Nanostructured materials based on aromatic heterocyclic polymers, polyheteroarylenes (PHA) are now widely common in photovoltaics, membrane technologies, sensor and electrochemical devices, etc. New PHAs convertible by electrospinning to nanofiber mats are demanded on modern state of nanotechnology for example as high performance carbonaceous material of gas diffusion electrodes (GDE) for hydrogen-air polymer electrolyte membrane fuel cell (PEMFC). The spinnability of polyheteroarylenes was not a subject of large investigations. The process of PHA electrospinning is a very challenging task. There are no general methods which would allow obtaining an electrospun material certainly. Failing to find a right set of electrospinning conditions may lead to the impossibility of nanofiber formation. Hence, many parameters of the electrospinning process should be found empirically, which in some cases is a long and routine process. Only few papers describe nanofiber materials based on some polyimides, m-polybenzimidazole (m-PBI) and semi-ladder PIM-1 obtained only on so called â�?�?needleâ�? setups. Elmarcoâ�?�?s first â�?�?needle-freeâ�? electrospinning equipment Nanospiderâ�?¢ is proved by industrial operation; a technology based on spinning from a free liquid surface. Needle-free process guarantees optimal distance between Taylor cones, excellent web and fiber uniformity, simplicity of design, robustness against clogging of a spinneret, increased productivity due to the simultaneous operation of numerous jets. The lecture will be devoted to the production of new high-tech PHAs nanofibers and non-woven materials eminently suitable for electrochemical applications. Recent Publications: 1.
