abstract = "Activated carbon fibers (ACFs) are known as excellent adsorbent
materials due to their fast adsorption rate and easy handling
characteristic. The ACFs can be manufactured from the
poliacrilonitrile fiber, based on a usual carbon fibers (CFs)
production process accomplished by an additional activation
process. On the other hand, activated carbon fiber may be
manufactured by poliacrilonitrile from textile use. The aim of the
present work is to describe the production, characterization
results, and application studies of activated carbon fiber felt
(ACFF) produced from textile PAN fiber, using a set of homemade
equipment. The 5.0 dtex PAN fiber tow with 200 thousand filaments
was oxidized and used as raw material for felt production. The
oxidized PAN fiber felt (OPFF) was displaced in a special sample
holder, carbonized (900 °C) and then activated in CO2 atmosphere
at 1000 °C in an electric tubular furnace. All steps of the
process were performed as fast as possible, and characterization
was done by 77 K N2 isotherms, adsorption isotherms in liquid
fases, SEM, DRX, RAMAN surface chemistry. The results confirmed
the production of essentially microporous (pore < 3.2 nm, centered
on 1.2 nm), 1.300 m2/g activated carbon fiber felt. After that was
performed electrochemical characterization for studies application
as a supercapacitor electrode.",
