Abstract: This article briefly describes the effects of low -orbit space environmental factors such as atomic oxygen, ultraviolet radiation, charged particle irradiation and thermal cycling on material properties. The synergistic effects of ultraviolet radiation, charged particle irradiation and temperature cycling on the interaction of atomic oxygen with materials are reviewed. It provides a reference for ground simulation experiments of material space environmental effects, and also provides a basis for the study of multi-factor synergistic effects of materials.

Key words: atomic oxygen, ultraviolet, charged particles, thermal cycling, synergistic effect
