Abstract As a result of the energy deposition of ionizing radiation in organic polymers and in organic compounds in general, excited and ionized species are formed. The latter can readily react with emitted electrons to form excited species that will eventually lead to macromolecular defects and gas emission - their counterpart. Charges from ionized species and excitations can also be transferred, and trapped, far from their creation sites before leading to defects creation. In dense materials submitted to irradiation, excitations, charge transfer or mass transport from one molecule to the other has been proven to happen since the early 1930’s in organic molecules mixtures and the 1950’s in polymers. Radical stemming from the evolution of the excited molecules, which results either from direct energy deposition by the radiations or from the electron-hole recombination, can also migrate before being trapped or reacting, on a site far from its creation site. Radical, excitation, electron and hole transfers are gathered in the generic term of energy transfer. In this review is presented an overview on the research performed in this field. We evaluate the influence of different parameters that can alter the efficiency of energy transfer: these can be related to the polymer composition (chemical structure of the molecules composing the monomers or the additives inserted in the bulk) or to the irradiation characteristics (radiation type among ionizing radiations, dose and temperature for example). To get rid of the complexity brought by the polymer structure and the existence of different levels of organization, polymers are sometimes modelled by molecules, either pure or as mixtures. To take this into account, some studies on energy transfer in molecule mixtures are also presented.

接受电离辐射的聚合物中的能量转移：综述

摘要 由于电离辐射在有机聚合物和一般有机化合物中的能量沉积，会形成激发态和电离态物质。后者可以很容易地与发射的电子反应形成激发态，最终导致大分子缺陷和气体发射——它们的对应物。来自电离物质和激发的电荷也可以在导致缺陷产生之前远离它们的产生位置转移和捕获。在经受辐照的致密材料中，自 1930 年代早期的有机分子混合物和 1950 年代的聚合物已证明，从一个分子到另一个分子的激发、电荷转移或质量传输发生了。自由基源于激发分子的进化，由辐射的直接能量沉积或电子-空穴复合产生的结果，也可以在被捕获或反应之前在远离其产生地点的地点迁移。自由基转移、激发转移、电子转移和空穴转移统称为能量转移。在这篇综述中，概述了在该领域进行的研究。我们评估了可以改变能量转移效率的不同参数的影响：这些参数可能与聚合物成分（构成单体的分子的化学结构或插入本体的添加剂）或辐射特性（辐射类型）有关。例如电离辐射、剂量和温度）。为了摆脱聚合物结构带来的复杂性和不同层次组织的存在，聚合物有时以分子建模，无论是纯分子还是混合物。考虑到这一点，还介绍了一些关于分子混合物中能量转移的研究。
