A stretchable wiring film includes: (A) a stretchable film made of, at least as a top surface of the stretchable film, a cured product of a stretchable film material containing a silicone polyurethane resin; and (B) a stretchable wiring. The top surface of the stretchable film has a repeated uneven pattern formed with depths of 0.1 µm to 5 mm and pitches of 0.1 µm to 10 mm. The stretchable wiring is formed on the top surface of the stretchable film where the repeated uneven pattern is formed. Thus, the present invention provides: a stretchable wiring film having less decrease in electric conductivity in stretching and excellent water repellency on the film top surface; and a method for forming the stretchable wiring film.
一种可拉伸配线薄膜包括(A) 可拉伸薄膜,至少作为可拉伸薄膜的顶面,由含有
硅酮聚
氨酯
树脂的可拉伸薄膜材料的固化产品制成;以及 (B) 可拉伸布线。可拉伸薄膜的顶面具有重复形成的不均匀图案,其深度为 0.1 微米至 5 毫米,间距为 0.1 微米至 10 毫米。可拉伸布线形成于形成重复不均匀图案的可拉伸薄膜顶面上。因此,本发明提供了:一种在拉伸过程中电导率下降较少且薄膜顶面具有优异防
水性的可拉伸布线薄膜;以及一种形成该可拉伸布线薄膜的方法。
