Droplet-based millifluidic device under microwave irradiation: Temperature measurement and polymer particle synthesis.

Résumé

The microwave irradn. and the droplet-based millifluidic process are coupled to explore the microwave heating of individual droplets in polymer chem. The continuous phase is a microwave-inert oil while the reactive droplets contain hydrosol. monomer and initiator in an aq. medium. Microwaves affect directly and preferentially the mols. within the reactive droplets. Addressing the challenge of a suitable millifluidic system coupled to microwave irradn., the device was design to answer geometrical and chem. specifications. To get around the issue of the measurement and the control of the droplet temp. while flowing inside the microwave cavity, the use of a chem. probe was developed (azoic compd.) with an assessment in the range of 50-90 °C. The polymn. in the droplet-based millifluidic device and microwave irradn. was successfully performed on acrylic acid under 90 W at a temp. within 60-70 °C. [on SciFinder(R)]
