Abstract: A sensor for quantitative testing electromechanical properties and microstructure of nano-materials and a manufacturing method for the sensor are provided. The sensor comprises a suspended structure, pressure-sensitive resistor cantilevers, support beams, bimetallic strip and other components. When the bimetallic strip produces bending deformation, one of the pressure-sensitive resistor cantilevers is actuated and then stretches the low-dimensional nano-materials which drive the other pressure-sensitive resistor cantilever to bend. Through signal changes are outputted by the Wheatstone bridge, the variable stresses of low-dimensional nano-materials are obtained. Meanwhile, the variable strains of low-dimensional nano-materials are obtained by the horizontal displacements between two cantilevers, so the stress-strain curves of low-dimensional nano-materials are worked out. When the low-dimensional nano-materials are measured in the power state, the voltage-current curves are also obtained.

Abstract: In certain examples, this invention provides an inorganic composite binder with high-temperature resistance comprising 5-12% of aluminum hydroxide, 15-35% of phosphoric acid, 0.1-1% of rare earth oxide, 5-20% of silica sol, 1-15% of polyaluminum phosphate, 1-5% of borax, based on the total weight of said binder, and the rest being water, and a method for producing the same. The binder of the example can be used in temporary protective coating layer such as the high temperature coating and the high temperature antioxidation coating layer during the heat treatment of the metal workpiece, can make it possible to form an antioxidation coating layer immediately upon directly spraying the coating onto the substrate surface of the metal at high temperature of 400-1000° C.
