The major bonding environment remains unchanged for both standard and nanofibrous poly aniline structures. The presence of two bands in the vicinity of 1,500 cm and 1,600 cm is assigned to the nonsymmetric C6 ring stretching modes. The higher frequency vibration at 1,600 cm is for the quinoid rings, while...

Chitosan, sodium chondroitin sulfate, and pectin-nanofibrous mats were prepared from the respective polysaccharide/poly(ethylene oxide) blend solutions by electrospray. Unblended polysaccharide solutions showed low processability, i.e., the solutions could not be electrosprayed. The addition of 500 kDa poly(ethylene oxide) to chitosan solutions enhanced the formation of a fibrous stmcture. Sodium chondroitin sulfate/poly(ethylene oxide) and pectin/poly(ethylene oxide) blend solutions were generally too viscous to be sprayed at 25 °C, but at 70 °C the fibrous stmcture was formed [61].

Poly(ethylene glycol) (PEG), also known as poly(ethylene oxide) (PEO), is a hydrophilic, biocompatible polyether. PEG usually refers to a material with relatively low molecular weight (e.g., several thousands), while PEO to a material with high molecular weight (e.g., over tens or hundreds of thousands). PEO is wafer soluble and therefore can be electrospun into nanofibres from its water solution (Deitzel et al., 2001). However, water solubility makes the material unstable in a biological environment. Consequently, PEO or PEG is usually used in combination with other natural (e.g., collagen, chitosan) or synthetic polymers (e.g., PLA) in blends or copolymers (Subramanian et al., 2005 Szentivanyi et al., 2009).
