic solvents. However, their mechanical...

Microcapsules with an aqueous core can be conveniently prepared by water‐in‐oil‐in‐water double emulsion microfluidics. However, conventional shell materials are based on hydrophobic polymers or colloidal particles. Thus, these microcapsules feature a hydrophobic shell impermeable to water‐soluble compounds. Capsules with semipermeable hydrogel she...

Agricultural fungicide pollution poses a significant environmental challenge and causes adverse effects on human health. Therefore, strategies to limit fungicide usage are of paramount importance. Trichoderma fungi, due to their antagonistic activity against various pathogenic fungi, have shown potential as a sustainable alternative to chemical fun...

Agricultural fungicide pollution poses a significant environmental challenge and carries adverse consequences for human health. Therefore, strategies to limit fungicide usage have gained paramount importance. Trichoderma fungi, owing to their antagonistic activity against various pathogenic fungi, have emerged as prospective candidates for enhancin...

Microcapsules with aqueous core can be conveniently prepared by water-in-oil-in-water double emulsion microfluidics. However, conventional shell materials are either based on polymers or monomers that are soluble in the oil phase, or based on hydrophobic colloidal particles. As a result, microcapsules derived from double emulsions usually feature a...

Amphiphilic polymer conetworks (APCNs) are polymer networks composed of hydrophilic and hydrophobic chain segments. Their applications range from soft contact lenses to membranes and biomaterials. APCNs based on polydimethylsiloxane (PDMS) and poly(2‐hydroxyethyl acrylate) are flexible and elastic in the dry and swollen state. However, they are not...

Conventional processes commonly used for the fabrication of composites with high volume fraction of reinforcing elements usually require the infiltra-tion of monomers that are subsequently consolidated into a continuous pol-ymer matrix. Such infiltration step often leads to long processing times and limits the choices of materials that can be used...
