Barrier and Mechanical Properties of Clay-Reinforced Polymeric Nanocomposites
(Taylor & Francis Inc, 2011-01-01)
In this work, clay-based nanocomposites films were prepared by addition of clay-Na+ natural montmorillonite in pectin and hydroxypropyl methylcellulose (HPMC) matrices. Mechanical (tensile strength, elastic modulus, and ...
Development of Novel Guava Puree Films Containing Chitosan Nanoparticles
(Amer Scientific Publishers, 2012-03-01)
One of the overall goals of industries is to use packages that do not cause environmental problems at disposal time, but that have the same properties as the conventional ones. The goal of this study is to synthesize edible ...
