Mechanical nondiscoloring and antistretching photonic crystal (PC) films, especially those with stable structure colors during deformation, have great potential applications in wearable display devices, decoration, and packaging. Here, PC films with antistretching and invariant structural colors during deformation were prepared, by combining Zn²⁺ coordinated elastic material and hydroxypropyl methylcellulose (HPMC) with polystyrene@silica (PS@SiO₂) colloidal crystals. The PC films release energy by forming local fractures at a microscopic level during the straining process but the lattice spacing and effective refractive index of the local array do not change. According to the Bragg law, the structure color remains unchanged. The introduction of HPMC gave the PC films excellent tensile properties, and the maximum tensile strength reached 10 MPa. And after 100 times of stretching, bending and compression cycles, the structural color remained unchanged.

基于Zn2 +配位和羟丙基甲基纤维素的机械不变色和抗拉伸光子晶体膜

机械不变色和抗拉伸光子晶体（PC）膜，尤其是那些在变形过程中具有稳定结构颜色的膜，在可穿戴显示设备，装饰和包装中具有巨大的潜在应用。在此，通过将Zn ²⁺配位弹性材料和羟丙基甲基纤维素（HPMC）与聚苯乙烯@二氧化硅（PS @ SiO ₂）结合，制备了具有抗拉伸和变形时结构不变的PC膜。）胶体晶体。PC膜通过在应变过程中在微观水平上形成局部断裂来释放能量，但局部阵列的晶格间距和有效折射率不变。根据布拉格定律，结构颜色保持不变。HPMC的引入使PC膜具有出色的拉伸性能，最大拉伸强度达到10 MPa。经过100次拉伸，弯曲和压缩循环后，结构颜色保持不变。
