Polymerization-induced self-assembly (PISA) is used to prepare linear poly(glycerol monomethacrylate)-poly(2-hydroxypropyl methacrylate)-poly(benzyl methacrylate) [PGMA-PHPMA-PBzMA] triblock copolymer nano-objects in the form of a concentrated aqueous dispersion via a three-step synthesis based on reversible addition-fragmentation chain transfer (RAFT) polymerization. First, GMA is polymerized ...

Emulsion droplets stabilised by colloidal particles (Pickering emulsions) can be highly stable, so it is unsurprising that they are beginning to be exploited industrially. The individual colloidal particles have interfacial attachment energies that are vastly larger than the thermal energy, hence they are usually thought of as being irreversibly adsorbed. Here we show, for the first time, parti...

polybutadiene nanoparticles were synthesized via batch emulsion polymerization of butadiene in the presence of potassium persulfate, disproportionate rosinate potassium cation and t-dodecyl mercaptane as initiator, emulsifier and chain transfer agent, respectively. polymerization reaction was performed at different temperatures (60, 70 and 80 °c). conversion was measured at the various time int...

Pickering emulsions are known to be an efficient and greener alternative surfactant-stabilized emulsions. Particles, as key component of these systems, responsible for their higher kinetic stability, in recent years, the use natural organic stabilizers has emerged a solution promote sustainability. By conferring them stimuli-responsiveness and/or by polymerizing emulsion itself, design smart ad...

A method was developed for the preparation of microcapsules containing a reactive amine with potential applications in self-healing polymers. Amine core microcapsules were prepared by interfacial polymerization of an isocyanate and an amine stabilized by an inverse Pickering emulsion. Microcapsules were successfully isolated, dried, and redispersed in epoxy. Visualization of capsules in cured e...

Formation and stability of emulsions is one of the important topics in the field of colloids and interfacial science. Surfactants and colloidal particles are often used to stabilize emulsions. Surfactants are amphiphilic molecules; they minimize the energy required for the emulsion formation by reducing oil-water interfacial tension. Colloidal particles are not amphiphilic, but partially wettab...
