In this study, it was aimed to produce and characterize PCL-based composite nanofibrous material containing various concentrations of sepiolite (SEP). The PCL polymer concentration kept constant at 10 wt% in consideration. Sepiolite added the solution 0, 0.5, 1.0, 1.5, 2.0, 2.5 wt % respectively. Firstly, properties prepared solutions such as viscosity, surface tension conductivity were determined. results indicated that addition SEP resulted an increase conductivity, values solutions. Then, nanofiber production carried out via electrospinning method. Subsequently, nanofibers characterized morphologically by SEMEDS analysis. analysis demonstrated all exhibited smooth, bead-free, uniform structures. Additionally, fiber diameter observed decrease increased. EDS revealed presence magnesium (Mg) silicon (Si) SEP. Considering excellent features sepiolit being biocompatible non-toxic along with those nanofibers, is thought produced can be used medical applications wound dressing, medicine, bone regeneration.

Machine learning (ML) models provide fast and accurate predictions of material properties at a low computational cost. Herein, the mechanical multiscale poly(3-hydroxybutyrate) (P3HB)-based nanocomposites reinforced with different concentrations multiwalled carbon nanotubes (MWCNTs), WS2 nanosheets sepiolite (SEP) nanoclay have been predicted. The were prepared via solution casting. SEM images revealed that three nanofillers homogenously randomly dispersed into matrix. A synergistic reinforcement effect was attained, resulting in an unprecedented stiffness improvement 132% upon addition 1:2:2 wt% SEP:MWCNTs:WS2. Conversely, increments strength only moderates (up to 13.4%). beneficial matrix ductility also found due presence both nanofillers.
