2014年2月21日 · The effects of cetyl trimethyl ammonium bromide (CTAB) on the crystallization behavior of PVDF during isothermal crystallization and annealing process were studied, and the results showed that the polar phases (β, γ) were induced by CTAB when PVDF was isothermally crystallized at 145–160 °C.
Different Crystallization Behaviors of Poly(vinylidene fluoride ...
2023年10月11日 · Crystallization of poly(vinylidene fluoride) (PVDF) either blended with or coated with cetyltrimethylammonium bromide (CTAB) during isothermal and nonisothermal processes has been studied, which reveals the influence of the interaction way between PVDF and CTAB on the polymorphic behavior of PVDF.
十六烷基三甲基溴化铵共混或包覆聚偏二氟乙烯的不同结晶行 …
2023年10月11日 · 研究了与十六烷基三甲基溴化铵(CTAB)共混或涂覆的聚偏二氟乙烯(PVDF)在等温和非等温过程中的结晶,揭示了PVDF和CTAB之间的相互作用方式对PVDF多晶型行为的影响。 混合样品中含量有限的 CTAB 的随机分散导致 PVDF 链的三种不同状态,即完整链以及由离子偶极相互作用引起的 TGTG' 和 TTT 链序列。 完整链和TGTG'序列促进PVDF在α相结晶,而TTT链序列导致PVDF在高温下在γ相结晶,这使得后期α完全转变为γ ' 。 阶段。 另一 …
Multiple stage crystallization of gamma phase poly(vinylidene …
2014年9月2日 · Five stages are identified during the crystallization of γ phase PVDF induced by CTAB. The kinetic characteristics of α and γ phases influenced by ion-dipole interactions can be investigated separately for the first time. α phase always appears earlier, and grows faster than the γ phase in the early stage.
Ionic Surfactant-Assisted PVDF Nanofabrics with High ... - Springer
2024年7月2日 · In this study, a highly flexible non-woven fabric was developed from electrospun PVDF nanofibers containing cationic and anionic surfactants. Cetrimonium bromide (CTAB) was used as a cationic surfactant, while sodium lauryl sulfate (SLS) was used as an anionic surfactant.
PVDF-Based Dielectric Composites with High Energy Density by …
2024年9月10日 · The results show that CTAB@Sep nanofibers can serve as efficient nucleation agents for γ-PVDF crystals. Furthermore, Sep nanofibers modified with CTAB can significantly promote the dispersion of C-MWCNTs through the electrostatic adsorption effect and then block the conductive path, therefore improving the dielectric and energy storage ...
In our present work, to develop the photovoltaic energy storage device (PESD) initially, we have synthesized the cetrimonium bromide (CTAB)/PVDF composite thin film via simple solution casting...
