For preparation, blending the PC resin, ABS resin, PEO resin, antioxidant and lubricant in a mixer; and putting a mixture in a twin-screw extruder for granulation, thus producing easily-plated PC/ABS alloy. The method is simple and practicable. PEO resin makes PC/ABS surface have the property of hydrophilicity, which makes the etching solution easier to wet the surface when under etching, so that the etching becomes much easier. The binding force of hydrophilic group on the surface of PEO to the metal is strong. The binding force of PC/ABS alloy material is improved due to the combination between the chemical bond and physical force.

  • Patent number: 9327058
    Abstract: The present disclosure generally provides a stent-graft for insertion into a body vessel that comprises hydrophilic polyurethane hydrogel cuffs and an elongated cylindrical body. This stent-graft exhibits an enhanced ability to maintain its original position when placed into a patient and resist the potential of migration without causing excessive discomfort to the patient. Upon exposure to bodily fluids, the cuffs of the stent-graft expand to exert a sealing or anchoring force against the wall of the body vessel. Such a stent-graft overcomes many of the problems associated with conventional stent-grafts as currently used in many different applications, for example, endovascular repair and ureteral drainage.
