Morphology And Mechanical Properties

Antimicrobial viscose rayon/O-carboxymethyl chitosan fibers (VCMFs) were manufactured by spinning the mixture of O-carboxymethyl chitosan (O-CMCS) xanthate and cellulose xanthate via the viscose process. The structure, morphology and mechanical properties were investigated by infrared, scanning electron microscopy, transmission electron microscope and tensile test. The results show that the blend fibers of cellulose and O-CMCS were satisfactorily prepared and the two polymers were mixed homogeneously. VCMFs display striation along the fiber similar to those of viscose rayon fibers, and their mechanical properties are close to that of viscose rayon. With O-CMCS blended, VCMFs showed good moisture absorption and antibacterial activity against E.coli.

Morphology And Mechanical Properties

Tribological problems are the major obstacle that limits the long-term using of ultra high molecular weight polyethylene (UHMWPE) in artificial joints. Many efforts have been made to improve the tribological properties of UHMWPE mainly by promoting the structure, morphology and mechanical properties of UHMWPE. In this paper, inspired from the natural joint, the micro-scale texture has been introduced to improve the tribological properties of UHMWPE. The micro-imprint lithography technology has been adopted to fabricate the textured UHMWPE. The profile of textured UHMWPE shows that the quality of textured UHMWPE is good. The result of tribological tests shows that the micro-scaled surface texture can remarkably reduce friction on UHMWPE.
