A montmorillonite@chitosan-poly (ethylene oxide) nanofibrous membrane (MMT@CPF) enhancing poly (vinyl alcohol-co-ethylene) (EVOH-MMT@CPF) composite film was developed by using a space-filling embedding method. The structure of EVOH-MMT@CPF was characterized, and the thermal stability, mechanical and barrier properties of the films were investigated. The CPF was fabricated via electrospinning technique and the self-assembly of MMT nano-platelets on CPF was achieved by the driving of electrostatic interactions between MMT nano-platelet and CPF. The experimental results indicated that the well-kept MMT@CPF after embedding in the EVOH matrix significantly improved the thermal stability and mechanical properties of the film, and also endowed the film with outstanding oxygen barrier (0.2 × 10⁻¹⁶ cm³ cm cm⁻² s⁻¹ Pa⁻¹) and good moisture barrier (4.6 × 10⁻⁶ g m m⁻² s⁻¹ atm⁻¹ under a relative humidity of 90%) by prolonging the tortuous paths for molecule penetration. The composite film may have a great potential application in food packaging.

采用空间埋置法制备了蒙脱土@壳聚糖-聚环氧乙烷纳米纤维膜（MMT @ CPF）增强聚（乙烯醇-共-乙烯）复合膜（EVOH-MMT @ CPF）。表征了EVOH-MMT @ CPF的结构，并研究了薄膜的热稳定性，机械性能和阻隔性能。通过静电纺丝技术制备了CPF，并通过驱动MMT纳米血小板与CPF之间的静电相互作用实现了MMT纳米血小板在CPF上的自组装。实验结果表明，在EVOH基体中嵌入完好的MMT @ CPF可以显着改善薄膜的热稳定性和机械性能，并赋予薄膜以优异的阻氧性（0.2  ×  10^-16  cm ³  cm  cm ^-2  s ^-1  Pa ^-1）和良好的防潮层（4.6  ×  10 ^-6  g  m  m ^-2  s ^-1  atm ^-1在90％相对湿度下），延长了曲折路径分子渗透。该复合膜在食品包装中可能具有巨大的潜在应用。
