“…This confirmed the complete elimination of PVB from blended fiber by ethanol treatment. Other typical bands at 1377 cm −1 (distinguishing band for polyolefin [45]), 1463 cm −1 , and 2915 cm −1 ascribed to -CH 3 symmetric deformation vibrations, bending deformation, and -CH 2 asymmetric [46], respectively, are firmly visible for pure LDPE and PVB-removed LDPE fiber. This supported the notion that the characteristics of PVB-removed LDPE and pure LDPE fiber are similar.…”

We prepared low-density polyethylene (LDPE) nanofiber, a few hundred nanometers in diameter, using polyvinyl butyral (PVB) and a laser melt-electrospinning (M-ESP) device. We blended PVB with LDPE via an internal melt mixer, removed the PVB after M-ESP by ethanol treatment, and studied the influence of PVB on fiber diameter. A substantial diameter reduction with improved crystallinity of LDPE fiber was observed with increased PVB content in the blend. PVB inclusion also increased the polarity of the LDPE/PVB blend, resulting in better spinnability. The removal of PVB from LDPE/PVB blend fiber caused a massive drop in the LDPE fiber diameter, due to fiber splitting, particularly in PVB-rich samples. Fourier transform infrared (FTIR) spectroscopy of fibers confirmed that the prepared nanofiber was the same as pure LDPE fiber.

“…Before the biodegradation of LDPE, FTIR spectra shows a characteristic peak at 2912.75, 2844.02, 1461.93, 1377.41 were associated with –CH 2 asymmetric, –CH 2 symmetric, bending deformation, and –CH 3 symmetric deformation vibration, respectively. The frequencies seen at 729 and 719 cm −1 were associated to the deformation vibrations 40 . As compared to their correspondence control, significant changes were observed in the range of FTIR spectra of the plastic sheet after degradation.…”

The focus of the present research is on the biodegradation of low density polyethylene (LDPE):polylactic acid (PLA) and LDPE:PLA:organo modified montmorillonite (OMMT) polymer nanocomposites. PLA was synthesized using the polycondensation method. The surface modification of nanomaterials is affected by various factors such as modifying agent, dispersion medium, and the dispersion of nanoparticles. Ultrasound cavitation technique improves the better dispersion of MMT in reaction mixture and enhances the interaction rate of a modifying agent with clay layered structure. A mixture of aminopropyltriethoxysilane and octadecyl amine was used for the surface modification of MMT. Polymer nanocomposite was prepared using the melt mixing method and used further for the biodegradation study. The mesophilic bacterium isolated from the dumping yard, identified by the 16rRNA technique, was capable of biodegradation of LDPE:PLA and LDPE:PLA:OMMT polymer nanocomposites. Isolated bacterial AP1 is 96.05% identical to the current MCCC1A02146 strain of Bacillus albus. After 50 days of incubation, the polymer nanocomposite sheet was characterized using Fourier transform infrared, X‐ray powder diffractometer, UV–Visible spectroscopy, Field Emission Scanning Electron Microscope (FESEM), etc. Further, LDPE:PLA30% (17.5%) and LDPE:PLA30%:OMMT4.5phr (19.20%), shows maximum percentage degradation. It has been observed that the addition of OMMT contributes to an enhancement in the polymer nanocomposite degradation because it has a large d‐spacing gap that is (21 Å) that enables the water to penetrate in the polymer matrix and increases the growth of bacteria within the polymer matrix. The highest change in biomass and change in extracellular protein content was found to be (39.11 mg/L and OD 0.38) LDPE:PLA30%:OMMT4.5phr composites. In addition, the mechanical properties decrease effectively after the incubation period, for LDPE:PLA 30% and LDPE:PLA30%:OMMT4.5phr.

“…In the spectra of pure LDPE, the two split peaks at 2916 and 2849 cm −1 are assigned to the asymmetric and symmetric stretching vibration bands of -CH 2 -; the peaks at 1465 and 721 cm −1 correspond to the deformation vibration band and in-plane rocking vibration band of -CH 2 -, respectively [ 39 ]. In contrast, the direct crystallization of LDPE on the long axis of CNTs (LDPE-CNTs) indicates a small shift of the asymmetric and symmetric stretching vibration band (-CH 2 -) from 2916 and 2849 cm −1 in PE to 2922 and 2852 cm −1 , respectively, in the CNT-LDPE nanohybrid structure.…”

Morphological and Chemical Analysis of Low-Density Polyethylene Crystallized on Carbon and Clay Nanofillers

Interest in carbon and clay-based nanofillers has grown in recent years. The crystallization behavior of low-density polyethylene (LDPE) was studied using a variety of notable nanofillers used in engineering applications and prepared using a solution crystallization method. Carbon nanotubes (CNTs), graphene oxide nano-platelets, clay (montmorillonite), and modified clay (surface-modified with trimethyl stearyl ammonium) were used to induce heterogeneous crystallization of LDPE. The crystallized LDPE samples, imaged using scanning and transmission electron microscopy, revealed different microstructures for each nanohybrid system, indicating these various nanofillers induce LDPE lamellae ordering. The underlying interactions between polymer and nanofiller were investigated using FTIR spectroscopy. X-ray diffraction (XRD) was used to determine crystallinity. This work examines how the differences in morphology and chemical structure of the nanofillers induce changes in the nucleation and growth of polymer crystals. These results will provide guidance on functional design of nano-devices with controlled properties.
