“…A synergistic effect of certain factors affecting the reactivity of the polymer was found. Thus, exposure to UV light and heat treatment comprise a simple method leading to the formation of functional groups in the hydrophobic polymer chains, which makes them sensitive to subsequent microbial attack [3]. However, there are many contradictory reports concerning the behaviour of degradable composite polymers during their storage and exposure to environmental factors.…”

“…biodegradation effect was obvious in PE films containing 30% cellulose. Also, Kaczmarek and Oldak [27], who investigated the effects of UV irradiation on the composting of PE modified with cellulose, found that very small amounts of cellulose (5-15%) in a PE composite did not change its degradability compared to PE alone while a difference in properties was found for a blend of PE and 30% cellulose.…”

Toward the development of biocomposites for packaging applications, the possibility of using kenaf cellulose (KC) was investigated in the production of low-density polyethylene (LDPE)/KC/polyethylene glycol (PEG) biocomposites. First, cellulose was extracted from the cell walls of kenaf-bast fibers. Then, different weights of LDPE, KC, and PEG were blended, and the effects of varying the concentrations of KC and PEG on the synthesis process were evaluated, and the resulting composites were characterized with respect to their mechanical, thermal, biodegradability and water-absorption properties. A scanning electron microscope (SEM) was also used to observe the surface morphology of the samples before and after biodegradation tests. The results showed that the mechanical properties of the biocomposites decreased slightly as the KC content was increased from 0 to 50wt% in the biocomposite formulation; however, there was a good homogeneity between samples with added PEG. The addition of KC improved the thermal resistance of these biocomposites; PEG also had positive role in the thermal behavior of the composites. Based on a soil-burial test, the biodegradability of the composites showed a clear trend of increase degradation with increasing KC content in the formulation. While water-absorption values for the composites were higher than that of pure LDPE polymer, the addition of PEG to the formulation reduced the water absorption of the composites.

“…One of the most common polymers is the low-density polyethylene (LDPE), which has a crystallinity about 50-60%, a melting temperature in the range of 110-115 °C and branched chains that determines the degree of crystallinity and the transition temperatures [13] . The results from a previous study on the degradation of this polymer in different conditions showed positive effects, especially when the photo and biodegradation experiments have been carried out in combination [14][15][16] .…”

SbstractThe increased consumption of plastics in the world has been a subject of great concern and special attention by the scientific community. The aim is to promote development of materials that are biodegradable in a shorter time upon disposal in the environment. The most used synthetic plastics are difficult to biodegrade because they are made of long hydrocarbon chains, such as polyethylene (PE), polypropylene (PP), poly(vinyl chloride) (PVC), which are hydrophobic and resistant to the action of microbial enzymes. The use of alternative materials (natural polyesters) can minimize the harm to dumps and landfills upon their disposal, because they are susceptible to the action of microorganisms. In this study we evaluated the biodegradation/biodeterioration of PHBV (poly(3-hydroxybutyrate-co-hydroxyvalerate) films, LDPE (low density polyethylene) and the blend of LDPE/PHBV (70/30) by the fungus Paecilomyces variotii, using different methods: optical microscopy (OM), scanning electronic microscopy (SEM) and Fourier Transform Infrared spectroscopy (FTIR).
