A microporous poly(vinyl alcohol)/Starch composite polymer membrane was successfully synthesized by a biodegradation method. Effects of different poly(vinyl alcohol)/Starch compositions on the porous structures of the porous polymer membranes were further investigated in detail. The characteristic properties of PVA/ Starch composite polymer membranes were systematically studied by scanning electron microscopy (SEM), SL200B angle of contact instrument and Sturm test. The result shows the formation of 1μm-10μm microporous in the blend polymer membrane, which strongly depended on the content of starch in the blend. This method is convenient and will greatly promote the practical application of porous polymer membranes in various areas.

Abstract Synthesized wurtzite ZnO nanostructures are incorporated on the poly (vinylidenefluoride-co-hexafluoropropylene) (PVdF- co -HFP) matrix, which improves the thermal behavior of as obtained thin film nanocomposite microporous polymer membrane (nanoCMPM). The nanoCMPM shows a favorable effect on the melting temperature (T m ) 142.9°C. The nanocomposite membranes were characterized by DSC and porosity studies. The nanoCMPM was prepared as a polymer electrolyte in soaking 1.0 M LiClO 4 – DMC+EC (1: 1 v/v ratio) electrolyte solution to get as nanocomposite polymer electrolytes (nanoCMPE). The optimized nanofiller dispersed composite microporous polymer membrane was found to have a high degree of porosity (76%) and excellent film strength than 8-10wt% filler concentration. It shows the ionic conductivity in the order of 10 −3 S cm −1 at room temperature. It has been further evidence from the effect on lithium salt concentration studies. The optimized membrane electrolyte has good compatibility and charge discharge character at 0.5C rate. It has the evidence applicable to perform in lithium ion polymer batteries.

Composition Ratios

Solid polymer electrolyte (SPE) membranes with varying composition ratios were prepared from poly(vinyl alcohol) (PVA), poly(acrylic acid) (PAA) and poly(metacrylic acid) (PMMA). The acrylic acid monomer with cross-linker was first blended with PVA polymer. A free radical polymerization was then carried out to form an alkaline polymer electrolyte. The solution casting method was used to form the solid polymer membranes. The solid polymer membranes were characterized by FT-IR spectroscopy, SEM morphology analysis and electrochemical impedance spectroscopy. The results showed that at room temperature the highest ionic conductivity for the PVA/PAA/KOH solid polymer membrane electrolyte system was 4.54·10-8Ω-1cm-1. The PVA/PAA polymer membrane had good mechanical strength and ductility and would be a suitable polymer membrane electrolyte for the alkaline batteries and other electrochemical systems.

Preparation and performance of poly(acrylonitrile-methylmethacrylate) based microporous gel electrolyte for Li-ion batteries were studied. The poly(acrylonitrile-methyl methacrylate (P(AMMA)) was synthesized by suspension polymerization, and poly(acrylonitrile-methyl methacrylate) microporous polymer membrane with 0.03~0.1mm was prepared by phase inversion technique. The gel electrolyte was obtained by putting the P(AMMA) microporous polymer membrane in a liquid electrolyte, which was a solution of 1.0 M LiPF6 dissolved in a 1:1 (v/v) mixture of ethylene carbonate (EC) and diethylene carbonate (DEC, and heated at 60°C for 2 hours. The microporous gel electrolyte gelled with 325 wt.% of liquid electrolyte vs. the dried membrane presented an ionic conductivity of 7.52 × 10-4 S/cm at 25°C. The coin test battery with the microporous gel electrolyte showed a good cycling performance. The discharge capacity retention was above 88% at 0.1C rate at the 50th cycle.
