Influence of SBA-15-type ordered mesoporous silica on ibuprofen loading and releasing of electrospun polyacrylonitrile nanofibers

Electrospinning technique is well known as an efficient and simple method to fabricate fibers with very small diameters in the range of 10 to 1000 nanometers, and to produce nanofibers filled with various particles from both natural, synthetic, and blend polymers.1–3 The large surface area to volume ratio and high porosity of the electrospun webs make them good candidates for many different applications in various fields. Nowadays, this method is commonly used in many areas such as materials engineering, filtration, catalysis, Li-batteries, sensors, pharmaceutical, optical electronics, healthcare, chemistry, and biomedical. The electrospun webs could also be easily fabricated into various shapes such as membrane, tube, etc.4–6
