Abstract
A material that can be formed into a porous prosthetic sleeve liner that provides particularly useful benefits for prosthetics. The material is breathable and sweat-absorbing, thus minimizing skin morbidity when used as a prosthetic liner. The material can include hydrophilic-lined continuous pores within a hydrophobic polymer, wherein the hydrophilic lining is crosslinked together with the hydrophobic polymer via non-degradable covalent interactions using chain crosslinkers.
Claims18
A method for producing a material comprising:
- producing interconnected pore spaces within a continuous phase of a hydrophobic polymer by employing internal phase emulsion templating, the internal phase emulsion templating selected from medium internal phase emulsion (“MIPE”) templating and/or high internal phase emulsion (“HIPE”) templating;
- producing a hydrophilic pore lining from hydrophilic chemical end groups of a second polymer lined within the interconnected pore spaces of the hydrophobic polymer, the hydrophilic chemical end groups produced from a hydrophilic monomer polymerized selectively at a surface of the hydrophobic polymer, wherein an aqueous phase containing a hydrophilic monomer is dispersed into the continuous phase of the hydrophobic polymer prior to Polymerization of the hydrophobic polymer;
- and
- crosslinking together the continuous phase of the hydrophobic polymer to the hydrophilic pore lining via covalent interaction using a chain crosslinker.
