IPN compositions and methods of making the same are provided. The IPN compositions can include a water swellable, water permeable IPN or semi-IPN member with a first polymer network including a hydrophobic thermoset or thermoplastic polymer, a second polymer network including a non-ionic polymer, and a third polymer network including an ionic polymer containing sulfonic acid functional groups that are otherwise difficult to form composites with hydrophobic polymers. The IPN compositions can be used in orthopedic implants or in mechanical applications as a bearing material.
