“…PVC is preferred to blend with PEMA because of its better miscibility and compatibility in low or high molecular weight thereby providing good mechanical strength owing to lone pair of electron in chlorine atom which in turn strengthens the polymer backbone [9]. PVC is a cost effective polymer with high degree of versatility and processing possibilities when compared to other plastics [10]. The purpose of employing PVC as a polymer electrolyte matrix stems from the feasibility of formation of uniform hybrid films with the molecular dispersion of salt and plasticizers [5].…”

Effective influences of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide (EMIMTFSI) ionic liquid on the ion transport properties of micro-porous zinc-ion conducting poly (vinyl chloride) /poly (ethyl methacrylate) blend-based polymer electrolytes

A series of new gel polymer electrolytes (GPEs) based on different concentrations of a hydrophobic ionic liquid (IL) 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide (EMIMTFSI) entrapped in an optimized typical composition of polymer blend-salt matrix [poly(vinyl chloride) (PVC) (30 wt%) / poly(ethyl methacrylate) (PEMA) (70 wt%) : 30 wt% zinc triflate Zn(CF 3 SO 3 ) 2 ] has been prepared using facile solution casting technique. The AC impedance analysis has revealed the occurrence of the maximum ionic conductivity of 1.10 × 10 −4 Scm −1 at room temperature (301 K) exhibited by the PVC/PEMA-Zn(OTf) 2 system containing 80 wt% ionic liquid. The addition of EMIMTFSI into the optimized PVC/ PEMA-Zn(OTf) 2 system in different weight percentages enhances the number of free zinc ions thereby leading to enrichment of ionic conductivity. The structural and complexation behaviour of the as prepared polymer gel electrolytes was substantiated by subjecting these electrolyte films to X-ray diffraction (XRD) and Attenuated total reflectance -Fourier transformed infrared (ATR-FTIR) investigations. The wider electrochemical stability window~3.23 V and a reasonable cationic transference number (t Zn 2+ ) of 0.63 have been attained for the polymer gel electrolyte film containing higher loading of (80 wt%) ionic liquid. The development of the amorphous phase of these gel polymer electrolyte membranes with increasing ionic liquid content was observed from scanning electron microscopic (SEM) analysis. The results of the current work divulge the assurance of developing GPEs based on ionic liquids for prospective application in zinc battery systems.

“…A general improvement of the flexibility of the PVCs was noted, accordingly having a storage modulus far below that of pure PVC (e.g., 12–13 MPa at 40 °C vs. 377 MPa at 40 °C, respectively) [46]. However, comparing the use DEHF/DEHT mixtures of plasticizers (PVC2-5) with the single use of DEHT (PVC1), E′ and E″ were higher in the former case, most probably due to the incorporation of the stiff furan plasticizer (Table S2 and Figure S5), but the plasticizing effect was not jeopardized.…”

Replacing Di(2-ethylhexyl) Terephthalate by Di(2-ethylhexyl) 2,5-Furandicarboxylate for PVC Plasticization: Synthesis, Materials Preparation and Characterization

The worldwide regulatory demand for the elimination of non-phthalate compounds for poly(vinyl chloride) (PVC) plasticization has intensified the search for alternatives. Concomitantly, sustainability concerns have highlighted sugar-based 2,5-furandicarboxylic acid as one key renewable-chemical for the development of several products, namely di(2-ethylhexyl) 2,5-furandicarboxylate (DEHF) plasticizer. This study addresses the use of DEHF under a realistic scenario of the co-existence of both DEHF and entirely fossil-based plasticizers. More precisely, original PVC blends using mixtures of non-toxic DEHF and di(2-ethylhexyl) terephthalate ester (DEHT) were designed. The detailed structural, thermal, and mechanical characterization of these materials showed that they all have a set of interesting properties that are compatible with those of commercial DEHT, namely a low glass transition (19.2–23.8 °C) and enhanced elongation at break (up to 330%). Importantly, migration tests under different daily situations, such as for example exudation from food/beverages packages and medical blood bags, reveal very low weight loss percentages. For example, in both distilled water and phosphate buffered saline (PBS) solution, weight loss does not exceed ca. 0.3% and 0.2%, respectively. Viability tests show, for the first time, that up to 500 μM of DEHF, a promising cytotoxic profile is observed, as well as for DEHT. Overall, this study demonstrates that the combination of DEHF and DEHT plasticizers result in a noticeable plasticized PVC with an increased green content with promising cytotoxic results.

“…In this work conductivity studies of PEMA/ENR-50 blend of fixed weight ratio of 70:30 added with LiCF 3 SO 3 is reported . Blend electrolytes based on PEMA that have been reported in the literature includes PEMA-PVC [2,3,4], PEMA-(PVdF-HFP) [5,6], PEMA-PVdF [7] and PEMA-PMMA [8] amongst others. However reports on lithium conducting polymer electrolytes based on blends of PEMA and ENR50 is lacking.…”

Solid polymer electrolytes (SPEs) comprising of a blend of Poly (ethyl methacrylate) (PEMA) and Epoxidized natural rubber-50 (ENR50) as polymer host and lithium triflate (LiCF3SO3) as dopant were prepared by solution cast technique. The blend based polymer electrolytes have a fixed PEMA/ENR50 ratio of 70:30 by wt. % as at this ratio ENR-50 imparted stable mechanical properties to the otherwise fragile PEMA. The incorporation of LiCF3SO3into the blend is found to increase the conductivity of PEMA/ENR50. The highest conductivity achieved was 3.64 x 10-5Scm-1at 40wt. % LiCF3SO3. The structure of the samples was investigated by X-ray diffraction and the results show that the highest conducting sample is the most amorphous.
