Encapsulation-based systems are of interest for the industry in applications such as chemical-additive preservation, small molecule release, particle delivery, and self-sealing materials. Many methods are used to encapsulate relevant chemical additives for the controlled release of contents such as polymeric vesicles, inorganic shells, and mesoporous materials. In the complete paper, a novel system that uses engineered features of permeable polymeric shell walls for the controlled release of encapsulated cargo is described.
Introduction
Competent cement systems are designed to allow the placement of cement behind the casing at a set time by using chemical additives. The function of these chemical additives is extensive and used to control cement properties such as setting time, rheology, fluid loss, gas migration, density, and enhanced mechanical properties.
