Abstract

Poor mechanical strength of nanofibrous structures is a crucial challenge in implementing them in many fields such as filtration, protective clothing, wound dressing, and tissue scaffolds. Hence, researchers are still working on different methods of imparting strength into both nanofibrous structures and individual nanofibers to improve their performance. In this chapter, these methods are categorized and discussed in four general categories: application of nanoparticles and fillers in the fiber structure, improving the molecular orientation and also fiber alignment in the nanofibrous structure, twist insertion, and imparting strength by initiating interfiber bonding. In addition, the different methods of inserting adhesion bonding between nanofibers and also different theories of adhesion are addressed here.
