The aim of the work was to compare the degradation behavior of electrospun nanofibres obtained from pure poly(lactic acid) (PLA) and modified with carbon nanotubes (CNTs) in aqueous environment.
The nanofibres in the form of mats were manufactured using the electrospinning technique (ES) with potential biomedical application.
To investigate the degradation behavior, one-component and composite (containing CNTs) nanofibres were compared using scanning electron microscopy (SEM), water contact angle measurements, differential scanning calorimetry (DSC), and mechanical testing.
The changes in their morphology, structure, and selected physical and mechanical properties during incubation up to 14 days were analysed.
Two types of CNTs differing in concentration of surface functional groups were used to modify the PLA nanofibres.
PLA and composite nanofibres (PLA + CNT) during incubation underwent swelling and partial degradation due to the penetration of water into polymer matrix.
Changes in the mechanical properties of composite mats were higher than those observed for pure PLA mats.
After 14-day incubation, samples retained from 47 to 78% of their initial tensile strength, higher for PLA samples.
Morphological changes in pure PLA nanofibres were more dynamic than in composite nanofibres.
No significant changes in crystallinity, wettability, and porosity of the samples occurred.
