Polyolefin foams possess a number of unusual properties, including light weight, a high strength-to-weight ratio, better thermal insulation, chemical resistance, less water absorption, cushioning performance, and so forth. Despite many advantages of polyolefin foam, their applications have been recently limited due to non-recyclability and non-biodegradability. To overcome this problem, we fabricated low-density polyethylene (LDPE) biocomposites with chemically modified lignin content up to 30 wt.-% because lignin, the second most abundant component in the plant cell wall of lignocellulosic materials, is being extensively used for this purpose. Thereafter, the lignin-reinforced LDPE biocomposites will be foamed with traditional chemical blowing agent, azodicarbonamide (ADCA). In this study, we will focus to evaluate the influence of the chemical modification of lignin and lignin content on the cell morphology and physical properties of them. |
