Poly(vinylidene fluoride), PVDF, and its copolymers exhibit interesting properties for use as separator membranes in lithium-ion battery applications. This review presents the developments summarizes main characteristics of these materials membranes. The is divided into three categories regarding composition polymer membranes: single polymers, composites blends. For each category, ion transport behaviour presented. Finally, guidelines further investigations are outlined.
Poly(vinylidene fluoride), PVDF, based nanocomposites with different clay structures have been processed by solvent casting and melt crystallization. Depending on the melting temperature of polymer, nanocomposite recrystalises in electroactive γ or nonelectroactive α phase polymer. This fact is related to thermal behavior clay. For montmorillonite clay, full crystallization occurs for contents lower than 0.5 wt %, allowing maintain mechanical properties polymer matrix. The electroactivity...
Abstract Ionic liquids (ILs) have emerged as a novel class of chemical compounds for the development advanced (multi)functional materials with outstanding potential in applications several areas due to their unique properties and functionalities. The combination ILs polymers, composite, allows developing smart materials, which synergistically combine features specific polymers ILs. Moreover, can be extensively modified by incorporation functional groups into cation, anion, or both. Thus, it...
Flexible multiferroic 0–3 composite films, comprising NiFe2O4 and CoFe2O4 ferrite nanoparticles in a polyvinylidene fluoride (PVDF) matrix, have been prepared by solvent casting melt crystallization to investigate the polymer β-phase nucleation mechanism. Infrared spectroscopy confirms of polymeric electroactive with addition both ferrites, although loading needed obtain highest amount was found be one order magnitude higher NiFe2O4/PVDF nanocomposites. Transmission electron microscopy...
Abstract Biobased resources are proposed as next‐generation materials for advanced application. Among them, silk fibroin, a protein‐based material generally obtained from Bombyx mori cocoons, is considered to play an increasing role in the development of more sustainable generation devices. In this review, fibroin molecular structure and its original properties presented, together with wide overview available modifications processing methods reach custom structural functional variations.
Abstract For the proper design and evaluation of next‐generation lithium‐ion batteries, different physical‐chemical scales have to be considered. Taking into account electrochemical principles methods that govern processes occurring in battery, present review describes main theoretical thermal models allow simulation performance including materials components (electrodes separators) battery geometries. As separator plays an essential role safety recent work for this component are shown, with...
Poly(vinylidene fluoride), PVDF, thin films have been processed by spin-coating with controlled thickness, morphology and crystalline phases. The influence of the polymer/solvent mass ratio solution, rotational speed spin-coater temperature crystallization on properties material has investigated. It is shown that high-quality thicknesses from 300 nm to 4.5 µm a amount electroactive phases can be obtained in single deposition step, which allows tailoring characteristics for specific applications.
Biodegradable poly(L-lactic acid) (PLLA) microfibers were prepared by electrospinning varying the applied potential, solution flow rate and collector conditions. PLLA fibers with smoothly oriented random morphologies obtained characterized scanning electron microscopy. The optimum fiber orientation was at 1000 rpm using a 20.3 cm diameter collecting drum, while for higher lower drum rotation speeds, rapid motion of jets resulted in distribution. deformation jet solidification during often...
