In this article, we present a semi-interpenetrating network (IPN) hydrogel of reasonable size with improved swelling behavior. The semi-IPN is composed of N-isopropylacrylamide and 2-acrylamido-2-methyl-1-propanesulfonic acid. Porosity was generated chemically by a surfactant-based template method. The swelling behavior was measured after an abrupt change of the temperature to 25 °C or 40 °C or after an abrupt change of the salt concentration of the aqueous medium surrounding the hydrogel samples. A set of static swelling degrees was determined from swelling measurements in salt solutions of varying concentrations and at different temperatures. Introducing porosity to the semi-IPN decreases the swelling times for most measurements while the sensor and actuator characteristics of the hydrogel found in previous studies are preserved. Additionally, we propose theoretical assumptions and explanations regarding the differences in the swelling kinetics of the porous and the nonporous semi-IPN and deduce implications for sensor and actuator applications.

Gypsum dissolution as a function of time was measured in solutions having a sodium adsorption ratio (SAR) of 7.5, 14 and 27 (mmol(+) kg-1)1/2 and an electrical conductivity (EC) of 1 5 and 3.1 dS m-1. The amount of gypsum dissolved increased with increases in the SAR and EC values of the different equilibrating solutions. The rate of gypsum dissolution was higher initially but declined with increasing time of equilibration. Of the total amount of gypsum dissolved in 40 h, about 60-70% dissolution occurred during the first 5 min. Comparisons of coefficients of determination (r2) and standard errors of estimate indicated that, in addition to the most widely used linear form of the first-order model, other models such as the power function, empirical (modified from first-order) and the Elovich equation, can also be used to describe the kinetics of gypsum dissolution in aqueous solutions varying in SAR and EC.
