Abstract

Polyacrylonitrile (PAN) films were reacted with four amine compounds (hydrazine, ethylenediamine (EDA), diethylenetriamine (DETA), and triethylenetetramine (TETA)) in various concentrations of aqueous N,N'-dimethylformamide (DMF) to produce highly hydrophilic films that maintain their shape during and after modification. Add-on's (increases in weight) and amine contents (moles of amine groups per g sample) of the amino-modified PAN films were compared. Add-on's increased in an order of hydrazine, TETA, DETA, EDA when PAN reacted with equimolar concentration of the four amines, while the amine content increased in an order of TETA, DETA, hydrazine, and EDA. Although EDA produced a film with high add-on and amine content, it made the modified film highly swollen and soluble in the reaction medium. Among the four amines, hydrazine resulted in the highest amine content and moisture regain. Moisture regain as high as 23.0% was obtained when 1.2 M hydrazine was used. The moisture regains of the modified PAN films increased linearly depending on the amine content.
