Overexposure to ultraviolet (UV) with high energy can not only hurt human skin but also accelerate the degradation of organic matter. Hence, the preparation of polymer‐based UV‐shielding nanocomposites has attracted substantial attention due to the low cost, easy processing and wide applications. Notably, the highly efficient UV‐shielding polymer nanocomposites are still hindered by the agglomeration of inorganic anti‐UV nanoparticles (Nps) in polymer matrix and the narrow absorption range of UV‐shielding agents. To overcome the aforementioned bottlenecks, surface engineering of anti‐UV Nps including organic modification and inorganic hybridization has been extensively employed to enhance the UV‐shielding efficiency of composites. Herein, to deliver the readers a comprehensive understanding of the surface engineering of anti‐UV Nps, we systematically summarize the recent advances in surface organic modification and inorganic hybridization related to anti‐UV Nps. The UV‐shielding mechanism and the factors affecting UV‐shielding efficiency of polymer nanocomposites are also discussed. Finally, perspectives on remaining challenges and future development of highly efficient UV‐shielding composites are outlined.

用于高效紫外线防护复合材料的纳米粒子表面工程

过度暴露于高能量的紫外线(UV)不仅会伤害人体皮肤,还会加速有机物的降解。因此,基于聚合物的紫外线防护纳米复合材料的制备因其低成本,易于加工和广泛应用而备受关注。值得注意的是,高效的紫外线防护聚合物纳米复合材料仍然受到聚合物基体中无机抗紫外线纳米颗粒(Nps)的团聚和紫外线防护剂吸收范围狭窄的阻碍。为克服上述瓶颈,抗紫外线Nps的表面工程(包括有机改性和无机杂交)已被广泛采用,以提高复合材料的紫外线防护效率。在此,为了使读者全面了解抗紫外线Nps的表面工程,我们系统地总结了与抗UV Nps相关的表面有机修饰和无机杂交的最新进展。还讨论了聚合物纳米复合材料的紫外线屏蔽机理和影响紫外线屏蔽效率的因素。最后,概述了有关高效紫外线防护复合材料的剩余挑战和未来发展的观点。
