Rice canal has carbolic accept to grow the exceedingly good physics character such as diameter comparing, tall electrical conductivity high, canal of carbolic accept rice is added to be able to form the complex and microcosmic electric network that forms by resistor, inductance and capacitance in polymer matrix. Use microcosmic and electric network to be answered to the electricity of meet an emergency, can develop sensor of composite material meet an emergency. Recently, Environment of water of key laboratory of Ministry of Education of technology of test of production process of university of southwest science and technology leaves advanced material and intelligent system groupYuan Weifeng is taughtWith Heibei industry universityDr. Huang JieyanCollaboration is in engineering field top class periodicalComposites Part B: Engineering(IF=11.322) published a problem to be the newest achievement of “Wireless Strain Sensing Using Carbon Nanotube Composite Film” . Heibei industry universityDr. Huang JieyanFor the paper the first author, university of southwest science and technologyYuan Weifeng is taughtFor newsletter writer, university of southwest science and technology is the first finishing unit of this achievement.
Use specific technology preparation carbolic accept rice provides pH indicator of canal of rice of different carbon accept / epoxy resin composite material checks sample, experimental discovery should check sample to be in be produced inductive tension by the meeting when electromagnetism is incentive, and the syntonic frequency that the to load of meet an emergency tastes correspondence of inductive voltage peak value to checking sample is influential. To announce its are wireless spread the working mechanism of feeling, this research figured the equivalent RLC circuit of composite material, subsequently theoretical analysis, imitate forecasts the rationality that made clear this equivalent RLC circuit with experimental result. Accordingly, carbolic accept rice is in charge of / what the deflection that epoxy resin composite material can pass token resonance frequency will realize meet an emergency is wireless detect, be versed in the development that regards label type as sensor of wireless meet an emergency offerred a kind of new thinking originally.
