Abstract

Keywords Sessile drop · Basal radius · Diffusivity of chemical agents · Diffusivity of toxic chemicals · Time evolution of sessile drop profile · Evaporation of sessile drops · Absorption of sessile drops · Model for diffusivity estimation · Diffusivity from contact angle · Barrier polymers Introduction Evaluating the diffusivity of chemical agents and highly toxic industrial chemicals in solid substrates is important for the development of protective barrier materi- als such as gloves, face masks, or soldier uniforms. The diffusivity data are also needed, to assess the extent of contamination when equipment or vehicles with pol- ymer-coated surfaces are subjected to chemical agent attacks or exposed to chemi- cal spillage, and to develop decontamination strategies. The classical approach to determining the liquid diffusivity in a solid is the immersion method wherein the solid substrate is immersed in the liquid chemical of interest and the mass addition 1 3 Polym. Bull. to the substrate from liquid sorption is measured as a function of time [1]. From the immersion method one can obtain both the equilibrium uptake of the liquid into the solid substrate and the diffusivity of the liquid in the substrate.
