Preparation and characterisation of novel PEEK-WC capsules by phase inversion technique

Capsules of PEEKWC are prepared using a membrane process combined with phase inversion technique. Polymeric droplets were prepared using a mono-pore film in polyethylene with pore diameter ranging from 300 to 1000 mm. The morphology, porosity and shell thickness of the made capsules are modified changing some process parameters such as the polymeric concentration or the non solvent in the coagulation bath.
