Kohlenstoffaserverstärktes Polysulfon - ein neuer Implantatwerkstoff - Carbonfibre Reinforced Polysulfone - A New Biomaterial

Abstract

Carbon fibre reinforced polysulfone is a composite material which contains two materials of well known biocompatibility. In comparison to metals this composite material has some advantages which makes it favourable particularly for implants in tumor surgery. The custom made arrangement of fibres in the composite allows the development of implants with special mechanical properties. The radiolucency of the material avoids problems caused by the reflection of x-rays, using metal implants. This special property allows the exact calculation of postoperative radiation doses of tumor patients. Simultaneously the structures behind the implants are not hidden. All implants can be machined during the operation to adapt them to the individual anatomical situation. Animal experimental and clinical applications of plates, screws and spinal segmental replacement implants made of this composite material have shown good results so far.

Ionic transport processes in polymer mixture solutions based on quaternized polysulfones

“…Polysulfones, produced through polycondensation, are known as high-performance materials with superior thermal, chemical, and mechanical properties, which represents an advantage for many applications, such as filtration membranes [28][29][30][31][32], coatings [33,34], composites [35][36][37], microelectronic devices [38], thin film technology [39], biomaterials [25,37,40], and fuel cells [41][42][43][44]. Introduction of functional groups into polysulfones solves some limitations, and also extends the range of potential applications of these high-performance materials through the specific properties gained, and thus provides wider scope.…”
