Preliminary Investigation of Possible Biochar Use as Carbon Source in Polyacrylonitrile Electrospun Fiber Production

Electrospinning with consequent thermal treatment consists in a carbon fiber production method that spins polymer solution to create fibers diameters around few hundred nanometers. The treatments are used for the cyclization and then carbonization of material at 1700 °C one hour. unique structure micro- nano-carbon makes them promising various applications ranging from future battery designs filtration. This work investigated possibility using milled gasification biochar, derived 20 kW fixed-bed gasifier fueled vine pruning pellets, as an addictive preparation electrospinning solutions. study outlined solvent cleaning wet-milling 32 µm sifting fundamental passages biochar preparation. Four different polyacrylonitrile-biochar shares were tested pure 50–50% resulting analyzed via scanning electron microscopy, energy-dispersive X-ray infrared spectroscopy. Results morphological analysis showed grains dispersed themselves well among mat all proposed shares. All solutions, once carbonized, exceeded 97%wt. content. At higher temperatures, inorganic compounds naturally showing such potassium calcium disappeared, almost carbon-pure matrix between.
