Abstract A new-type of composite combined by helical polysilane (HPS) and hollow spherical indium oxide (In 2 O 3 ) was designed and fabricated via solution blending. The hollow spheres constructed by In 2 O 3 particles were synthesized via a facile hydrothermal route where it demonstrated larger surface area, enabling the combination of HPS and In 2 O 3 more easily. Meanwhile, the synergetic effect between functional group of HPS and surface hydroxyl of In 2 O 3 improve the reduction of infrared emission. Consequently, the composite shows a superior low infrared emissivity performance at the value of 0.416 (8–14 μm), and the covering of HPS make the composite disperse well in the polar reagent. This work develops a feasible strategy that utilizes metallic oxide to design and synthesize hollow spherical matrix for preparing the low infrared emissivity materials.
