▎ 摘  要

NOVELTY - Preparation of laser-induced graphene-coated conductive glass fiber mesh involves selecting carbon-containing precursor material for coating, preparing carbon precursor material-containing glass fiber paper, and irradiating laser to reduce and convert carbon precursor into laser-induced coated graphene. USE - Preparation of laser-induced graphene-coated conductive glass fiber mesh used in heavy metal adsorption, sewage treatment, water purification, electrochemical deposition, soil remediation, seawater desalination, precious metal extraction and garbage permeate treatment. ADVANTAGE - The method enables preparation of laser-induced graphene-coated conductive glass fiber mesh with excellent adsorption performance, sterilization effect and disinfection effect. Viruses and bacteria adhered to the conductive glass fiber mesh are efficiently, effectively and rapidly killed by applying voltage on both sides of the glass fiber mesh. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a conductive glass fiber mesh preparation device, which comprises a laser component, a conveying platform component, a sample turning component, a sample folding component and a control component. The laser component provides energy source for laser-induced coating graphene. The laser component comprises a laser, a light path transmission component, a laser focusing head and a motor motion system. The laser includes a semiconductor laser, an optical fiber laser and a carbon dioxide laser. The laser focusing head adjusts different processing spot size. The motor motion system controls the movement of laser focusing head on the XY plane. The motor motion system is a servo motor or a stepping motor. The conveying platform component includes three working platforms (P1-P3). A conveyor belt is provided between the working platforms. The working platform (P1) is a glass fiber paper sampling position including carbon precursor material. The working platform (P2) includes glass fiber paper including a carbon precursor material for laser-induced coating graphene processing positions, and a filter paper inversion position for double-sided laser-induced coating graphene process. The working platform (P3) is a laser-induced folding processing position of coated graphene glass fiber paper, and a sample position of the laser-induced coated graphene conductive glass fiber mesh. The sample reversing component realizes the reversal of the glass fiber paper including the carbon precursor material. The sample folding component realizes the discounting and folding processing of the laser-induced graphene-coated glass fiber paper. The control component controls the laser component, conveying platform component, sample turning component and sample folding component.
