“…A similar behavior has been reported in the literature for polyethylene films containing pro-oxidant agents [31,32]. On the other hand, the reduction of the deformation at rupture of the HDPE-MA-RH and HDPE-MA-EG-RH composites is attributed to the presence of rice husk particles that render the samples less ductile owing to a reduction of the motility of the polyethylene chains [33]. Moreover, it was confirmed that the HDPE-MA-EG-RH sample showed reduced deformation at rupture when compared to sample HDPE-MA-RH, with statistical differences when subjected to accelerated aging and 90 days of biodegradation, thus demonstrating the effect of UV radiation on the composites under study.…”

The use of agricultural waste, such as rice husk (RH), for the production of cheap and eco-friendly polymer composites has emerged as a promising field of interest. The aim of this work was the preparation of highdensity polyethylene (HDPE)-based composites reinforced with rice husk and an organic pro-oxidant (EG15) for the production of seedlings tubes. Photodegradation and degradation tests in simulated soil were performed for 90 and 180 days in order to study the decomposition of these composites. The SEM and OM images suggest that degradation of the composites samples was more extensive than the pure HDPE samples, probably because the composites present intense light absorption in the UV range, facilitating the degradation process even before biodegradation begins. In addition, after introducing RH particles in the polymeric matrix, the mechanical tensile and flexural properties, experienced significant changes, suggesting that the RH particles were homogeneously dispersed throughout the polymer matrix. Finally, the results have demonstrated that HDPE, RH, and EG15 are attractive materials for the design of polymeric composites for the production of seedlings tubes with excellent mechanical properties, being also easily decomposed in the environment once discarded.

Rice husk (RH)/montmorillonite (MMT) hybrid filler‐filled low‐density polyethylene nanocomposite films were prepared by extrusion blown film. RH was used as a biodegradable filler in various concentrations (2, 5, and 7 parts per hundred composite), while the amount of MMT was held constant at 2 wt%. Delamination of MMT platelets and distribution of RH were investigated by X‐ray diffraction and scanning electron microscopy. Diffractograms revealed the formation of intercalated structures, regardless of the RH content. Barrier properties revealed that MMT platelets have the potential to retard the diffusion of permeating molecules while, on the other hand, barrier efficiency of MMT is balanced by the subsequent incorporation of RH in RH/MMT hybrid filler‐filled composite films. Despite an increase in permeability, the selectivity ratio (CO2/O2 permeability) increased with increasing RH contents in the hybrid filler‐filled composite films showing the potential of these films in the development of modified atmosphere for fresh fruits and vegetables. The colonization of fungus and formation of holes as observed in micrographs of the test samples subjected to soil burial revealed that the biodegradation rate increased with the incorporation of RH in the hybrid composites. The composite films with higher contents of RH in hybrid filler are also more biodegradable than those having lower contents. Addition of RH contents in the hybrid filler increased the tensile modulus, while decreasing the tensile and tear strength. Addition of RH in the hybrid filler increased the melting and crystallization temperatures of the resulting nanocomposite films as well. J. VINYL ADDIT.

“…14,22 For compatibilised nanocomposite film, the comparison of diffraction peak location reveals that peak position moved toward lower 2θ and continued to move as the MAPE and EVA content increased. Adding 3 phc MAPE or 12 phc EVA into LDPE/MMT uncompatibilised system resulted in 32% and 25% improvement in interlayer distances of the MMT.…”
