“…The F-containing PUs typically have a variety of excellent or unique properties, such as good chemical resistance, low surface tension, low refractive indices, and low dielectric constants. [5,6] These PUs can be obtained by incorporating fluoro chain extenders, [7][8][9][10] fluorinated soft segments, [11][12][13][14] or fluorinated hard segments. [15,16] For example, Tan et al prepared a unique chain extender [i.e., 3-(2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluoro-octyloxy) propane-1,2-diol (PFOPDOL)] that was used to synthesize a specific PU polymer.…”

*In this study, biodegradable fluorine-containing polyurethanes (PU/OFHD) were synthesized using 4,4'-diphenylmethane diisocyanate, polycaprolactone diol (PCL), and 2, 2,3,3,4,4,5,5,. PCL is a biodegradable soft segment, and OFHD is a fluoro chain extender. In addition, other polyurethanes (PU/HD) were synthesized using 4,4'-diphenylmethane diisocyanate, PCL, and another chain extender [i.e., 1,6-hexanediol (HD)] for comparison.Gel permeation chromatography analysis indicated that the molecular weight of PU/OFHD is greater than that of PU/HD.19 F nuclear magnetic resonance analysis revealed that the OFHD chain extender was successfully incorporated into the backbone of PU. According to Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy analyses, strong interactions between the C=O and CF 2 groups in PU/OFHD exist. Based on thermal analysis, PU/OFHD exhibited an initial decomposition temperature that was 6.5-7.9°C higher than that of PU/HD. Differential scanning calorimetry and dynamic mechanical analysis analyses indicated that both the glass transition (Tg) and dynamic Tg of PU/OFHD are higher than those of PU/HD. Mechanical property analysis demonstrated that the tensile strength of PU/OFHD is higher than that of PU/HD. Moreover, PU/OFHD exhibited better chemical resistance than PU/HD. The scanning electron microscope images indicated that both PU/HD and PU/OFHD exhibited higher hydrolytic degradation at a higher PCL content. However, PU/OFHD is less degradable than PU/HD.

Solid polymer electrolyte (SPEs) has drawn great attention nowadays, particularly in the field of science and applied science, specifically, those used as separators in industries and researchers for the assemblage of some "classified batteries" and super capacitors. In this report, we present the grandeur of this SPE (pure type), particularly at room temperature, such that, it can be applied as an electrolyte as well as a separator in supercapacitor fabrication. The SPEs were produced from the composition of polyvinyl alcohol (PVA) and Phosphoric acid (H 3 PO 4 ), such that, the PVA samples were kept constant while the phosphoric acid was varied at 0, 10, 20, 30, 40, 50, 60, and 70 wt. %. After the experimentation, the pure polymers show excellent results in term conductivity, in that, it has recorded a conductivity as high as 2.56 x 10 -3 Scm -1 at the compositions of 70 wt. %. Aside that, we also observed that, the bulk moduli (R b ) value decreases with the increase in concentration, with pure solid polymer electrolyte (PSPE) recording 2.5 Ω at the highest composition of 70 wt. %.

The nobility of solid polymer electrolyte (SPEs) has made them a subject of interest, especially in the arena of science and technology, and most importantly as they are used as separators in industries and by researchers for the assembly of some "few battery types" and supercapacitors. This paper, highlights the nobility of the hybrid solid polymer electrolyte (HSPE), particularly at room temperature such that, it can be used as an electrolyte as well as a separator in supercapacitor fabrication. The hybrid SPEs were produced from the composition of polyvinyl alcohol (PVA) and Phosphoric acid (H 3 PO 4), where the PVA samples were kept constant while the phosphoric acid concentration was varied at 0, 10, 20, 30, 40, 50, 60, and 70 wt. %. XRD results show that, the crystallinity decreases as the acid concentration increases and consequently, there is an enhancement in the amorphicity of the samples responsible for the process of ion transport. This characteristic behavior was confirmed by the analysis of the differential scanning calorimetry results. FESEM result pictured the entangling nature of the combined samples. High conductivity of 1.67 x 10-3. Scm-1 was recorded for the HSPE at the composition of 70:30 wt. %. It was also noticed that, the bulk modulus, R b of the HSPE (5.73 Ω) at the aforementioned composition decreases with the increase in concentration. Keywords: hybrid solid polymer electrolyte (HSPE), polyvinyl alcohol (PVA), phosphoric acid (H 3 PO 4), Electrochemical Impedance Spectroscopy (EIS). Differential Scanning Calorimetry (DSC) Analysis Polymer Electrolytes (SSPE):-In SSPE, solvents, both aqueous and non-aqueous swells the host polymer live PVA. So, the dopant ionic solutes such as H 3 PO 4 is hosted in the swollen lattice thereby permitting the motion of ions in the solvent swollen region of the polymer host. Their conductivity depends on the concentration of the solvent in the region that is being swollen (Ulaganathan et al., 2012). And lastly (iii) the Solvent Free Polymer Electrolytes (SFPE): These are polymer salt complex, which is formed by complexes between salts of alkali metals and polymer containing solvating hetroatoms, example; O, S and N (Ulaganathan et al., 2012). The complexation between poly ethylene oxide (PEO) and alkali metal salts is a good example of SFPE. SFPE are sub-classified into three also. They are; (a) Solid Polymer Electrolytes (SPEs), (b) Gel Polymer Electrolytes (GPEs), and (c) Composite polymer electrolytes (CPEs) (Kuo et al., 2013; Tripath et al., 2012). GPEs can be simply regarded as plasticizers incorporated polymer-salt complex (Ulaganathan et al., 2012). They are therefore consisted of a liquid electrolytes immobilized in a polymer matrix (Hashmi, 2013a) and exhibits high ionic conductivity (10 −3 to 10 −4 Scm −1 at ambient temperature) and can be obtained by either loading of a liquid electrolyte in a microporous matrix or by increasing the viscosity of a liquid electrolyte through the addition of a soluble polymer until gel consistency www.ccsenet.org/...
