“…Nanofiber samples fabricated at different voltages are heated to 80, 105, 150, and 200°C for 30 min in an oven (13‐247‐725G, Thermo Fisher Scientific Inc., USA) and then cooled to the room temperature (23°C ± 1°C). The selection of the heating temperatures is based on the thermal properties of the PMMA 36,37 : 80°C is the drying temperature of the as‐spun nanofibers; 105°C is the glass transition temperature ( T g ) of PMMA; 150°C is the melting point of PMMA; and 200°C is the upper limit of the PMMA/PDMS membrane heat temperature because the PMMA/PDMS membrane samples solidified and partially turned into powders when the heat temperature exceeds 200°C according to our preliminary tests. The PMMA/PDMS nanofibrous membrane samples after heat treatment are used for further characterizations.…”

This paper studies the effects of five parameters, including fiber diameter, crystallinity, thickness, packing density, and surface roughness, on the transparency of electrospun polymethyl methacrylate/polydimethylsiloxane (PMMA/PDMS) nanofibrous membranes after heat treatment. The PMMA/PDMS membranes produced at an electrospinning voltage of 20 kV reaches 54.85% transparency with the diameter 0.759 μm, crystallinity 14.81%, thickness 9.2 μm, roughness 0.659 μm, and packing density α 0.0081% after the heat treatment from 80 to 200°C. In general, the PMMA/PDMS membranes present higher transparency with the decrease of diameter, crystallinity, thickness, roughness, and packing density. The influencing parameters on transparency are first quantified by multiple nonlinear regressions with a R2 of the model equals 0.869. A composite scaled sensitivity (CSSj) analysis shows that the most influential factor is the nanofibrous membrane thickness with a CSSj value of 1, followed by fiber diameter with a CSSj value of 0.515. The CSSj values for packing density, membrane roughness and crystallinity are 0.385, 0.361, and 0.173, respectively. Finally, the nanofibrous membrane transparency is a function of nanofiber material density, fiber diameter, and nanofibrous membrane thickness based on the Chandrasekhar radiative transfer equation and the Rayleigh's Scattering Theory.

“…The materials were dried in the vacuum oven with 50 ℃ for 3 to 4 hours to remove moisture. Based on our previous work [41], the percentage ratio of 80:20 of PMMA-PLA was employed in the present system as a host polymer. The tetraethylene glycol dimethyl ether (TEGDME) obtained from Acros Organics was immersed with a molecular sieve (4Å, Sigma Aldrich) prior to preparing hybrid gel polymer electrolytes.…”

“…To better understand the interaction between PMMA-PLA hybrid polymer and LiTFSI, Figure 1 depicts FTIR spectra for PMMA-PLA, raw LiTFSI and PMMA-PLA-LiTFSI hybrid gel polymer electrolytes. It reveals that the IR spectrum of PMMA-PLA hybrid polymer shows a peak at 2872 cm -1 which is assigned to C-H stretching, COOC stretching at 1728 cm -1 , O-CH 3 stretching at 1451 cm -1 , CH 3 stretching at 1350 cm -1 , and C-O-C stretching at 1100 cm -1 [41].

“…Figure 4 illustrated the proposed mechanism diagram to explain the interaction that occurred in the hybrid polymer complexes. Prior to Lithium salt, PMMA interacts with PLA through dipole-dipole forces between oxygen atoms from PMMA and carbon atoms from PLA [41]. When LiTFSI was incorporated into the system, they will be separated into Li + cations and TFSI-anions.…”

In this work, the investigation on hybrid gel polymer electrolytes (HGPEs) comprising polymethyl methacrylate (PMMA)-polylactic acid (PLA) incorporate with LiTFSI were carried out. The HGPEs samples were characterized for their structural, thermal and ionic conduction properties via FTIR, XRD, DSC, and EIS. FTIR analysis show the indication of the interaction between PMMA-PLA hybrid polymer and LiTFSI with the appearance of peak and changes in peak shifting at the coordinating site from polymer blend. The DSC analysis shows that the glass transition temperature (Tg) of HGPEs was decreased as the LiTFSI content increases, suggesting that the HGPEs system has good thermal stability. The ionic conductivity was calculated based on the Cole-Cole plot and the incorporation of LiTFSI with 20 wt. % into hybrid polymer matrixes revealed the maximum ionic conductivity of 1.02 х 10-3 S cm-1 at room temperature as the amorphous phase increases. The dissociation of ions and transport properties of the PMMA-PLA-LiTFSI systems was determined via dielectric response approach and it was found that number density (ɳ), mobility (μ), and diffusion coefficient (D) of mobile ions follows ionic conductivity trend.

“…Despite the upsides of good mechanical properties, ease of processing, thermoplasticity, biocompatibility, biodegradation, ductility, and crystallization, polylactic acid (PLA) also has negative attributes that constrain its application and development. These include characteristics such as brittleness, low ductility, and low‐crystallization rate 8–11 . In response, polymer processing techniques are developed to modify PLA.…”

Polylactic acid (PLA) possesses many advantages, especially biodegradability, and has subsequently been used in many regions. Unfortunately, its disadvantages, including its brittleness, become an obstacle to its application and constrain its development. In this study, Polystyrene‐b‐poly(ethylene‐co‐1‐butene)‐b‐polystyrene (SEBS) is used as the toughener and maleic anhydride grafted polypropylene (PP‐g‐MA) is used as the compatibilizer. The melt‐blending technique for polymers is employed to modify PLA in order to produce PLA/SEBS membranes. For PLA/SEBS membranes, the optimal matrices are made of a blending ratio of PLA/SEBS/PP‐g‐MA being 57/40/3. Next, polyhexamethylene guanidine hydrochloride (PHGH) is combined with the optimal membranes to form PLA/SEBS antibacterial membranes, the crystallinity, thermal properties, and antibacterial properties of which are examined to determine the effect of the PHGH content. The test results show that an appropriate content of SEBS or PHGH has a positive influence on PLA/SEBS antibacterial membranes. Moreover, the antibacterial membranes exhibit greater antibacterial efficacy against Escherichia coli (E. coli) than is gained with an increase in the PHGH content.
