Among them, polyimide (PI) has become an important interlayer dielectric material because of its excellent comprehensive properties. However, in order to meet the needs high-frequency and high-speed circuits for 5 G networks, it will be necessary to further reduce the dielectric constant and dielectric loss of PI. PI is widely used as a flexible dielectric material due to its excellent electrical insulation properties (dielectric constant ≈ 3.0–4.0, dielectric loss ≈ 0.02), mechanical properties, and thermal resistance. However, further reduction in the dielectric constant will be needed in order for PI-based materials to better meet the current high integration development needs of the microelectronics industry.

Dry reforming is a challenging reaction to scale-up due to its high endothermic and coke formation nature. Microwave has gained interest in the past years as a superior heating mechanism in catalytic reactions due to its capacity in enhancing conversions of reactants and selectivity of products, and suppression of coke formation.
