Abstract
The invention provides a method of making a material. The method comprises the step of coating a support with a solution comprising a hydrophilic polymer and a blowing agent. Either prior to or after the step of coating the support, the solution is interacted with in some way e.g. heated, to cause the blowing agent to generate gas bubbles within the solution, causing foaming of the hydrophilic polymer.
