Ordered Alignment of Liquid Crystalline Graphene Fluoride for Significantly Enhancing Thermal Conductivities of Liquid Crystalline Polyimide Composite Films

“…It is attributed to the fact that ordered alignment of LC-GeF fillers forms a complete in-plane carbon layer network, which further limits the rotation space of the LC-PI molecular chains. 59 It can be seen from Figure 7b that the T HRI (266.6 °C) of pure PI film is slightly higher than that of pure LC-PI film (262.4 °C), which is due to the fact that a higher proportion of benzene rings in the molecular chains of PI molecular chain brings about slightly higher thermal stability. The T HRI (277.6 °C) of 15 wt % GeF/ LC-PI composite film is significantly higher than that of pure LC-PI film.…”

“…The T g of 15 wt % LC-GeF/LC-PI composite film is 349.2 °C, which is 16.4, 19.9, and 3.4 °C higher than the pure PI film, pure LC-PI film, and 15 wt % GeF/LC-PI composite film, respectively. It is attributed to the fact that ordered alignment of LC-GeF fillers forms a complete in-plane carbon layer network, which further limits the rotation space of the LC-PI molecular chains .

Multifunctional Polyimides for Resistive Switching Memory Devices Based on Flexible Transparent Polyimide--AgNWs Hybrid Electrodes

“…[14][15][16] Polymer memory materials can store data through the conversion between the low and high current states between two electrodes by the applied voltage, which can be assigned as "0" and "1" or "OFF" state and "ON" state. [17][18][19][20][21] In recent years, functional polyimides (PIs) are regarded as the most promising polymeric memory materials due to their excellent thermal resistance [22] , chemical stability [23] , mechanical durability [24] and flexibility [25] . More importantly, PIs with the special donor-acceptor (D-A) type molecular structures exhibiting stronger intramolecular and intermolecular charge transfer (CT) effects are more promising for the flexible memory devices.…”

Multifunctional polyimides for resistive switching memory devices based on flexible transparent polyimide–silver nanowires hybrid electrodes

“…To meet the increasing requirement of flexible RRAM devices, polymers as the active layer are more favorable than other organic materials due to their low cost, intrinsic flexibility and large area fabricating capability 14–16 . Polymer memory materials can store electronic data through the conversion between the low and high current states between two electrodes by the applied voltage, which can be assigned as “0” and “1” or “OFF” state and “ON” state 17–21 . In recent years, functional polyimides (PIs) were regarded as the most promising polymeric electronic memory materials due to their excellent thermal resistance, 22 chemical stability, 23 mechanical durability, 24 and flexibility 25 .…”
