近年来,人们十分希望能有一种可以不受污染及涂鸦弄脏的不粘建筑物。为此,德国研制了一种可杜绝涂鸦的不粘涂层,可令任何建筑物,包括地铁站的墙壁或地面,都能象不粘锅那样抗拒尘垢及污染。 目前,为使长柄锅成为不粘锅,内部都涂上了一层聚四氟乙烯。但是,这种聚四氟乙烯不是一种理想的不粘物质,因为它很难加工,而且除了平滑的表面外,很难应用到其它物料的表面上去。 In recent years, people very much hope that there will be a non-stick building that can be stained by pollution and graffiti. To this end, Germany has developed a non-stick coating that can eliminate graffiti, so that any building, including the wall or ground of a subway station, can resist dust and pollution like a non-stick pan. At present, in order to make the saucepan non-stick pan, the interior is coated with a layer of Teflon. However, this PTFE is not an ideal non-stick material because it is difficult to process and it is difficult to apply to the surface of other materials except for smooth surfaces.
