A method for the preparation of hydrophilic elastomers involves the synthesis of polydimethylsiloxane with tunable hydrophilic surface properties. An elastomeric monolith with desired hydrophilic properties is produced by combining a polyethylene oxide polymeric surfactant additive with a PDMS base and curing agent during polymerization. The surfactant chain segment lengths are varied to control the hydrophobic/hydrophilic balance.

Hydrophilic surface modification of polydimethylsiloxane

A method is provided for depositing a hard wear resistant surface onto a porous or non-porous base material of a medical implant. The wear resistant surface of the medical implant device may be formed by a Laser Based Metal Deposition (LBMD) method such as Laser Engineered Net Shaping (LENS). The wear resistant surface may include a blend of multiple different biocompatible materials. Further, functionally graded layers of biocompatible materials may be used to form the wear resistant surface. Usage of a porous material for the base may promote bone ingrowth to allow the implant to fuse strongly with the bone of a host patient. The hard wear resistant surface provides device longevity, particularly when applied to bearing surfaces such as artificial joint bearing surfaces or a dental implant bearing surfaces. An antimicrobial material such as silver may be deposited in combination with a metal to form an antimicrobial surface deposit.
