“…Micro/nanoencapsulation process of core materials using PMMA can be carried out by many techniques such as emulsion/miniemulsion polymerization, suspension polymerization, seeded polymerization, solvent evaporation from oil‐in‐water (o/w) emulsion (internal phase separation), surface‐initiated photopolymerization, and membrane emulsification . The emulsion polymerization and solvent evaporation are the most common techniques for the production of PMMA capsules, due to their simplicity in encapsulation of hydrophobic materials.…”

Material encapsulation is a relatively new technique for coating a micro/nanosize particle or droplet with polymeric or inorganic shell. Encapsulation technology has many applications in various fields including drug delivery, cosmetic, agriculture, thermal energy storage, textile, and self-healing polymers. Poly(methyl methacrylate) (PMMA) is widely used as shell material in encapsulation due to its high chemical stability, biocompatibility, nontoxicity, and good mechanical properties. The main approach for micro/nanoencapsulation of materials using PMMA as shell comprises emulsion-based techniques such as emulsion polymerization and solvent evaporation from oilin-water emulsion. In the present review, we first focus on the encapsulation techniques of liquid materials with PMMA shell by analyzing the effective processing parameters influencing the preparation of PMMA micro/nanocapsules. We then describe the morphology of PMMA capsules in emulsion systems according to thermodynamic relations. The techniques to investigation of mechanical properties of capsule shell and the release mechanisms of core material from PMMA capsules were also investigated.

“…Recently, durable fragrances and perfumes have been introduced into textiles . Other potential applications include production of carbonless copying paper, liquid crystals, pharmaceuticals, food additives, cosmetics, coatings, electronic inks, catalysts and dyes etc . However, the availability of microcapsule textiles in commercial markets is growing slowly, which is attributed to poor durability and performance of the functional textiles with microcapsules.…”

The textile industries have incorporated perfume microencapsulation technology to improve their products. However, certain industrial microcapsules show low encapsulation capacity and low material stability. In this study, vanillin/chitosan microcapsules were prepared via spray‐drying, and the encapsulation efficiency and loading capacity of the microcapsule were 50.69% and 30.31%, respectively. Quantum–chemical calculations confirm the interactions of hydrogen bonds between vanillin and chitosan. Their applicability to the cotton fabric with citric acid as the cross‐linking reagent has been investigated. The structure of the microcapsule‐treated cotton fabric has been characterized with various physico‐chemical techniques. The results confirm the microcapsules have been successfully grafted onto the cotton fabrics. The release experiments show that 21.9% vanillin was retained under 65°C and 80% humidity conditions and 8.6% vanillin still existed after 14 washes. Copyright © 2013 John Wiley & Sons, Ltd.

ABSTARCT: The present survey shows that microcapsules are used as effective tools for modification and functionalization of fibrous products. The core and shell materials of microcapsules can comprise various active ingredients in accordance with different requirements of final fibrous products. In this survey, the morphology, functional properties and added values of microcapsules, also such advanced types as nanocapsules, bi-, multifunctional microcapsules, and their applications in smart and other modern products are described. Some relevant applications of microcapsules in industrial processes are briefly discussed. The techniques used to encapsulate the core ingredients are also overviewed. and Portugal.
