This work investigates the effects of adding MgO and Mg(OH)2 nanoparticles on the morphology, thermal properties, and mechanical properties of poly(e-caprolactone) (PCL)-based electrospun fiber mats. The study finds that adding nanoparticles increases the fiber diameter and reduces the onset degradation temperature and maximum degradation temperature. Furthermore, the addition of nanoparticles decreases the crystallinity of the reinforced fibers.
In this work, a comparative study between the morphology, the thermal and the mechanical properties of poly(e-caprolactone) (PCL)-based electrospun fiber mats reinforced with both MgO and Mg(OH)(2) nanoparticles, is carried out. Both MgO and Mg(OH)(2) nanoparticles have been added in a range of concentrations such as 0.5, 1, 5, 10, 20 wt% with respect to the PCL matrix, with the aim of improving their mechanical properties in comparison with neat PCL electrospun fibers. From the morphological point of view, electrospun fibers are randomly collected and an increase in the average fiber diameter with the addition of nanoparticles is observed. The addition of both types of nanoparticles lower the onset degradation temperature as well as the maximum degradation temperature of neat ePCL of about 50 degrees C with the higher content of nanoparticles. Furthermore, PCL electrospun nanofiber mats show a degree of crystallinity of 53%, which is quite high. However, the addition of 20 wt% of both MgO and Mg(OH)(2) lowers the crystallinity of the reinforced electrospun fibers to 50% and 43% for PCL + MgO 20 wt% and Mg(OH)(2) 20 wt%, respectively.
