“…Additionally, sulfur compounds possessed certain antioxidant properties that could extend the shelf life of SP ( Hill et al, 2022 ). However, high concentrations of sulfur-containing aroma compounds could cause discomfort to humans ( Sun et al, 2023 ). Fortunately, the concentration of sulfur-containing compounds in all samples was found to be very low, and some samples did not contain any detectable levels of these compounds.…”

“…Light degradation was an important step in the polymer degradation process. When a polymer absorbs a series of light rays, the internal chemical bond is broken [35], and the electrons within the molecule are excited to a higher energy level after absorbing highenergy radiation, resulting in polymer oxidation and hydrolysis [36,37]. In this paper, there was no influence of natural light in the degradation process of membrane materials, and the membrane materials prepared by Song were accompanied by 12 h of light during the degradation process [31].…”

The self-made slow-release membrane material with water-based copolymer (polyvinyl alcohol PVA, polyvinyl pyrrolidone PVP), zeolite and epoxy resin as raw materials was tested for degradation in buried soil. The effects of soil temperature T (T 15 , T 25 , T 35 ) and moisture W (W 60 , W 80 , W 100 ) on the degradability of membrane materials were investigated by a comprehensive experimental design, and a hydrothermal coupling model K (T, W) was established. The effects of degradation on the chemical structure, functional groups, and morphology of membrane materials were revealed by infrared spectroscopy and SEM electron microscopy. The results showed that the degradation degree of membrane material was an exponentially positive response to the increase in soil temperature and moisture. The degradation rate of membrane materials under different treatments was 13.7%-17.3%, and the maximum degradation rate was 17.3% under the T 35 W 100 condition. The determination coefficient R 2 of the constructed K (T, W) model reached 0.927, and the average relative error of the predicted degradation rate was 1.58%, indicating good accuracy of the model. The infrared spectrum showed that the -OH stretching vibration absorption peak of the degraded membrane becomes wider and the peak intensity increases; the absorption peak intensity of C-H, -CH 2 , and Si-O weakens; and the peak of the C=C absorption peak appears as a continuous staircase after degradation. The SEM electron microscopy showed there were differences in the pores and cracks of the membrane materials under different treatments, and the degradation was the most obvious under the T 35 W 100 condition.
