Despite the extensive literature on organosilane hybrid materials, there are very few reports on the preparation of purely organosilane non-woven fibrous mats. Nevertheless, their use in various application fields may be of great importance regarding the global issue of polymer fibers and the toxicity of other compounds used so far in the composite polymer-organosilane fiber-manufacturing process. The greatest obstacle seems to be the supposed difficulty in the polymerization of organosilanes in a spinnable polymeric solution. In this work, we report the one-pot synthesis of electrospun organosilane fibers without any kinds of surfactants, low-molecular-weight polymeric gelators or spinnable polymers. The purely organosilane fibrous mats were prepared only via a suitable adjustment of the sol-gel processing parameters and were successfully produced an industrial electrospinning device, promising possible fabrication on a large scale. Moreover, the use of two differently-structured model benzene functionalized organoalkoxysilanes proves the possibility of designing a molecularly engineered material tailored to specific applications. These organosilane fibrous mats seem to be promising in various application fields, such as reusable catalysts, adsorption or conducting membranes or as novel biomaterials. This latter of these areas was preliminarily studied herein.
