1. A method for preparing an implantable homogeneous membrane, the method comprising the steps of:

  • forming a composition comprising a dispersion of a hydrophobic-hydrophilic polymer within a matrix of a hydrophobic polymer;

    maintaining the composition at a temperature sufficient to maintain solubility of the hydrophobic-hydrophilic polymer and the hydrophobic polymer;

    applying the composition at the temperature to a substrate to form a film thereon; and

    drying the film to form a membrane.
