| Abstract: | Fourier Transform Infrared Spectrophotometer,Elemental Analyzer and Specific Surface Area Analyzer etc. were utilized to characterize the base PAN fiber and its partially hydrolyzed PAN-COOH fiber. The main factors that can affect the strength of the hydrolyzed fiber and how the hydrolysis reaction happened in alkaline condition were discussed. The acidic form hydrolyzed PAN-COOH fiber,of which characters (on dry basis) were: strength 9.6cN/dtex,capacity 0.26mmol/g,BET area 0.58m2/g,was prepared. And also the composition of the surface area,production rate from -CN to -COOH,the ways by which the groups of -COOH lined on the surface of the fiber and the possible maximum amount of -COOH were discussed in detail. |
