The Effect of Solvent and Pressure on Polycaprolactone Solutions for Particle and Fibre Formation

Polycaprolactone (PCL) is a widely used material in many applications to tackle health problems worldwide. Formed micro- or nanosized PCL particles and fibres benefit from higher surface area volume ratio are valuable those applications, thus there always push achieve smaller diameters. Electrohydrodynamic (EHD) technologies have been at the forefront production of polymeric biomaterials, pressurised gyration (PG) has also enhanced possibilities by its ability spin comparable rapid speeds. In this work, microparticles were separately produced changing key operating parameters EHD PG systems solution properties. Initially, formed electrospraying with different binary solvent systems, followed fibre various singular solvents pre-optimised system. As anticipated, use altered particle morphologies diameters, while increased pressure greatly affected characteristics resulting fibres. The morphology was found be highly dependent on technology used.
