1. the mould of plastics for the detection of molten plastic water content, it is characterized in that, the cover half part of described mould of plastics is provided with moisture sensor module, and this moisture sensor module includes the heavy doping silicon chip (1) laid successively from top to bottom, the SiO being close to heavy doping silicon chip (1)2Layer (2), carbon nanotube layer (4), be positioned at SiO2Bottom electrode (3) between layer (2) and the upper electrode (5) that is positioned on carbon nanotube layer (4), described carbon nanotube layer (4) is grown on SiO2On layer (2);

  • Described bottom electrode (3) is metallic film, described metallic film be followed successively by from inside to outside have the Cr layer of adhesion, conductive and heat-conductive Cu layer and as the Au layer of electrode layer, the thickness of described Cr layer, Cu layer and Au layer is followed successively by 50nm, 250nm and 500nm;

    Described carbon nanotube layer (4) adopts catalyst and/or photoetching process to realize the growth of its localization, described carbon nanotube layer (4) using plasma after growth makes it produce hydroxyl modified, and carbon nanotube layer (4) have passed through the process of acetic acid and the hydrogen peroxide mixed solution adding trace tungsten powder before plasma hydroxyl modified;

    The surface of described metallic film is glued with the bacterial enzyme rete of sensing bacterial growth, and this bacterial enzyme rete and metallic film collectively form the antibacterial wet sensitive sensor of sensing moisture;

    Described bottom electrode (3) and upper electrode (5) are connected to a micro-control processor for connecting with client communication。
