摘要/Abstract

摘要： 导电地质聚合物是传统地质聚合物经由导电功能相改性而发展起来的一类兼具环境友好性与多功能性的新型材料,旨在突破其导电性能瓶颈并拓展应用领域。论文通过系统梳理国内外相关研究,综述了其制备工艺、导电机理、微观结构与宏观性能之间的构效关系。研究结果表明:导电相的种类、掺量(如碳纤维逾渗阈值低至体积分数0.05%、质量分数1%石墨烯可提升电导率348倍)及分散工艺(如预混合法可降低电阻率超99%)是调控其性能的关键;通过扫描电镜(SEM)等微观分析揭示了“填料分散-界面结合-网络形成”是决定导电与力学性能的核心机制;碳基导电地质聚合物在其中表现尤为突出,展现出优异的综合性能。基于此,该材料在电磁屏蔽、智能传感与能源存储等领域展现出巨大潜力。论文最后指出了当前在分散工艺、界面调控及长效稳定性等方面面临的挑战,并对未来重点研究方向进行了展望。

Abstract: Conductive geopolymer,developed by modifying traditional geopolymer with conductive functional phases,re presents a novel class of materials that combine environmental friendliness with multifunctionality,aiming to overcome its con ductivity limitations and expand its application fields.This paper comprehensively reviews the research progress in this field,fo cusing on the preparation processes,conductivity mechanisms,and the structure-property relationships between microstructure and macroscopic properties.The results indicate that the type and dosage of conductive phase (e.g.,a low percolation thresh old of 0.05% for carbon fibers,a 348-fold increase in conductivity with 1% graphene) and the dispersion technique (e.g., pre-mixing method reducing resistivity by over 99%) are critical for performance regulation.Microscopic analysis,such as Scanning Electron Microscopy (SEM),reveals that the "filler dispersion,interface bonding,network formation" mechanism is central to determining the conductive and mechanical properties.Carbon-based conductive geopolymers,in particular,demon strate outstanding comprehensive performance.Consequently,these materials show great potential in applications such as elec tromagnetic shielding,intelligent sensing,and energy storage.Finally,this paper identifies current challenges,including disper sion techniques,interface control,and long-term stability,and outlines promising future research directions.
