摘要: A method for manufacturing a high ductility Ti-, Ti-alloy or NiTi-foam, meaning a compression strain higher than 10%, includes: preparing a powder suspension of a Ti-, NiTi- or Ti-alloy powder, bringing the said powder suspension into a desired form by gelcasting to form a green artifact. The method also includes a calcination step wherein the green artifact is calcined, and sintering the artifact. The calcination step includes a slow heating step wherein said green artifact is heated at a rate lower or equal to 20° C./hour to a temperature between 400° C. and 600° C. and the Ti-, NiTi- or Ti-alloy powder has a particle size less than 100 μm. A high ductility Ti-, Ti-alloy or NiTi foam, with a compression higher than 10%, with a theoretical density less than 30%, pore size (cell size) between 50 to 1000 μm can be obtained with such a method.

摘要: A method of manufacturing a filled polymeric membrane includes a first step of preparing a filler suspension having a solvent for a glassy polymer and nanometre-sized particles. The nanometre-sized particles in the filler suspension are aggregated in aggregates having an average aggregate size in the range between 50 nm and smaller than 200 nm. In a following step, the glassy polymer is added to the filler suspension to obtain a polymer suspension. Next, the glassy polymer is dissolved in the polymer suspension. In a next step, the polymer suspension is cast on a substrate, followed by a step of removing the solvent. A filled polymeric membrane includes aggregates of nanometre-sized filler particles. The membrane is used in pervaporation and nanofiltration.

The dense shell shields the porous core from in-growth of soft tissue. The porous core part has open interconnected pores. A method of manufacturing a surgical implant includes the steps of: producing a porous core part, applying a viscous suspension on a part of the surface of the porous core part and applying a thermal treatment.
