Effect of atmospheric pressure non-equilibrium plasma treatment on poly-L-lactic acid electrospinnability

In this work the effect of atmosferic pressure non equilibrium plasma on a Poly-L-lactic acid (PLLA) solution in dichloromethane DCM) before the electrospinning process is investigated. This is achieved using different non-thermal plasma processes to improve the electrospinnability of PLLA in a 100% DCM solution without the need to add the high-boiling point dimethylformamide (DMF) as second solvent to increase conductivity, thus avoiding the use of toxic solvents. The production of solvent-free electrospun mats for biomedical applications is a great chance to increase material compatibility and to realize useful scaffolds for tissue engineering.
