Abstract

The detrimental effects of ultraviolet (UV) and electromagnetic (EM) radiation on human health and physiological functions are well documented. The development of efficient shielding materials to mitigate these effects is therefore an urgent necessity. In this study, Zn/Ti-LDH@Ce/Fe-MOF@PPy composites were successfully prepared by hydrothermal synthesis and interfacial polymerisation. The properties of the composites were compared and analysed with those of pure Zn/Ti-LDH and Ce/Fe-MOF, and the results show that the prepared materials have excellent comprehensive properties, with a broad EAB of 5.2 GHz and a RL_min of −46.2 dB at 14.8 GHz at the thickness of 3 mm, while exhibiting excellent UV shielding capability.The present study offers novel concepts and efficacious methodologies for the engineering of high-performance microwave absorbing and UV shielding materials.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
