The relations between wear behavior and basic material properties of graphene?based materials reinforced ultrahigh molecular weight polyethylene

Biomechanical Properties of Dispersep Article Reinforced Polymer Composites on Ultrahigh Molecular Weight Polyethylene (UHMWPE)

Ultrahigh molecular weight polyethylene (UHMWPE) having a low coefficient of friction (CoF), high wearand chemical resistance in harsh environments, is used for fabricating medical products (hip and knee joints, intervertebral discs, plates for maxillofacial surgery, and others). Priority of polymers, in particular UHMWPE to be applied as medical implant materials, is due to their proximity to ...

Wear of Ultra High Molecular Weight Polyethylene

Ultra-High Molecular Weight Polyethylene: Influence of the Chemical, Physical and Mechanical Properties on the Wear Behavior. A Review

Ultra-high molecular weight polyethylene (UHMWPE) is the most common bearing material in total joint arthroplasty due to its unique combination of superior mechanical properties and wear resistance over other polymers. A great deal of research in recent decades has focused on further improving its performances, in order to provide durable implants in young and active patients. From "historical"...

A comparison of the wear and physical properties of silane cross-linked polyethylene and ultra-high molecular weight polyethylene.

Cross-linked polyethylenes are being introduced widely in acetabular cups in hip prostheses as a strategy to reduce the incidence of wear debris-induced osteolysis. It will be many years before substantial clinical data can be collected on the wear of these new materials. Silane cross-linked polyethylene (XLPE) was introduced into clinical practice in a limited series of acetabular cups in 1986...

Surfactant Effects on Structure and Mechanical Properties of Ultrahigh-Molecular-Weight Polyethylene/Layered Silicate Composites.

In this study, the reinforcement of ultrahigh-molecular-weight polyethylene (UHMWPE) with biotite was investigated. The biotite filler was mechanically activated with different dry surfactants to improve its compatibility with UHMWPE and decrease agglomeration among biotite particles. Alkyldimethylbenzylammonium chloride (ADBAC) and cetyltrimethylammonium bromide (CTAB) were selected as cationi...
