Fullerene C60 and its Derivatives as Nanocomposites in Polymer Nanofibres

摘要

This work describes the application of oxo-derivatives of fullerene C60 and pristine fullerene as a nanocomposite in polymerous nanofibres. In this work we used oxo- fullerene derivative, of which preparation was presented by the authors of the State office for nuclear safety (Prague) on Nanocon 2009 and on Nanocon 2010 [1, 2]; there was presented its application in vivo as a radioprotective agens. With respect to wild spectrum of potential utilization of unique chemical, structural a electron properties of fullerene we investigate its another possible technical application as nanocomposite in polymer nanofibres. The nanocomposite polymer nanofibers were produced by needle-less electrospinning method. Polyvinyl alcohol, polyurethane a polyvinyl butharate were used as polymers. Thermal resistance of obtained nanofibres without and with nanocomposites was tested by simultaneous thermogravimetric analysis and differential thermal analysis (TGA/DTA). The retarding influence of fullerene and its derivative on the course of the thermal decomposition of nanofibres is discussed.
