Through adoption of the electron beam lithography technology and the reactive ion etch technology, a rigid template with a nanometer magnitude pattern is etched and taken as a filling template according to photonic crystal structure parameters designed in advance, high-elastic gel with good mechanical property is taken as matrix materials, and a visco-elastic polymer is taken as filling materials; and through the mode of the filling template, the photonic crystal pattern designed in advance in the high fidelity mode is transferred into the visco-elastic polymer, and the nanometer magnitude and structure controllable photonic crystal materials with force responsiveness are prepared through spin coating, stacking and the like. Compared to the current technology, the preparation method of force responsiveness nanometer magnitude photonic crystal materials is simple in technology and short in flow, technology parameters are easy to control, the template can be reused, the precision of products is high in level, the quality is stable and reliable, and the cost is low, etc.

Description

Technical field [0001] The invention relates to a method for preparing a photonic crystal material, in particular to a method for preparing a force-responsive nano-scale photonic crystal material. Background technique [0002] The preparation of the force-responsive photonic crystal material is to fill the nano-scale photonic crystal lattice gap with a highly elastic gel material with excellent mechanical properties. Through mechanical stretching or compression, the highly elastic polymer network structure will increase or decrease the photonic crystal lattice spacing, resulting in the change of diffraction wavelength and structural color, realizing the transformation of physical deformation into optical performance changes. Sensing function. [0003] Studies have shown that the multi-layer structure composed of highly elastic gel and viscoelastic polymer with nano-scale photonic crystal structure has good mechanical response properties. This kind of photonic crystal can not only...
