1. A method of preparing a fluorinated polycaprolactone membrane, comprising the following steps:
(1) reacting a polycaprolactone with an aminoalcohol compound to prepare a hydroxyl-terminated polycaprolactone;
(2) reacting the hydroxyl-terminated polycaprolactone with an anhydride to prepare a carboxyl-terminated polycaprolactone;
(3) reacting an ethylene glycol bromoisobutyrate with a fluorinated acrylate to prepare a hydroxyl-terminated fluoro-acrylate polymer;
(4) reacting the carboxyl-terminated polycaprolactone with the hydroxyl-terminated fluoro-acrylate polymer to prepare a fluorinated polycaprolactone;
(5) at room temperature, dissolving the fluorinated polycaprolactone in an organic solvent to prepare a solution; then naturally drying the solution at room temperature to prepare the fluorinated polycaprolactone membrane.
