物上加金属涂层的难点之一是这些涂层很快会被洗衣机中的水冲走。2.D。理解具体信息。根据第四段中的Yet the process takes place in such a short time on thesurface of the fabric that it should not affect the feel or quality of the finished material,织物加涂层的工序会在极短的时间内完成，以保证织物的手感和质量不受影响。3.D。理解具体信息。根据第五段中的A test of the cotton samples for their antibacterialproperties has shown that the new material is just as effective as silver at killing two bacteria知，加了铜制涂层之后的棉布的抗菌性和银器一样好，因此句中提到银是为了说明新材料的抗菌性能好。4.B。推断。文章由医生外套颜色的变化引出医务人员的衣物存在的问题一一不抗菌，接着介绍了有金属涂层的织物面临的问题，然后从涂层材料、加涂层的过程和新材料的抗菌性多个方面介绍了一个研究团队的新发明，故接下来可能会介绍这项新发明的应用前景。A项和C项的内容在上文已提到；本文是说明文，以感谢结尾不合适，故排除D项。【知识链接】1.medical implant(para.2:植入式医疗器械2.solution(para.4):溶液
