An easily assembled double T-shape microfluidic devices for the preparation of submillimeter-sized polyacronitrile (PAN) microbubbles and polystyrene (PS) double emulsions

摘要

A simple way to prepare water-in-oil-in-water (W-1/O/W-2) and oil-in-water-in-oil (O-1/W/O-2) double emulsions which is based on commercial double T-junction tubes was set up, which shows the remarkable advantages of simplicity, operatability and cost-efficiency comparing with the traditional poly( dimethylsiloxane) (PDMS) microchip. By this device, the stable polyacrylonitrile (PAN) microbubbles have also been produced based during the experiments. The success in producing PAN microbubbles provides a new possibility for the preparation of hollow microspheres with polymer materials, which have the further potential applications in numerous particular fields.
