“…[1][2][3][4][5] Besides different polymer films, the surface of polymeric nanofibers, produced via electrospinning, have already been modified using plasma technology. [6][7][8][9][10] Attention and interest in nanofiber technology has substantially grown in the last decades due to their unique properties and many potential biomedical applications such as tissue engineering scaffolds, wound dressings, drug delivery devices as well as many other industrial applications. [11,12] In the biomedical field, there is a great tendency to use nanofibers generated from biodegradable polymers due to their similarity to native tissues which is believed to result in improved cell interactions and extracellular matrix generation.…”

Morphology, crystallinity, thermal, and mechanical properties of nanofibrous mats are known to highly affect the behavior of these materials in desired applications. In this study, multiple characteristics of poly(lactic acid) (PLA) nanofibrous mats prepared from plasma‐treated pre‐electrospinning solutions are studied as a function of various plasma operational parameters. X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, X‐ray photoelectron spectroscopy, scanning electron microscopy, and tensile tests are performed. In addition, the pristine and plasma‐treated PLA solutions are examined with size exclusion chromatography to study the effect of the conducted pre‐electrospinning plasma treatments (PEPT) on the molecular weight of PLA. Aging analysis of the pristine and plasma‐treated solutions is also performed by evaluating the viscosity, conductivity, surface tension, and pH during an aging period of 10 days. To investigate if the results are only affected by the plasma treatment or also affected by the electrospinning, pristine and plasma‐treated PLA cast layers are also analyzed. The results reveal that PEPT preserved the surface chemical composition of the nanofibers and the molecular weight distribution of PLA, while morphology and mechanical properties of the nanofibers are considerably enhanced. Moreover, plasma‐treated polymer solutions resulted in the formation of nicely elongated nanofibers up to 4 days after plasma treatment.
