Cement-based sensing material as well as preparation method and application thereof
The invention discloses a cement-based sensing material as well as a preparation method and application thereof. The cement-based sensing material comprises MXene, DOAS powder and a gel material, the DOAS powder is prepared from the following components in percentage by mass: 20 percent to 30 percent of bis (2-ethylhexyl) sodium sulfosuccinate, 15 percent to 30 percent of 2-octenyl-1-yl succinic anhydride, 15 percent to 30 percent of 3-aminophenylboronic acid and 25 percent to 35 percent of a surfactant. The material is applied to detection of chloride ions in concrete. According to the invention, a conductive network is constructed by using DOAS dispersed MXene, and the conductive network has good conductivity and sensitivity, stable performance and good durability, and can be used in concrete construction engineering for a long time; cement and other cementing materials are used as main components, the expansion coefficient is close to that of concrete, the compatibility is good, and the concrete can be applied to various concrete buildings.
本发明公开了一种水泥基传感材料及其制备方法与应用，该材料包括MXene、DOAS粉末和凝胶材料；DOAS粉末按质量百分比包括以下组分：二(2‑乙基己基)琥珀酸酯磺酸钠20％～30％、2‑辛烯基‑1‑基琥珀酸酐15％～30％、3‑氨基苯硼酸15％～30％、表面活性剂25％～35％。本发明的材料应用于混凝土中氯离子检测。本发明通过DOAS分散的MXene来构建导电网络，具有良好的导电性与灵敏度，并且性能稳定、耐久性好、可以长时间服务于混凝土建筑工程中；以水泥等胶凝材料为主要组分，其膨胀系数与混凝土接近，相容性好，可以应用于各类混凝建筑。
