摘要

In the present research work, PCL electrospun membranes were prepared and characterized with AgNPs obtained from Dividivi extract. The extracts were obtained by centrifugation and boiling. These extracts were used to synthesize AgNPs, using extract: AgNO3 ratios (1:2 and 1:3) with three temperatures (80, 90, and 100 °C). The AgNPs were evaluated by UV Visible, showing an absorption signal at 420 nm. The membranes were obtained by electrospinning following certain conditions. FTIR, SEM, EDS, and contact angle characterized the membranes. FTIR revealed a C=O group corresponding to the formation of AgNPs. SEM analysis identified 1–4 µm fibers distributed throughout the membrane with branching. Morphological changes were observed on the fiber surface, covered by a layer possibly due to AgNPs. The contact angle demonstrated the hydrophobic effect of the membranes.
