摘要

用于包装应用的聚乙烯醇一直面临着紫外线降解的挑战，这往往会降低其耐久性，而在使用中。研究了纳米晶纤维素增强聚乙烯醇(PVA)的紫外光稳定性。用棕榈油废NCC增强聚乙烯醇复合膜(PVA-NCC膜)，并在不同时间(22 W, SUV-16 254 nm)下暴露，研究材料的耐久性增强。测定样品的失重率，观察紫外光降解效果。利用红外光谱(FT-IR)、扫描电镜(SEM)和拉伸试验研究了紫外光照射前后样品的结构、形态和拉伸性能。结果表明，NCC的加入使PVA的物理性能下降，形貌和拉伸性能增强。在紫外光下，NCC的加入显著降低了PVA的降解率。此外，观察到体重减轻的百分比随紫外线照射时间的变化而变化。

Ultraviolet light exposure degradation effect on the properties of nanocrystalline cellulose-reinforced polyvinyl alcohol composite film

PVA used in packaging applications has been faced with a UV light degradation challenge, which often reduces its durability while in use. The UV light stability enhancement effect of nanocrystalline cellulose (NCC) reinforcement in PVA was studied. Polyvinyl alcohol composite film was reinforced with NCC from palm oil waste (PVA-NCC film) and exposed to UV light (22 W, SUV-16 254 nm) for different time duration to study the material durability enhancement. The percentage weight loss of the samples was measured to observe the UV light degradation effect. Furthermore, the samples’ structural, morphological, and tensile properties were studied before and after exposure to UV light with FT-IR, scanning electron microscopy (SEM), and tensile test. The results showed physical degradation, morphological and tensile properties enhancement of PVA with NCC’s addition. The addition of NCC to the PVA matrix reduced the degradation rate under UV light significantly. Also, the percentage of weight loss was observed to change with the exposure time to UV light.
