Effect of Addition of Halloysite Nanoclay and SiO2 Nanoparticles on Barrier and Mechanical Properties of Bovine Gelatin Films (2012, background): “The improved barrier properties is also attributed to the tortuous path around the clay layers that forces the permeant molecules to travel a longer distance through the film (Nielsen 1967; Bharadwaj 2001; Park et al. 2003; Rhim et al. 2005; Adame and Beall 2009; Sothornvit et al. 2010).”
A review of the water barrier properties of polymer/clay and polymer/graphene nanocomposites (2016, methodology): “Adame and Beall [111] have reported direct measurement of the constrained polymer region in polyamide/clay nanocomposites using AFM.”
Nanocomposites for food packaging applications (2009, background): “Since clay layers constitute a barrier to gases and water, forcing them to follow a tortuous path, the introduction of nanoclays into polymer biostructures has been shown to greatly improve barrier properties (Adame & Beall, 2009), minimizing one of the main limitations of biopolymer films.”
Environmental friendly food nano-packaging (2017, background): “The tortuous pathway increases the mean gas diffusion length and, thus, the shelf life of spoilable foods (Adapted from Adame and Beall 2009)”
Nanoscience and nanotechnologies in food industries: opportunities and research trends (2014, result): “This theory was developed by Nielsen (1967) and was further corroborated by other authors (Adame and Beall 2009).”
Recent progress in biodegradable polymers and nanocomposite-based packaging materials for sustainable environment (2018, methodology): “That will not be significant in crystalline region”.([64]) Clay layer forms a barrier to gas and water resulting in a complicated path within the film.”
