Nanofibrous composite materials integrating nano/microparticles between the fibres.

Original language description

This article deals with the continual incorporation of sorbent particles by the ultrasonic dispersion in situ into a nanofibrous matrix produced by the electrospinning process. The new technology is based on the use of the needleless electrospinning method in combination with the ultrasound-enhanced dispersion of sub-micro or micro particles, which are deposited between nanofibers onto the support material. The main advantage of use these two technologies in time is the independence of particle-incorporation of the electrospinning process. The sorbent particles are held in between the fibers and they remain uncovered by polymer. Thanks to free surface of sorbent particles are maintained all their active properties. Such materials can be simply cut with scissors without the releasing particles. Further the authors present figures from the electron microscopy of the newly-designed nanocomposite material and its morphological analysis, such as the particle distribution. The material was used as a sorbent of bis(2-chlorethyl) sulfide (mustard gas) with a sorption time greater than 240 minutes. This unique material has been developed to be used for protection against chemical warfare agents; yet, it can be employed for several other applications depending on the powder material dispersed onto the nanofibrous layer.
