| Description | The present work studied the adhesion between two parts of composite material, a supporting textile and a polycaprolactone (PCL) electrospun nanofibers (NFs), because good adhesion between composite parts is required in some applications (i. e., wound dressings). However, spunbond polypropylene (PP) textile, often used as the electrospinning support, is hydrophobic, which can prevent NFs from adhering. The adhesion can be improved by plasma treatment of PP textile, which introduces polar functional groups and increases the hydrophilicity. Low-pressure oxygen treatment showed to be the most effective as it enhanced adhesion almost 6×, which was ascribed to the synergic effect of treatment homogeneity with the right ratio of surface functional groups and sufficient wettability. Agood agreement between tensile and loop adhesion tests was shown. |
