Abstract
Electrospinning is a simple, low cost, and high throughput technique that allows for processing of polymers into fibers. The process can be controlled to allow access for well-defined continuous fibers that are of interest for a wide range of applications including as tissue scaffolds, as nanowires in optoelectronic devices, and in catalysis. Conventional electrospinning processes use polymer solutions with high molecular weights. Here, we report the electrospinning of one-dimensional (1D) fiber-like block copolymer micelles containing a crystalline core. We successfully accessed core-shell microfibers in which 1D micelles containing a crystalline poly(ferrocenyldimethylsilane) (PFS) core are immobilized on a polystyrene microfiber via coaxial electrospinning. Furthermore, we describe efforts to extend this approach to the use of 1D micelles comprising of a crystalline, π-conjugated poly(di-n-hexylfluorene) (PDHF) core. Electrospinning was also successfully used to prepare microfibers consisting solely of 1D micelles with a PFS crystalline core, the first examples where a template material is not required.
