原文摘要如下：Rapid and robust response to external stimulus with large volume deformation is of big importance for the practical application of thermo-responsive photonic crystal film (TRPCF) in actuator, colorimetric sensor, and other color-related fields. Generally, decreasing the size of thermo-responsive photonic crystals and introducing micropores are considered two effective approaches to improve their responsiveness. However, they usually result in poor mechanical property which leads to optical instability. To solve these problems, a heterogeneous thermo-responsive photonic crystal film is developed here by integrating thermosensitive hydrogel matrix poly(N-Isopropylacrylamide-co-N-Methylolacrylamide) (P(NIPAM-co-NHMA)) with high-modulus but non-thermosensitive poly(acrylic acid -co-2-hydroxyethyl methacrylate (P(AA-co-HEMA)) hydrogel-based photonic nanochains (PNCs). The as-obtained TRPCF based on PNCs (TRPCF-PNC) well combines rapid response and improved mechanical property. Typically, it can complete response within 12 s from 26 to 44 oC accompanying with a larger deformation of matrix than that of PNCs. The unique rapid thermochromic mechanism of TRPCF-PNC is revealed here. Besides that, it exhibits high tensible property along PNCs orientation direction and excellent optical stability. The response time of TRPCF-PNC can conveniently modulate by changing cross-linking degree of PNCs or the content of thermosensitive component in matrix. The heterogeneous TRPCF-PNC is believed to have potential applications in artificial muscle and quick-response actuation devices.
