Abstract
Fluorinated derivative of cellulose acetate (CA) was prepared by simple homogeneous esterification reaction using pyridine as catalyst and pentadecafluorooctonyl chloride (PDFOC) as long chain aliphatic acid chloride. The process was optimized by changing the amount of pyridine and PDFOC. Obtained fluoro derivative of CA was freely soluble in common organic solvents such as acetone and THF. Fluorine content in the material was calculated by energy dispersive X-ray spectroscopy analyses and maximum 27.3 wt.% was achieved. X-ray diffraction results showed that fluorination reaction did not change the crystallinity of the CA.
