摘要 |
Functionalized porous poly(aryl ether ketone) articles are prepared by reacting ketone groups in the backbone of poly(aryl ether ketone) polymer with a primary amine reagent. Preferred functional primary amines are primary aliphatic amines or substituted hydrazines containing one or more target functional groups including polar groups, such as hydroxyl groups, ~OH, amino groups, ~NH<SUB>2</SUB>, ~NHR, ~NRR', and ethylene oxide groups, ~OCH<SUB>2</SUB>CH<SUB>2</SUB>-, negatively or positively charged ionic groups, such as ~SO<SUB>3</SUB><SUP>-</SUP>, ~COO<SUP>-</SUP>, and ~NH<SUB>4</SUB><SUP>+</SUP> groups, hydrophobic groups such as siloxane or perfluorcarbone groups, and non-polar groups, such as linear or branched hydrocarbon groups. The functionalized porous poly(aryl ether ketone) article can be prepared by reacting primary amine with a pre-formed, shaped porous poly(aryl ether ketone) article or by functionalizing the surface of a non-porous precursor article that is subsequently converted into a porous article.
