Preparation and Characterization of Polycaprolactone/x%Cu-MOF Nanofibers

Nowadays, porous compounds especially polymeric nanofibers mats have been the subject of intense research in biological applications such as wound dressing, drug delivery, and tissue engineering [1-2]. MOFs are porous crystalline structures consisting of metal ions (or metal clusters) linked through organic linkers [3]. The main objective of the present work is the fabrication of fibrous composites from blending the Cu-MOF with poly(caprolactone) by electrospinning technique. The as-prepared compounds were characterisized by various techniques including FT-IR, PXRD, EDS mapping, SEM, and TEM.Polycaprolactone/x%Cu-MOF nanofibers by a two-step method including a hydrothermal and electrospinning process for the preparation of Cu-MOFs and PCL/x%Cu-MOF nanocomposites. The results of FT-IR, XRD, and EDS mapping were confirmed the incorporation of Cu-MOF into polycaprolactone matrix. TEM and SEM images showed that the fabricated compounds have nanofiberous morphology. Figure 1 depicts the SEM images of PCL and PCL/20%Cu-MOF nanocomposites. The SEM images revealed that PCL fibers have continuous and cylindrical shape (Figure 1a).Figure 1b shows that the morphology of PCL nanofibers wasn’t changed during composite preparation
