Abstract: Polyimide with high dielectric constant and breakdown strength is synthesized via tin complexation of the polyamide acid precursor. Sn–O bonds with high atomic polarizability are intended to enhance the ionic polarization without sacrificing bandgap.

“…The concept is to combine and leverage the physical properties of organic polymer dielectrics and inorganic metal oxide dielectrics into a single component. Various hybrid dielectrics have been reported for flexible applications, including organometallic polymer dielectrics, organic–inorganic nanocomposite dielectrics, and bilayer organic–inorganic dielectrics. For example, flexible MoS 2 FETs were fabricated with SU-8 and ALD grown Al 2 O 3 bilayer gate dielectrics (Figure d) . The capacitance of the 630 nm-thick hybrid dielectric is 4.6 nF cm –2 , much higher than the capacitance of SU-8 alone …”

“…[12][13][14][15] Nonetheless, the polar imide group endows the polyimide with a relatively high dielectric constant (around 3.5), which does not meet the requirements of the microelectronics industry. 16 From the perspective of molecular structure design, there are two main strategies to lower the dielectric constant in polyimides: one is introducing large pendant groups to decrease the packing density of the polyimide chains; 5,[17][18][19] the other is increasing the amount of fluorine atoms on the polyimide backbone to reduce the polarization ability. [20][21][22] These two strategies could also be combined to further decrease the dielectric constant.…”
