采用细乳液界面缩聚法制备了以三甘醇二甲基丙烯酸酯（TEGDMA）为芯材、聚氨酯为壁材的自愈合粘接树脂纳米胶囊。考察了表面活性剂和助稳定剂浓度对纳米胶囊粒径和稳定性的影响。用光散射粒度分析仪测定了纳米胶囊的粒径及其多分散性。当SDS浓度从2.5wt%增加到10wt%时，粒径从340.5nm减小到258.3nm，PDI从0.210减小到0.111。随着HD质量分数的增加，粒径和PDI均减小，当HD质量分数达到10%时，粒径为258.0nm，PDI为0.130。SDS和HD在含TEGDMA纳米胶囊的合成中起着重要的作用。通过改变表面活性剂和助稳定剂的浓度，可以合成各种各样的纳米胶囊尺寸。初步研究了纳米胶囊的性能和工艺参数，为纳米胶囊在自修复粘接树脂中的应用奠定了基础。
Nanocapsules with triethylene glycol dimethacrylate (TEGDMA) as core material and polyurethane as wall material used for self-healing bonding resin were prepared by interfacial polycondensation in miniemulsion. The influence of surfactant and costabilizer concentration on nanocapsules size and stability of nanocapsules was investigated. The size and its polydispersity of the nanocapsules were measured by light-scattering particle size analyzer. When the concentration of SDS were increased from 2.5wt% to 10wt%, the size decreases from 340.5 nm to 258.3 nm, PDI decreased from 0.210 to 0.111. As the concentration of HD increased, the size and PDI were both decreased, When reaching 10wt%, the size was 258.0 nm, PDI was 0.130. SDS and HD play important effect in synthesis of Nanocapsules containing TEGDMA. By changing the surfactant and costabilizer concentration it was possible to synthesize a wide variety of nanocapsules sizes. The performance and technical parameters of nanocapsules had been researched preliminarily, which built the solid foundation for the application to the self-repairing bonding resin.
