“…The increase in the uptake of water in the biocomposites is due to the presence of hydrophilic NS, which displays a higher tendency of absorption than the hydrophobic LDPE. NS possess a lot of hydroxyl groups and are readily available for hydrogen bonding with the water molecules . Thus, water molecules can quickly saturate and adsorb the surface of the biocomposites and also penetrates through the voids, resulting in higher water absorption in a short period .…”

Low density polyethylene‐g‐maleic anhydride‐g‐starch nanoparticle (LMNS) biocomposites have been synthesized in water medium. LMNS biocomposites were fabricated with different starch nanoparticle (NS) loadings (2, 4, 6, 8, and 10 wt%) by compression molding technique. Fourier transform infrared spectroscopy revealed ester linkage between maleic anhydride grafted low density polyethylene (LM) and NS, thereby confirming the improved compatibility of the biocomposites. Thermal analysis confirmed the chemical linkage of NS on LM chains. The wettability and surface roughness characteristics of biocomposites were evaluated by water sorption, static contact angle, and atomic force microscopy. Water sorption was improved due to the increase of NS content in samples, whereas the water contact angle and surface roughness were diminished. The load at maximum, tensile strength and percentage of elongation at break for the biocomposites were enhanced with the increase in NS content. The morphology analysis of samples revealed homogenous distribution and good interfacial adhesion. The biodegradation enhancement of samples has been revealed by fungal and soil burial tests. POLYM.

Effects of different filler types on decay resistance and thermal, physical, and mechanical properties of recycled high-density polyethylene composites

“…The poor interfacial adhesion within the composite leads to very poor dispersion of the cellulose fibers, which tend to aggregate, thus resulting in poor material properties. Different routes have been employed to defeat this problem, ranging from the use of grafting agents, and reactive extrusion, to the functionalisation of one or both components . Among these, the use of compatibilisers or coupling agents is particularly attractive, as these often polymeric molecules can be precisely synthesized and tuned in a controlled manner, thus allowing the effects of the molecular structure on the dispersion of cellulose to be closely investigated and optimized.…”

Cellulose composites with polyethylene (PE) permit to reinforce this commodity polymer, while at the same time introducing renewable content and thus minimizing the use of petroleum‐based feedstocks. Herein, we report on two fully renewably sourced and sustainably synthesized compatibilisers based on amylose and starch, which allow for such cellulose dispersion in low‐density PE (LDPE). These compatibilisers advantageously combine the hydrophilicity of carbohydrates with the hydrophobicity of fatty acids. Upon extrusion of cellulose, LDPE, and the compatibilisers, a significantly improved dispersion of cellulose within LDPE was observed using rheology at loadings of 10 wt % cellulose and 5–15 wt % compatibiliser. Moreover, an improved interfacial adhesion was observed using scanning electron microscopy and was also confirmed by the mechanical properties, notably the Young's modulus, as a result of the good stress transfer between filler and matrix material. This study highlights the potential of fully renewable compatibilisers for the preparation of composites of cellulose and the commodity plastic LDPE. © 2019 The Authors.
