Nano and submicrometric fibers of TiO 2 and ZnO were produced for the first time by solution blow spinning (SBS). High surface area, homogenous, crack free TiO 2 and ZnO fibers were successfully spun, as confirmed by BET surface area, X ray diffraction (XRD), transmission electron (TEM) and scanning electron (SEM) microscopy studies. TiO 2 and ZnO fibers presented mean diameters ranging from 300 nm to 600 nm and from 200 nm to 550 nm, respectively. SBS proved to be an efficient method of producing metal-oxide semiconductor nano and submicrometric fibers at high output rates when compared other fiber spinning techniques. [ABSTRACT FROM AUTHOR]

Electrospinning is not only a technique to fabricate macroscopic fiber but also a method to control the microstructure. In this study, high-temperature solution electrospinning was used to prepare isotactic polypropylene (iPP) fibers. Scanning electron microscope (SEM) observation indicates that a single electrospun iPP fiber consists of many nano-fibrils. Based on SEM observation, these nano-fibrils are shish-kebab structure. Electrostatic elongational force involved in the electrospinning process is considered to be responsible for the development of shish-kebab structure. [ABSTRACT FROM AUTHOR]
