Theoretical Background Water Vapor Sorption Isotherms
The term sorption is generally used to describe the initial penetration and the dispersal of the permeant molecules into food matrices (Chirife and Iglesias 1978) and, more generally, into all kinds of polymers (Naylor 1989; Tsujita 1992). This term includes adsorption, absorption into microvoids, and cluster formation. When a food matrix is placed in a humid atmosphere, the relationship betwee...
متن کاملSorption of Nitrogen and Water Vapor on Textile Fibers 1
:-Ieas urements were made of the adsorption of nit rogen and water vapor on six purified text ile fibe rs and t itaniu m dioxide. It was found that all of t he fi bers had a relatiYely low capa city for the adsorption of nitrogen as compared with t h c capacity for t h e adsorption of ,,'ater vapor. T he surface area values ranged from 0,31 sq uare meter per gram for nylon to 0.98 square meter ...
متن کاملWater Vapor Sorption and Diffusion in Secondary Dispersion Barrier Coatings: A Critical Comparison with Emulsion Polymers.
The conventional method for synthesizing waterborne polymer colloids is emulsion polymerization using surfactants. An emerging method is the use of secondary dispersions (SD) of polymers in water, which avoids the addition of any surfactant. Although there are numerous studies of the water barrier properties (sorption, diffusion, and permeability) of waterborne emulsion (Em) polymer coatings, t...
متن کاملWater Vapor Sorption by the Pedal Mucus Trail of a Land Snail
The hydrophilicity of pedal mucus trails deposited by marine snails influences the settlement of other organisms and can potentially influence the trailing and homing mechanisms of terrestrial snails. The composition of pedal mucus deposited as a trail on a solid substrate by the giant African land snail (Achatina marginata) has been probed non-invasively using infrared ellipsometry. The primar...
متن کاملComparison of Water Sorption of Two Injection Acrylic Resins with a Conventional Pressure-Packed Acrylic Resin
Background and Aim: Water sorption is one of the most important properties that affects the quality of a prosthesis, and subsequently, the quality of treatment, and pa-tient’s quality of life. The aim of this study was to determine and compare the water sorption of two types of poly methyl methacrylate (PMMA) using the injection-molding systems with a traditional acrylic resin base material. M...
