Titanium fiber mats

Applying a similar method to the nylon fibers with a more concentrated precursor resulted in films containing a hollow morphology on removal of the fibers. Hence in this case a casting of the fibrous mat was attained. It was noted that the film containing the fiber had relatively few cracks compared with the flakes formed after calcination by the deposition of the titanium precursor on a glass slide without the fibers [43]. 

Lev et al. have studied chemical methods to counteract nerve agents and remediate organophosphate (OP) contamination by means of nanoparticles, polymers, and nanofibers functionalized by a-nucleophilic agents [38, 39], Fibrous mats functionalized with a-nucleophilic oxime moieties were prepared by either electrospinning blends of polyacrylamidoxime and PAN or surface oximation of prefabricated PAN fibrous mats and demonstrated to possess a pronounced capability to hydrolyze chemical nerve agent simulants in the presence of moisture [39]. The layer-by-layer electrostatic assembly technique offers another strategy for electrospun fiber surface functionalization [40]. For the application in protective fabrics, Lee et al. demonstrated that electrospun fibers used as the substrate for titanium dioxide nanoparticle coatings resulted in increased specific substrate surface areas of about 10 that of the flat film, which enhanced photocatalytic decomposition of toxic industrial chemicals (Fig. 14.4a-c) [41,42].
