New fluoroboronated materials were synthesized by modifying poly-(vinylidene fluoride-co-2-(trifluoromethyl) acrylic acid) copolymers. These novel fluoropolymers exhibit enhanced thermal stability and potential applications in electronics and coatings.
Area of Science:
- Polymer Chemistry
- Materials Science
Background:
- Vinylidene fluoride (VDF) and 2-(trifluoromethyl) acrylic acid (MAF) were copolymerized to create poly-(VDF-co-MAF).
- MAF, while not homopolymerizing, acts as a suitable comonomer for VDF radical copolymerization.
Purpose of the Study:
- To synthesize novel fluoroboronated materials via chemical modification of poly-(VDF-co-MAF) copolymers.
- To investigate the properties and potential applications of these new materials.
Main Methods:
- Radical copolymerization of VDF and MAF in different solvents (DMC or 1,1-difluoro-1-chloroethane).
- Condensation of the resulting copolymers with aminophenyl boronic acid pinacol ester (APBAPE).
- Characterization using NMR (1H, 11B, 13C, 19F) and ATR IR spectroscopy, and thermal analysis.
Main Results:
- Two poly-(VDF-co-MAF) copolymers were synthesized with varying molar masses and transfer rates depending on the solvent.
- Successful addition of APBAPE to the fluorinated copolymer was confirmed by spectroscopic analysis.
- The novel poly-(VDF-co-MAF.APBAPE) copolymers demonstrated improved thermal stability compared to their precursors.
Conclusions:
- Novel fluoroboronated copolymer materials were successfully synthesized.
- The incorporation of boron-containing groups enhances the thermal stability of the fluoropolymers.
- These materials show promise for applications in areas such as electronics and coatings.
