Abstract
An ostomy pouch has a pair of opposed side walls, one of the side walls defines a stoma-receiving opening for, in use, receiving a part of a stoma into the ostomy pouch, one or both of the side walls being formed of a polymeric film at least partially coated on an internal surface thereof with hydrophobic particles, the hydrophobic particles includes: a metal oxide core; and a hydrocarbon chain having from 2 to 40 carbon atoms, wherein the hydrocarbon chain is chemically bound to the metal oxide core.

An ostomy pouch having a pair of opposed side walls, one of the side walls defining a stoma-receiving opening for, in use, receiving a part of a stoma, one or both of the side walls being formed of a polymeric film at least partially coated on an internal surface thereof with adhered hydrophobic particles, the hydrophobic particles comprising:
- an iron oxide core;
- and
- a hydrocarbon chain having from 2 to 40 carbon atoms,
- wherein each of the hydrophobic particles is spherical,
- wherein the hydrophobicity of the polymeric film is tuned at different regions across the internal surface such that a first region of the polymeric film has an associated first water contact angle measurement and a second region of the polymeric film has an associated second water contact angle measurement which differs from the first water contact angle measurement, wherein the first and second regions of the polymeric film are each coated with the hydrophobic particles, and
- wherein the hydrocarbon chain is covalently bound to the iron oxide core via a functional group, the functional group comprises any one or a combination of carboxylate, phosphinate, thiolate and/or thiocarboxylate.
