Recent developments in sustainable EM wave shielding composites- review

Due to technological advancements, there is tremendous demand for electronic gadgets essential for daily life. These gadgets emit electromagnetic radiation (EMR), harming the health of people in regular contact with these gadgets and creating electromagnetic interference (EMI) in neighboring electronic devices. EMI deteriorates the intended functions of the gadgets. Hence, electronic devices require EM radiation shielding. In this context, synthetic polymer composites become alternative materials to metal due to many advantages. However, synthetic polymer composites are non-degradable, and disposal once after usage is problematic. From this point of view, researchers further proposed biodegradable EM radiation shielding materials. In this regard, the advanced status of research on biodegradable EM radiation shielding authors has been presented in recent research reviews in this article. Mainly, the EM radiation shielding mechanisms and different types of bio-degradable EM radiation shielding materials recently developed by various researchers are reported. The salient features of the research review and the scope for further research are also discussed.
