“…The thermal shrinkage ratio for the bare PE membrane was 83.3% after storage at 140 C for 30 min, while that for polyimide-coated PE membranes decreased markedly to 10%. Another approach is using a nonwoven separator such as polyethylene terephthalate (PET) [11,12], poly(phthalazinone ether sulfone ketone) (PPESK) [13], polyimide (PI) [14,15], and thermally rearranged polybenzoxazole (TR-PBO) [16e26] membranes by an electrospinning method to develop thermally stable separators. Among these, thermally rearranged polybenzoxazoles (TR-PBOs) have proved to be promising materials for gas separation membranes due to their inherent ultra-pores, which induce both extraordinary permeability and selectivity [16e26].…”

“…However, plastic bottles as drink packaging are composed of PET); therefore, waste plastic bottles can potentially be used as a membrane material 8 . This new source of polymeric material helps to reduce the waste of plastic bottles and constitutes a green alternative to limit the consumption of polymers.…”

The aim of the present study was to evaluate the possibility of Background: using recycled polymer (waste polyethylene terephthalate [PET] bottles) as a membrane material. Furthermore, the effect of the addition of a pore-forming agent and preparation conditions was also observed.Porous Methods: polymeric membranes were prepared via thermally induced phase separation by dissolving recycled PET in phenol. PET polymer was obtained from waste plastic bottles as a new source of polymeric material. For original PET membrane, the casting solution was prepared by dissolving of 20wt% PET in phenol solution. For PET modified membrane, a 5 wt% of polyvinylpyrrolidone (PVP) was added into polymer solution. The solution was cast onto a glass plate at room temperature followed by evaporation before the solidification process. The membranes formed were characterized in terms of morphology, chemical group, and filtration performance. A humic acid solution was used to identify the permeability and the solute rejection of the membranes. Results:The results showed that the recycled PET from waste plastic bottles was applicable to use as a membrane material for a water treatment process. The highest rejection of humic acid in a water sample, which reached up to 75.92%, was obtained using the PET/PVP membrane.The recycled PET Conclusions: from waste bottles was successfully used to prepare porous membrane. The membrane was modified by the addition of PVP as a membrane modifying agent. SEM analysis confirmed that the original PET membrane has a rough and large pore structure. The addition of PVP improved the pore density with a narrow pore structure. The PET/PVP membrane conditioned with evaporation was the best in humic acid rejection.

“…Moreover, PIs exhibit good affinity with GPEs that contain plasticizing organic solvents like carbonate compounds. Hence, carbonate compound containing solvents can be immensely combined within the polymer matrix in network which can largely improve the electrolyte retention of PI‐based electrolytes …”

In this study, a novel ion conductive polyimide (PI) nanofiber reinforced photocured hybrid electrolyte has been fabricated. Polyimide fibers were fabricated with the reaction between 4,4′‐oxydianiline (ODA) and 3,3′,4,4′‐benzophenonetetracarboxylic dianhydride (BTDA) followed by electrospinning and thermal imidization methods. Then, PI electrospun fibers were dipped into hybrid resin formulation containing bisphenol A ethoxylate dimethacrylate (BEMA), poly (ethylene glycol) methyl ether methacrylate (PEGMA) and 3‐(methacryloyloxy) propyltrimethoxysilane (MEMO) and then photocured to prepare PI nanofiber reinforced electrolyte membrane. Photocured membranes were soaked into lithium hexafluorophosphate (LiPF6) before measuring electrochemical stability and ionic conductivity of hybrid polyelectrolyte. The chemical structure and electrochemical performance of the electrolytes were examined by Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV) and scanning electron microscopy (SEM) analysis. The incorporation of MEMO into organic matrix effectively increased the modulus from 2.83 to 5.91 MPa. The obtained results showed that a suitable electrolyte for Li‐ion batteries with high lithium uptake ratio, high conductivity (7.2 × 10−3 S cm−1) at ambient temperature and wide stability window above 5.5 V had been prepared.
