Muqing Cao, Yizheng Tan and Huaping Xu New Journal of Chemistry; 2023, 47, 5582. In recent years, mechanochemistry of polymers, which means the reactivity of polymers under mechanical stimuli, has been widely studied and greatly developed. Among various kinds of mechano-responsive polymers, dynamic chalcogen-containing polymers have attracted more attention due to their sensitive responsiveness and precise biofunction. In this perspective, we provide an overview of mechanochemistry of dynamic chalcogen-containing polymers, including both fundamental mechanochemistry and applications. Particu...

Fuqiang Fan, Cheng Liu, Sha Wang, Jinqiu Lv, Wenze Li, Yu Fu, Huaping Xu J. Mater. Chem. C, 2019, 7, 10777-10782. An ordered pattern or a distinct texture on surfaces endows materials with specific applications, such as oil-water separation, advanced anticounterfeiting and optical devices. Conventional photolithography and surface patterning methods can form only 2D patterns, and they are also limited by the shape of a material and the required equipment. In this study, a swelling-induced 3D photopatterning (SPP) method is demonstrated to manipulate both the shape and surface pattern of a ...

Zhiyuan Fan, Huaping Xu Polym. Rev., 2020, 60, 114-143. Responsive polymeric materials that are sensitive to biological stimuli including temperature, pH, enzymes, or redox conditions have attracted research interest in recent years. Among these, reactive oxygen species (ROS)-responsive polymers are particularly appealing because of the special role of ROS in living organisms. ROS are the indicator and cause of certain diseases, and they are also important signaling molecules. ROS-responsive polymers could possess the following functions: drug carriers, ROS probes, or medications for cer...

Cheng Liu, Jiahao Xia, Shaobo Ji, Zhiyuan Fan and Huaping Xu Chem. Commun., 2019, 55, 2813 - 2816. The Se–Te bond was prepared by a metathesis reaction between diselenides and ditellurides, which could be manipulated with the presence or absence of visible light. Additionally, the apparent activation energy of the exchange process was measured to be only 28.01 kJ mol-1, explaining the high reactivity and sensitivity to light.

Fuqiang Fan, Shiqian Gao, Shaobo Ji, Yu Fu, Pengpeng Zhang and Huaping Xu  Mater. Chem. Front., 2018, 2, 2109-2115 The combination of chemotherapy and radiotherapy could not only enhances cancer treatment efficacy, but also shortens the period of the overall treatment and relieves the negative emotions of the patients during the remedy. Here, we presented a novel strategy for coordinating the chemotherapy drug CDDP with a tellurium-containing polymer, which restrained the tumour cytotoxicity of these two portions. After low dose γ-radiation, CDDP departed from the coordination complexes, and...

Shaobo Ji, Fuqiang Fan, Chenxing Sun, Ying Yu and Huaping Xu ACS Appl. Mater. Interfaces, 2017, 9, 33169-33175 Plasticity of thermoset polymers has been realized by introducing exchangeable bonds, and the plasticity is mostly triggered via heat or UV light. Visible light is a relatively mild trigger that has not been used to induce plasticity in polymer materials. Herein, thermoset polyurethanes (PUs) containing diselenide bonds are fabricated that possess visible light-induced plasticity along with shape memory behavior. A series of PUs with different diselenide bond contents were teste...
