This study introduces a novel strategy to overcome the limitations of electrospun Polyhydroxybutyrate (PHB) nanofiber mats, particularly their suboptimal mechanical properties. Plasma-powder functionalisation using Diffuse Coplanar Surface Barrier Discharge (DCSBD) for different treatment times (up to 8 min) and subsequently reinforcing it with Halloysite Nanotubes (HNTs) developed an electrospun nanofiber mat with enhanced structural and mechanical properties, demonstrating a potential candidate for advanced applications. Although reinforcing the PHB electrospun nanofibers with HNTs increased the average diameter to 1.89 μm, 2-min plasma functionalisation of PHB powder (2min-pPHB-HNTs) developed a significantly thinner nanofiber mat, resulting in a 48 % decline in the average nanofiber diameter. Scanning Transmission Electron Microscopy (STEM) analysis revealed a well-dispersed HNTs network within the PHB matrix, resulting in a fibrous structure with enhanced tensile strength (4.59 MPa). In comparison, 2min-pPHB-HNTs represented 6.17 MPa in tensile strength. Toughness of the HNTs-reinforced, 2-min plasma-treated mat is 1.23 MJ/m3 compared to 0.65 MJ/m3 for HNTs-reinforced, untreated PHB mat. Also, the samples were characterised with other analytical methods, e.g., SEM, porosity, ATR-FTIR, WCA/SFE, and XRD, to evaluate the efficiency of plasma-powder functionalisation and HNTs reinforcement on the structural and chemical properties of the electrospun PHB-HNTs nanofiber mat.
