Abstract
In order to protect the ecosystem from the impact of plastic film pollution, it is necessary to explore biodegradable materials for producing a plastic film. In this study, mulch film was prepared using biochar as the fertilizer carrier, Enteromorpha polysaccharide (EP), and konjac glucomannan (KGM) as the film’s matrix. The result of Fourier transform infrared (FTIR) showed that the Enteromorpha polysaccharide extracted from Enteromorpha prolifera (E. prolifera) was rich in hydroxyl, carboxyl, and sulfonic groups. The result of FTIR, scanning electron microscopy (SEM), and energy-dispersive spectroscopy of biochar proved that urea was successfully loaded in biochar, and the urea loading capacity of biochar reached 17.8%. The transmittance of EP/KGM/urea-loaded biochar film (urea-BCF) was less than 3%, which meets the requirements of the black mulch film. The degradation rate of the mulch in the soil can reach 68.3% after 80 days of burial, indicating an excellent degradation performance. The SEM results showed that the biochar particles were distributed uniformly in the membrane matrix. In addition, the leaching experiments showed that the release of urea achieved an equilibrium after 20 h, with a cumulative of almost 76.9%. This method not only achieves the high value utilization of E. prolifera but also provides a simple strategy for preparing mulch film.
期刊介绍:
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
