Highly Dispersible Ternary Composites with High Transparency and Ultra Low Dielectric Constants Based on Hyperbranched Polyimide with Organosilane Termini and Cross-linked Polyimide with Silica

Autor: Shinji Ando, Xiaogong Wang, Seongku Kim

Publikováno v: RSC Advances. 5(Issue 119):98419-98428

Flexible insulating materials that are both thermally and mechanically stable, highly transparent, and have low dielectric constants are highly desirable for electronic applications. With these technical needs, a highly disperse inorganic matrix is t

Highly Transparent Triethoxysilane-Terminated Copolyimide and Its SiO2 Composite with Enhanced Thermal Stability and Reduced Thermal Expansion

Autor: Seongku Kim, Shinji Ando, Xingyuan Wang, Xiaogong Wang

Publikováno v: European Polymer Journal. 64:206-214

A highly transparent and colorless copolyimide was synthesized to contain electron withdrawing sulfone and fluorine groups. Then, the triethoxysilane terminal groups were introduced by reacting the anhydride end groups of the polymer with (3-aminopro

Ternary composites of linear and hyperbranched polyimides with nanoscale silica for low dielectric constant, high transparency, and high thermal stability

Autor: Seongku Kim, Xiaogong Wang, Shinji Ando

Publikováno v: RSC Advances. 5:40046-40054

A new series of ternary polyimide–silica composites was developed to obtain polymer films with low dielectric constant, high optical transparency, and good thermal stability. By using a linear polyamic acid with triethoxysilane termini and a hyperb

Hybrid Ternary Composites of Hyperbranched and Linear Polyimides with SiO2: A Research for Low Dielectric Constant and Optimized Properties

Autor: Shinji Ando, Seongku Kim, Xiaogong Wang, Xingyuan Wang

Publikováno v: RSC Advances. 4(Issue 80):42737-42746

Based on a hydroxyl-terminated hyperbranched polyimide (HBPIBPADA-TAP(OH)), two series of hybrid ternary composites composed of a linear polyimide (PI6FDA-APB), HBPIBPADA-TAP(OH) (10% and 20%), and various concentrations of SiO2 were fabricated by so

Low Dielectric and Thermally Stable Hybrid Ternary Composites of Hyperbranched and Linear Polyimides with SiO2

Autor: Xingyuan Wang, Xiaogong Wang, Shinji Ando, Seongku Kim

Publikováno v: RSC Advances. 4:27267-27276

A hydroxyl-terminated hyperbranched polyimide was synthesized via the A2 + B3 reaction between dianhydride and triamine monomers. The hydroxyl groups at the peripheral positions were then introduced by modification of the anhydride end groups via a r
