Thermo‐Responsive Microcapsules: Thermo‐Responsive Microcapsules with Tunable Molecular Permeability for Controlled Encapsulation and Release (Adv. Funct. Mater. 24/2021)

Synthesis of tunable thickness-to-diameter ratio microcapsules via a diffusion-controlled process for temperature-responsive release

“…8 In previous research, researchers mainly focused on designing microcapsules with functionalized shell materials for trig-gered release, which usually required a complicated synthesis process. [9][10][11] A well-designed shell with a tunable cut-off threshold of permeation was used to prepare thermo-responsive microcapsules; 11 however, the complex water-in-oil-inwater double emulsion droplet system and the solvent conditions required for swelling limited the application areas. In contrast, a route for triggered release through mechanical cracking as well as physical change in the shell material, such as pressure-induced failure or shell melting, seems simpler as well as more universal.…”
