Polyimide complexes with high dielectric performance: toward polymer film capacitor applications

Abstract

Novel polyimide–copper complexes (PICuCs) were prepared by polymerization, complexation and imidization of a newly synthesized bipyridine-containing diamine monomer. They showed high dielectric performance, and excellent mechanical and thermal properties.

Crown ether-containing polyimides with high dielectric constant

“…4b). The peak a could at 341-343 C could be attributed to the T g of PI lms, which was much higher than the bipyrimidine-containing PIs (291 C), 19 bipyridine-containing PIs (285 C), 20 and pyrimidine-containing co-PIs (262 C). 27 Due to the large amount of crown ether-groups, the PI molecular chains also exhibited a secondary kinetic movements, which led to the appearance of the peak b.…”

“…For example, Peng et al incorporated metals (Yb and Cu) to complex PI molecules containing bipyrimidine or bipyridine units. 19,20 Because of the increased polarity from the incorporation of metals, the obtained PI-metal complexes achieved high dielectric constant of more than 100. However, the synthesis of the bipyrimidine-or bipyridine-containing diamine monomer was too complicated and time consuming.…”

The Potential Barrier and Thermal Stability Dependence on PI Thickness of Al/PI/c-Si Schottky Diode

“…Polyimide has become an attractive compound in microelectronics applications, because of its high operating temperature, high adhesion to substrate, and high thermal stability, compared with those of common polymers [3,6].…”

Investigation of thermal and fluorescent properties of benzoxazole-linked triphenylamine-based co-polyimides

“…Aromatic polyimides is a well-known class of high-performance materials because of their outstanding properties 1 –3 and find numerous industrial applications such as dielectric films, photoresists 4 –6 membranes for gas separation, 7 matrices for high-temperature application, 8 in the field of adhesive, 9 automobile, aerospace, 10 and fuel cells. 9 –11 Among optoelectronic device applications, polyimides have attracted tremendous attention such as light-emitting diodes, memory devices, electrochromic devices, and photovoltaics.…”
