Low-Dielectric Polymers Derived From Biomass

Abstract

Biomass-derived high-performance polymers have recently received much attention because they are easily available and renewable. More recently, researchers have been interested in low-dielectric polymers derived from biomass feedstock. These polymers display good dielectric properties and high thermostability, as well as good mechanical properties, implying that they have potential application in microelectronic industry, especially in fifth-generation communication (5G). This review summarizes recent progress in low dielectric polymers based on the biomass, including the synthesis and properties of different types of biomass resins such as epoxy resins, benzoxazine resins, benzocyclobutene resins, perfluorocyclobutane resins, cyanate eaters, polyester resins, phthalonitrile resins, and a functional maleimide.

Dual cross-linking strategy to prepare fluorine-containing poly(arylene ether nitrile) films with a low dielectric constant and ultra-low water uptake

“…With the development of ultra-large-scale integrated circuits (ULSL) with high speed and high integration in the semiconductor industry and the continued miniaturization of the size of electronic devices used in ULSL circuits, there is an urgent need for high-performance low dielectric constant (k ≤ 2.5) and ultra-low dielectric constant (k ≤ 2.0) materials. [1][2][3][4][5] Such dielectric materials reduce capacitance, resistive delay, wire-to-wire crosstalk noise and power consumption between metal interconnects, 6,7 and provides significant application prospects in interlayer dielectrics, semiconductor packaging and high-frequency, low-loss boards. [8][9][10] Compared with inorganic dielectric materials, organic polymers have a lower dielectric constant, a low density and excellent processing and molding properties.…”

Bio‐basedbenzoxazine from renewableL‐tyrosine: Synthesis, polymerization, and properties

“…Synthetic polymers, as an indispensable part of human production and life, are mainly derived from fossil resources. As a result, developing bio‐based polymers from renewable resources are rapidly evolving 1–6 . Polybenzoxazine is a promising thermoset due to its outstanding comprehensive performance such as excellent thermomechanical properties, inherent low flammability, low surface free energy, low dielectric constants, and near‐zero shrinkage upon curing 7–14 .…”

Preparation and performance of low‐dielectric benzocyclobutene resins containing dicyclopentadiene

“…Low-dielectric polymer materials have attracted increasing research attention in recent decades owing to their excellent dielectric and thermal stabilities. [5][6][7][8][9] For example, polyimide is widely used in electronic and electrical, aerospace and other fields, because of its excellent heat resistance, high mechanical strength, good solvent resistance and dielectric properties. [10][11][12] DVSBCB are a low dielectric constant material developed by Dow Chemical and widely used in IC production and high-end microelectronics.…”
