中文摘要： 研究开发低添加量、热稳定性高、更高效的环保阻燃剂，是近年来阻燃领域重点研究目标之一。已有研究表明，金属化合物与环保膨胀型阻燃剂复配使用，可实现体系阻燃效率的提高，但容易出现分散不均匀、相容性差等问题，且金属化合物的催化阻燃机理研究尚不完善。本项目拟通过巧妙的分子设计，将具有催化阻燃功能的金属元素同含磷、氮元素的膨胀型阻燃剂结构以有机配位的方式相结合，制备具有自催化阻燃效果的金属配位膨胀型阻燃剂，使其可以独立作为阻燃剂，结合金属催化阻燃和膨胀阻燃优点，有望达到提高阻燃效率、降低阻燃剂添加量的目的。在机理研究方面，不仅从传统的角度(热降解过程中气相和凝聚相产物结构、残炭的物理化学结构等方面)进行阻燃机制的研究，而且从更微观的分子角度，研究配位构型、键长键角、价态、位阻效应等对材料热、阻燃性能的影响，阐明金属元素、有机配体及分子构型之间的协同阻燃机制，为高效无卤化阻燃体系研究提供重要的理论依据。

英文摘要： To design and develop environmentally friendly flame retardant with lower loading, high stability and high performance has attracted more attention in recent years in flame retardant field. Studies have shown that the cooperation of the metal compounds and intumescent flame retardant through physical blending could achieve an increased flame retardant efficiency. However, it would result in problems such as heterogeneous dispersion and poor compatibility with matrix. Moreover, study on the catalysis mechanism of flame retardancy of metal compound is still incomplete. Therefore, in this work, a series of self-catalytic intumescent flame retardants with metal-organic coordination are synthesized, which combined the metal element and intumescent flame retardant element such as phosphorous and nitrogen by organic coordination through a smart molecular design and can act as flame retardants independently. The integration of catalysis and imtumesecent flame retardancy in one macular will be hopeful to promote the efficiency of flame retardancy and lower the addition of flame retardants. As for flame retardant mechanism, the study will be carried out not only from the traditional perspective to analyze the structure of the gas and condensed phase products, the physical and chemical structure of residue char and etc, bu
