Dye releasing control from rice husk silica nanoparticle (NP/SiO2) immobilized in polycaprolactone (PCL) nanofiber sheet was conducted depending on the diverse nanoporosity of NP/SiO2 by decomposing of PCL. The nanoporous silica was extracted from rice husk as known biomass and synthesized with controlling of the factors such as pH, amount of used rice husk ash and aging time, drawing the specific surface area and pore size 155.25 ~ 632.08 m2/g. PCL nanofiber sheet was fabricated from the electrospinning method, including NP/SiO2 dispersed in the surface of its thread by acoustic mixer. The samples were sampling the releasing of dye by decomposing PCL in PBS under 38℃ at 100rpm inside incubator, then compute the degree of the amount of the dye release by UV-spectroscopy. |
