Abstract Halloysite nanotubes (HNTs) are hollow tubular clay nanoparticles used as nanofillers to remove or minimize the production of ethylene gas. The presence of ethylene gas leads to reduced shelf life in fruits and vegetables by accelerating postharvest softening and aging. Alkaline solution-treated HNTs have increased ethylene adsorption capacity due to an increased number of OH groups on the HNTs external surface. This study reports on the thermal, morphological, and mechanical properties of alkaline HNTs (ALK-HNTs) loaded into a low-density polyethylene (LDPE) matrix. Our results indicate that, although the mechanical properties of the LDPE matrix films were not improved with loading ALK-HNTs, the oxygen barrier property were improved and ethylene gas adsorption increased by 220 %. Cherry tomatoes packaged in a 3% ALK-HNTs/LDPE nanocomposite film and stored at 8 °C for 21 days showed a reduction in loss of firmness and weight by 17.0 % and 36.7 %, respectively.

具有增加乙烯吸收能力的碱性埃洛石纳米管/低密度聚乙烯纳米复合薄膜：在樱桃番茄包装中的应用

摘要埃洛石纳米管 (HNT) 是中空管状粘土纳米颗粒，用作纳米填料以去除或减少乙烯气体的产生。乙烯气体的存在会加速水果和蔬菜的采后软化和老化，从而缩短其保质期。由于 HNTs 外表面上的 OH 基团数量增加，碱溶液处理的 HNTs 具有增加的乙烯吸附能力。本研究报告了加载到低密度聚乙烯 (LDPE) 基质中的碱性 HNT (ALK-HNT) 的热、形态和机械性能。我们的结果表明，虽然负载 ALK-HNTs 的 LDPE 基质薄膜的机械性能没有改善，但氧气阻隔性能得到改善，乙烯气体吸附增加了 220%。
