ABSTRACT
Polymer foams are vital as they span a wide range of domains for a wide range of applications. They are used in several different industries, including aircraft, bedding, structural applications, electronics, and so on. Because they are non-biodegradable, their use is being curtailed to address environmental issues. There has been a flurry of studies on biodegradable foams, which are made from biopolymers. Furthermore, the monomers are attempting to be taken from biodegradable sources to improve their biodegradability. This chapter focuses on the most recent advancements in polymer foams and their applications in the electrical industry, including supercapacitors (SCs), electromagnetic interference (EMI) shielding, Human electroencephalography (EEG), acoustic applications, and energy absorption.
