Graphite was purchased from Sigma-Aldrich. The graphene electrodes were printed using a commercially available office inkjet printer (Canon Pixima Ip1300). The polyethylene terephthalate (PET) film, polyvinylidene fluoride (PVDF) pellets (with a molecular weight of 275,000, determined via gel permeation chromatography), zinc acetate dihydrate, zinc nitrate hexahydrate, hexamethylenetertramine and ethanol were obtained from Sigma−Aldrich. PVDF film was obtained from the Fils Corporation (South Korea).
Polyvinylidene fluoride pvdf pellets
Manufactured by Merck Group
Sourced in Germany
Polyvinylidene fluoride (PVDF) pellets are a type of thermoplastic polymer material. They exhibit high chemical resistance, thermal stability, and excellent mechanical properties. PVDF pellets are commonly used as a raw material in the manufacturing of various industrial and laboratory equipment.

Polyvinylidene fluoride (PVDF) pellets (MW = 84,000 Da) were procured from Sigma-Aldrich, and high purity acetone, N,N′-dimethylacetamide (DMAC) and N,N′-dimethylformamide (DMF) were purchased from Merck. Prior to the electrospinning process, different polymeric solutions at 10, 20, 25 and 30 (w/v%) PVDF concentrations were prepared by dissolving PVDF pellets in DMAC/acetone mixture of solvents in equal ratio to obtain neat polymeric PVDF solutions. Then, the mixtures were stirred further under constant and continuous magnetic stirring for approximately 2 h at 70 °C separately, without adding any catalyst, to allow PVDF dissolve completely and the optimum viscosity was obtained for the electrospinning process.

For the experiments we used deionized water (DIW, Merck Milli-Q direct, resistivity > 18.2 MΩ cm). We obtained 1-Methyl-2-pyrrolidinone (NMP), Poly(methyl methacrylate) (PMMA) powder and poly(vinylidene fluoride) (PVDF) pellets from Sigma Aldrich. We obtained acetone from Thommen-Furler AG and hydrophobic fumed silica nanoparticles (HFS, Aerosil R8200) from Evonik. We used sheets of PMMA in thickness of 175 µm and 1 mm obtained from Schlösser GmbH and transparent float glass microscope slides in thickness of 1 mm from VWR (cut edge, ECN 631-1550). We purchased bare wire fine gage T-type thermocouples from Omega: COCO-001 with wire diameter of 0.025 mm and COCO-003 with wire diameter of 0.075 mm.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
