Abstract
A method of preparing a fluorinated polycaprolactone membrane includes 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.
