摘　　要：为了模拟和解释材料在激光冲击产生的高应变率和压力下的实验现象,物理实验对状态方程实验靶多层材料之间的胶层厚度提出了亚微米级的需求。针对现有复合方法的不足,本文采用引发式化学气相沉积方法制备固体原胶薄膜,并采用液相活化方法对原胶薄膜进行活化和固化,实现了状态方程实验靶的亚微米级无损胶连复合。采用多种表征技术对纳米胶连复合样品的胶层厚度及形貌进行表征,胶层厚度为亚微米级,最薄时仅300 nm。本文所报道的纳米胶连复合方法能为激光加载压缩物理实验的精度提高和实验结果的准确解释提供制靶技术保障。Laser loading compression is one of the main research topics in the field of inertial confinement fusion.In order to simulate and explain the experimental phenomena of materials under high strain rates and pressures generated by laser shock,the submicron requirements for the adhesive layer thickness between the target multilayer materials in the state equation experiment were proposed in the physical experiments.Compared with the existing recombination methods,a novel adhesive recombination was reported in this paper.The poly glycidyl methacrylate(pGMA)film was prepared by initiating chemical vapor deposition method,and the liquid phase activation method was used to activate and cure the solid adhesive film.The submicron lossless bonding recombination of the state equation test target could be realized.In the activation process of pGMA film,the liquid phase activation method proposed in this paper will greatly improve the connection strength of multilayer materials without changing the thickness of the adhesive layer,which has not been reported.The thickness and morphology of the pGMA film were characterized,and the influence of process parameters on the film thickness was discussed.The deposition rate of pGMA film is about 10 nm/min in this paper.The white light confocal technology was used to indirectly measure the adhesive layer thickness of some nanoglue bonding samples.For the materials such as hydrocarbon and high-density carbon,the adhesive layer section of the nanoglue bonding samples was prepared by means of metallographic sample preparation combined with ion beam etching,and the adhesive layer thickness was directly characterized by scanning electron microscopy.The above results show that the adhesive layer thickness of the nanoglue bonding samples is submicron.And the thinnest adhesive layer of the nanoglue bonding samples is only 300 nm.The morphology of adhesive layer about the nanoglue bonding samples was characterized by optical microscope.The nanoadhesive layer connected the multilayer materials t
