Polycondensation as a Versatile Synthetic Route to Aliphatic Polycarbonates for Solid Polymer Electrolytes

Innovative Polymers for Next‐Generation Batteries

“…[13] Polycarbonate SPEs showed similar ionic conductivity values at high temperature but superior at room temperature as well as higher lithium transference numbers (T Li ≥ 0.5) than PEO which has allowed the room temperature operation of lithium-ion batteries. In Figure 3 we show some chemical structures that we recently reported synthesized polycondensation [14] as well as step-growth using CO 2 as reagent, respectively. [15] A popular approach to further improve lithium transport numbers (T Li+ ≥ 0.8) consists of anchoring the negatively charged ion to the polymeric chain, named then as singleion conducting polymer electrolytes (SIPEs).…”

Preparation of Light‐Responsive Aliphatic Polycarbonate via Versatile Polycondensation for Controlled Degradation

“…Polycondensation of aliphatic diols and diphenyl or dimethyl carbonate (DPC or DMC) is a versatile strategy for the large‐scale preparation of APCs and not limited to carbon atom numbers between the carbonate linkage. Polycondensation of linear diols and DMC or DPC using alkali‐metal catalysts or organo‐catalysts has been intensively studied by several working groups . However, few work has been done to use diols with functional pendent groups for APC preparation via polycondensation.…”

[26][27][28][29] However, few work has been done to use diols with functional pendent groups for APC preparation via polycondensation.In this work, a series of light-responsive copolycarbonates was successfully synthesized via a two-step polycondensation Starting from (2,2,5-trimethyl-1,3-dioxan-5-yl)methanamine with lightresponsive 4,5-dimethoxy-2-nitrobenzyl protecting groups, a variety of lightresponsive copolycarbonates (LrPCs) are synthesized by a general two-step polycondensation using lithium acetylacetonate (LiAcac) as catalyst. UV/Vis, 1 H nuclear magnetic resonance (NMR), and size exclusion chromatography (SEC) confirm the rapid decomposition of these polymers in response to irradiation with UV light.…”

Fully Printed Light‐Emitting Electrochemical Cells Utilizing Biocompatible Materials

“…In this work, we present the use of a nonhalogenated biodegradable solid polymer electrolyte based on poly(ε‐caprolactone‐ co ‐trimethylene carbonate) (PCL‐ co ‐TMC) and tetrabutylammonium bis‐oxalato borate (TBABOB) in LECs. PCL‐ co ‐TMC copolymers are widely used biomaterials in the field of tissue engineering, as well as solid polymer electrolyte for battery applications . Quaternary ammonium bis‐oxalato borates have already been investigated in electric double‐layer capacitors, revealing an excellent electrochemical stability .…”
