Research progress of low dielectric constant polymer materials

Abstract

The advent of high frequency communication era presents new challenges for further development of dielectric polymer materials. In the field of communication, efficient signal transmission is critical. The lower the dielectric constant of the dielectric material used, the lower the signal delay and the higher the signal fidelity. The preparation of polymer materials with low dielectric constant or reduce the dielectric constant of polymer materials becomes a key research topic. Summarizing past progress and providing perspective, this paper primarily discusses the intrinsic low dielectric polymers, fluorine doped low dielectric polymers, and microporous low dielectric polymers, while predicting the research trend of low dielectric materials.

High-Dielectric PVP@PANI/PDMS Composites Fabricated via an Electric Field-Assisted Approach

“…This is because the presence of PVP between conductive PANI in aligned channels can block the formation of conductive paths and minimize the increase in dielectric loss tangent caused by the leakage of current. The insulated PVP shell reduces the dielectric loss tangent, which acts as a dielectric layer to suppress the current leakage between PANI in direct contact [ 40 , 41 , 42 , 43 ].…”

Polyimide/crown ether composite film with low dielectric constant and low dielectric loss for high signal transmission

“…13 Therefore, the optimization of dielectric properties requires that the PI polymer chains contain non-polar functional groups. 14 In addition, the location of the polar functional groups is also significant. The polar group has a greater effect on the dielectric properties, if it is on the side chain of the polymer, especially on the flexible polar group with strong migration rate.…”

Design and Synthesis of Low Dielectric Poly(aryl ether ketone) from Incorporation Bulky Fluorene Groups and Regular Hydroquinone Structure

“…5G communication technology plays a crucial role in information transmission. At the same time, because 5G communication requires more extensive data transmission, faster transmission speeds, and higher frequencies, it poses new challenges for further developing a low dielectric constant ( D k ) and low dielectric loss ( D f ) polymer materials in communication equipment. − …”
