PREPARATION AND CHARACTERIZATION OF POLYLACTIC ACID/SILICA AND POLYLACTIC ACID/CLAYS BIONANOCOMPOSITE ELECTROSPUN SYSTEMS

Introduction Electrospinning is a versatile process technology for the production of fibers ranging from nano- to micro-scale. In order to develop high performance electrospun systems, the use of nanofillers is achieving more and more interest. In this context, silica (Si) and clays (Cl) are often used as fillers due to the possibility to combine the advantages of polymeric materials, such as light weight and flexibility, and inorganic materials, such as high mechanical strength, heat stability, and chemical stability. In this work, the morphology of PLA/Si and PLA/Cl were evaluated on two different weight ratios: 99/1 and 95/5 wt/wt. Material and Methods The nanoparticles were added to a s…
