A method and apparatus for inserting a medical device such as a cannula tip within a peripheral vein of a human body wherein the medical device includes a micro- or nano-structured superhydrophilic basecoat and a liquid topcoat, together comprising a superhydrophobic coating, which inhibit occlusion and/or catheter related bloodstream infection.
摘要:
This disclosure relates to halogen-free flame retardant polycarbonate/thermoplastic polyester molding compositions with improved mechanical properties and increased polyester loading level. More particularly, the disclosure relates to halogen-free polycarbonate/ thermoplastic polyester resin alloys with polymeric phosphorus flame retardant additive and siloxane impact modifier. Also included are methods for preparing such compositions and articles there from.
摘要:
The present disclosure relates to bearing and seal assemblies comprising a composite structure which includes a substrate and a layer disposed on the substrate. The layer disposed on the substrate includes a polyimide matrix and a filler dispersed within the polyimide matrix. The filler can be a thermoplastic polymer, such as PTFE, and/or an organic filler. The bearing assembly can exhibit a synergistic improvement in wear resistance and coefficient of friction.
