NOVELTY - Temperature-sensitive PCR thin-walled tube comprises PCR thin-walled tube whose surface is coated with a temperature-sensitive coating formed by a heat-conducting component. The heat-conducting component includes component a and component B. The component A includes a thermally conductive filler. The thermally conductive filler includes graphene oxide, modified graphene oxide, graphite, carbon nanotubes, boron nitride, aluminum oxide, or zinc oxide. The modified graphene oxide is prepared by esterifying modified graphene oxide with oxygen fluoride. The thermal conductivity of the PCR thin-walled tube is higher than 0.85 W/m.k. USE - Used as temperature-sensitive PCR thin-walled tube ADVANTAGE - The temperature sensitive PCR thin walled tube has excellent heat-conducting performance, waterproof and antifouling property, coating adhesive force and biological corrosion resistance, and is capable of quickly heating to the target temperature according to the change of the temperature.
