cze FUNCTIONALIZATION OF INDUSTRIALLY PRODUCED POLYMERIC NANOFIBROUS MATERIALS AT PARDAM, LTD. Industrial production of polymeric nanofibers leads to new applications of well-known and broadly used polymeric materials. Added value is created by formation of these materials into fibrous nanostructures. Subsequent added value is achieved by functionalization. Generally, functionalization can be achieved by adding functional components into the spinning solution or by post-treatment of the spun nanofibrous material. Company Pardam primarily focusing on industrial nanofiber production has successfully tested processes of functionalization of its nanofibrous products. As an example of adding functional components into the spinning solution the incorporation of Ag nanoparticles with antibacterial effect into the polymeric nanofibrous membranes for water filtration is presented. Antibacterial effect was experimentally confirmed in cooperation with company NanoTrade that prepared suitable Ag nanoparticles solution. As an example of functionalization by post-treatment the increasing of nanofibrous membrane conductivity by impregnation with a conductive polymer (PEDOT:PSS) dispersion is presented. The electric resistance was decreased by at least three orders of magnitude to values of hundreds of ?. There is a wide range of ways to functionalize nanofibrous materials and these examples are not meant to be an exhaustive list of successful modifications that Pardam can achieve.
