solution of any water soluble thermoresponsive polymer or a solution of any organo soluble thermoresponsive polymer in a suitable organic solvent any appropriate method known to those having ordinary skill in the art can be used for preparing the polymer solution for example combining a polymer and a solvent at a temperature below lcst followed by energetic stirring an example of a polymer solution that can be used includes an aqueous solution i e the solvent is water of a water soluble thermoresponsive polymer the aqueous polymer solution can contain between about 0 005 mass and about 50 mass of the water soluble thermoresponsive polymer for example between about 0 2 mass and about 0 5 mass of the water soluble thermoresponsive polymer the balance comprising de ionized water another example of the polymer solution that can be used includes an organic solvent solution of an organo soluble thermoresponsive polymer the organic solvent polymer solution can contain between about 0 005 mass and about 50 mass of the organo soluble thermoresponsive polymer for example between about 0 2 mass and about 0 5 mass of the organo soluble thermoresponsive polymer the balance comprising a suitable organic solvent the thermoresponsive polymers that can be used to prepare the polymer solution can be capable to form a solution having the lcst within a range between the melting point of the solvent and the boiling point of the solvent for example the lcst of either an aqueous polymer solution or.
