“…As mentioned above, the balance of permittivity and permeability plays the main role with the microwave absorption properties: We would employ conductive polymers, such as polyaniline (PANI) to improve permittivity. In general, conductive polymers have attracted the attention of the scientific community for their many interesting qualities such as easy synthesis, low cost, lightweight, environmental stability, and high conductivity 29‐33 . In particular, PANI shows exceptionally high electrical conductivity, good thermal stability, and nontoxicity 34 .…”

Recently, there has been an increasing demand in the electronic equipment industry such as mobile phones, laptop computers, and tablets, modems and antennas, which require the shift to centimeter-scale wavelengths in the microwave range . The growth of devices functioning at this GHz frequency range creates the serious risk of electromagnetic interference (EMI) problems. Furthermore, health concern issues are being raised all over the world due to electromagnetic radiation, which could affect human health, resulting in memory loss, fatigue, lack of sleep, headaches, etc. 1 In order to protect biological systems and electronic equipment against potential damage due to electromagnetic (EM) pollution, especially caused by the explosive utilization of gigahertz (GHz) EM waves, a functional material with low density, strong absorption, thin thickness, and wide absorption frequency range is intensively pursued. 2-4 Nowadays, researchers have been attempting to study all kinds of materials which can absorb EM wave by converting EM energy into thermal energy or dissipating them through interference, which depend on their dielectric loss and/or magnetic loss ability. 5 The balance of permittivity and permeability, which is called EM wave impedance matching, is beneficial for

“…It was found that there is an increase in the dielectric value with the rise of the carbon nanotube's contents. Reduced graphene oxide (rGO) improved the dielectric properties of polyaniline (PANI)/calcium copper titanate (CaCu3Ti4O12) [188]. It can be also improved PVP-PVA [189], and starch [190].…”

Biodegradable polymers exhibit shortcomings, including low thermal stability and electrical conductivity. These challenges limit the broad applications of several applications, such as electronic devices. They show suitable dielectric, thermal, and electrical conductivity compared to the biodegradable polymer alone. Several methods can improve biodegradable polymers' dielectric, thermal, and electric conductivity, including co-polymerization, blending, and cross-linking with other polymers. Furthermore, the formation of nanocomposites seems to be the most effective method to improve the properties and performance of biodegradable polymers. This book chapter summarized biodegradable polymers' dielectric, thermal, and electrical conductivity. Biodegradable polymers nanocomposites consisting of polymers blend, inorganic, and other nanomaterials were discussed.
