Preparation and Characterization of Electrospun Fluoro-Containing Poly(imide-benzoxazole) Nano-Fibrous Membranes with Low Dielectric Constants and High Thermal Stability
Abstract:The rapid development of advanced high-frequency mobile communication techniques has advanced urgent requirements for polymer materials with high-temperature resistance and good dielectric properties, including low dielectric constants (low-Dk) and low dielectric dissipation factors (low-Df). The relatively poor dielectric properties of common polymer candidates, such as standard polyimides (PIs) greatly limited their application in high-frequency areas. In the current work, benzoxazole units were successfully… Show more
“…Some examples include LCP, [20][21][22] modied epoxies using active esters as curing agents [23][24][25][26][27] and uoro-containing polymers. [28][29][30][31] However, there are a few species suitable for application in communication at high speed and high frequency. On the other hand, although commercial PTFE and its derivatives 32 have been used in the electronics and microelectronics industries for many years, their processability and poor thermostability block their use.…”
A facile one-pot conversion of the bio-based magnolol gave a functional monomer with curable benzocyclobutene group, which was then thermally polymerized to form a cross-linked resin, displaying a very low...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
