Textured and Hierarchically Constructed Polymer Micro- and Nanoparticles

Microfluidic techniques allow for the tailored construction of specific microparticles, which are becoming increasingly interesting and relevant. Here, using a microfluidic hole-plate-device thermal-initiated free radical polymerization, submicrometer polymer particles with highly textured surface were synthesized. Two types monomers applied: (1) methylmethacrylate (MMA) combined crosslinkers (2) divinylbenzene (DVB). Surface texture morphology can be influenced by series parameters such as monomer–crosslinker–solvent composition, surfactants, additives. Generally, most structured surfaces simultaneously uniform obtained in DVB–toluene–nonionic-tensides system. In second approach, poly-MMA (PMMA) used to build aggregates bigger particles. For this purpose, tripropyleneglycolediacrylate (TPGDA) synthesized co-flow arrangement polymerized light- irradiation. Then, PMMA assembled at their surface. third step, these composites dispersed an aqueous acrylamide–methylenebisacrylamide solution, again was run through co-flow-device photopolymerized. As such, entities consisting three different size ranges—typically 0.7/30/600 µm—were obtained. The both approaches potentially suitable loading or incorporation analytic probes catalysts dyes metals.
