Abstract The effect of energetic neutral nitrogen atoms (ENA) treatment at different plasma power (5 W, 10 W, 15 W and 20 W) for 10 min on the physico-chemical, mechanical, barrier and thermal properties of kithul starch films were studied. The surface of kithul starch film after ENA treatment showed higher roughness. Energetic neutral nitrogen atom treatment increased crystallinity. Tensile properties significantly (p ≤ 0.05) increased after ENA treatment. Water vapour permeation (WVP), oxygen permeability, solubility and moisture absorption decreased in ENA treated kithul starch films. Higher opacity and lower WVP and oxygen permeability confirmed better barrier properties of ENA treated kithul starch films. Hence, treated kithul starch films with improved mechanical and barrier properties have a potential role in the area of biodegradable films.

对 kithul (Caryota urens) 淀粉可生物降解薄膜进行高能中性 N2 原子处理：物理化学表征

摘要 研究了不同等离子体功率（5 W、10 W、15 W 和 20 W）下高能中性氮原子 (ENA) 处理 10 min 对 Kithul 淀粉薄膜的理化、机械、阻隔和热性能的影响。 . ENA处理后的kithul淀粉膜表面显示出更高的粗糙度。高能中性氮原子处理增加了结晶度。ENA 处理后，拉伸性能显着增加（p ≤ 0.05）。ENA处理的kithul淀粉薄膜中的水蒸气渗透（WVP）、透氧性、溶解性和吸湿性降低。更高的不透明度和更低的 WVP 和透氧性证实了 ENA 处理的 Kithul 淀粉膜具有更好的阻隔性能。因此，具有改善的机械和阻隔性能的处理过的 kithul 淀粉薄膜在生物可降解薄膜领域具有潜在的作用。
