Titanium dioxide (TiO) had the potential to be a desensitizing material, but its inherent characteristics presented challenges for coating on energetic materials. To enhance the interfacial interactions of energetic materials and TiO, the surface of TiO was modified with biomass tannic acid (TA) to prepare the core-shell (hexanitrohexaazaisowurtzitane) CL-20@TA-TiO energetic composites. Various characterization techniques were used to investigate the thermal performance, impact sensitivity, structure, and surface morphology of CL-20@TA-TiO. The protective layer formed by the TA-TiO coating on the surface of CL-20, thus protecting the material from external stimulation. The results indicated that the organic-inorganic core-shell energetic composites prepared with biomass TA as the interface layer exhibited outstanding performance.
二氧化钛（TiO）有可能成为一种脱敏材料，但它的固有特性给在含能材料上进行涂层带来了挑战。为了增强含能材料和 TiO 的界面相互作用，用生物质单宁酸（TA）对 TiO 的表面进行改性，制备了核壳（六硝基六氮杂异伍兹烷）CL-20@TA-TiO 含能复合材料。采用各种表征技术研究了 CL-20@TA-TiO 的热性能、撞击感度、结构和表面形貌。TA-TiO 在 CL-20 表面形成的保护层，从而保护材料免受外部刺激。结果表明，用生物质 TA 作为界面层制备的有机-无机核壳含能复合材料表现出优异的性能。
