Herein we report a versatile method for the preparation of triboluminescent polymer films by physical blending with common luminophores. This method does not require the presence of a crystalline phase or the use of materials known to be triboluminescent. Emission is generated in response to friction of the polymer surface via triboelectrification, either by rubbing directly or through an inert coating layer, even with low applied stress (<0.1 MPa). Our findings offer a convenient and practical method of preparation of triboluminescent, amorphous polymer films with easily tunable emission properties.

在与普通发光体混合的聚合物薄膜中产生摩擦发光的通用方法

在这里，我们报告了一种通过与普通发光体物理共混来制备摩擦发光聚合物薄膜的通用方法。该方法不需要存在结晶相或使用已知摩擦发光的材料。即使在施加低应力（<0.1 MPa）的情况下，也会通过摩擦起电，通过直接摩擦或通过惰性涂层摩擦聚合物表面的摩擦而产生发射。我们的研究结果提供了一种方便实用的制备摩擦发光、无定形聚合物薄膜的方法，该薄膜具有易于调节的发射特性。
