“…When the SM‐MMT content was increased to 10%, the d ‐spacing decreased from 2.1 to 1.9 nm. The XRD results also indicated that the Tween 80 surfactant significantly affected the dispersion of SM‐MMT because of the adsorption on the surface of the particles and intercalation between the silicate layers of SM‐MMT …”

International audienceIn this work, an extensive study was carried out on the preparation and characterization of nanoclay biocomposites based on cellulose to substitute for synthetic polymer foam trays as food-packaging materials. The preparation stage was performed via a dissolution/regeneration route followed by drying with lyophilization. The chemical, physical, mechanical, and morphological properties of the prepared composite foams were characterized by several methods, including scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, mechanical tests, density, and color analyses. The obtained results indicate that the presence of nanoclay in the cellulose matrix caused more uniformity in the structure of the foams. Also, an increase in the nanoclay content resulted in a higher density, compressive strength, and Young's modulus. The achievements from this study suggest that the prepared cellulose nanocomposite foam could be a potential alternative to commercial synthetic foams for packing food products

“…The initial thermal decomposition of (Nascimento et al, 2012). Furthermore, in the third stage, polyethylene begins to degrade at a temperature of 400°C, producing gas and hydrocarbon oil (Abdullah et al, 2013). The curve of TGA shows that degradation of TPSS /LLDPE compatibilized blends does not show a significant reduction in each phase.…”

“…Meanwhile, the decrease of seawater sampling weight from 56 to 18% at a concentrated LLDPE of 10-30%, as well as the decreased percentage of soil buried sampling achieved 50% at a concentrated LLDPE of 30%, with the decomposition of 17% at the 30 th Days. The more concentration of LLDPE contained in bioplastic, the smaller percentage of degradation rate (Abdullah et al, 2013). Table 2 contains specific data.…”

The purpose of this study was to improve the mechanical and physical properties, degradation performance, and water absorption of a thermoplastic mixture of sago starch with the addition of Linear Low-Density Polyethylene (LLDPE). The method used is the grafting method where polyethylene is grafted onto Maleic Anhydride (LLDPE-g-MA). In this research, Thermoplastics Sago Starch (TPSS) was made with a mixture of Sago Starch (65%) and Glycerol (35%), added with water as a solution. Compatibilizer (PE-g-MA) was made by reacting LLDPE (88%) and Maleate Anhydride (9%) with an additional initiator of Benzoyl Peroxide (3%). The concentration of LLDPE varied from 10,15, 20, 25, and 30%. Substances were mixed into an internal mixer Thermo Haake Polydrive with a speed of 100 mm/minute, for 15 minutes. The concentration of 30% LLDPE produced the highest tensile strength and elongation at a break of 4.30 N/mm2 and 2.15%, respectively. Simultaneously, as LLDPE concentration increased, Young's Modulus decreased. This was powered by the morphology of the sampling surface, with the occurred reaction of adhesion interface or dispersion of LLDPE toward the whole surface with the assistance of compatibilizer as connecting substance between hydrophilic polymer and a hydrophobic polymer, which could improve the properties of mechanical. The formation of ester groups from the reaction of inter groups of hydroxyls derived from the starch with the groups of anhydride derived from the mixture of compatibilizer was visibly seen at the peak of 1693 cm -1 . The degradation performance of the TPSS: LLDPE mixture with a ratio of 70:30 showed good performance where the degradation continued to increase up to 42% on the 30th day of degradation in freshwater, 18% in seawater, and 17% in soil burial. While the water absorption test showed that the higher concentration of LLDPE, the lower speed of water absorption.

“…This thermal analysis includes thermogravimetry analysis (TGA), derivate thermogravimetry (DTG), and differential thermal analysis (DTA). And differential scanning calorimetry (DSC) (Abdullah et al, 2014). 2), at the beginning of the mass degradation at T1% and T5%, there was no significant difference between neat LLDPE and LC blends.…”

In this paper, we report that the compatibility of polymer blends between linear lowdensity polyethylene (LLDPE) and cyclic natural rubber (CNR) can be increased by the addition of oleic acid-grafted linear low-density polyethylene. The research aims to investigate the effect of LLDPE-g-OA compatibilizer in LLDPE/CNR blends on improving the mechanical properties and characteristics of the blends. The LLDPE/CNR/LLDPE-g-OA blends (compatible blends) were prepared by blending methods in the molten phase using an internal mixer set at a temperature of 160 o C with a rotation speed of 100 rpm. The LLDPE pellets were inserted into it until melts and followed with an addition of CNR and LLDPE-g-OA. The tensile strength test results have shown an increase in mechanical properties after the addition of the compatibilizer with a maximum content of 4 wt%. The difference in FTIR spectra of compatible blends is indicated by the presence of C=C bonds from CNR, which appear at 1654.9 cm -1 , indicating the occurrence of physical bonds in the blends. The existence of the LLDPE-g-OA compatibilizer has increased the thermal stability of the polymer blends and changes in the melting point temperature of 124 0 C. Compatible blends showed that the surface morphology was smoother, and there were significant microstructural changes compared to incompatible blends.
