“…As shown in Figure 6a-6c, Sheng et al have fabricated electrochromic dye-doped LC microcapsules (DDLC-Ms) via an emulsion polymerization strategy, and have further processed them into a DDLC-based smart fabric through a simple printing strategy. [144] When the current is switched off, molecules in DDLC-Ms are randomly oriented with the light absorbed and scattered by the dichroic dye molecules. As a result, the smart fabric shows red under direct view and microscope.…”

“…Varieties of these include microencapsulated colorants for One of the initial microencapsulation applications to achieve innovative effects in textile processing have been microencapsulated dyes and pigments for special textile printing and dyeing. Varieties of these include microencapsulated colorants for permanent dyeing and printing of textiles [19][20][21], as well as colour changing textiles based on thermochromic microcapsules [22][23][24][25], photochromic dyes [26][27][28][29], and electrochromic textiles containing microencapsulated liquid crystals [30][31][32].…”

Microencapsulation for Functional Textile Coatings with Emphasis on Biodegradability—A Systematic Review

2021

View full text Add to dashboard Cite

The review provides an overview of research findings on microencapsulation for functional textile coatings. Methods for the preparation of microcapsules in textiles include in situ and interfacial polymerization, simple and complex coacervation, molecular inclusion and solvent evaporation from emulsions. Binders play a crucial role in coating formulations. Acrylic and polyurethane binders are commonly used in textile finishing, while organic acids and catalysts can be used for chemical grafting as crosslinkers between microcapsules and cotton fibres. Most of the conventional coating processes can be used for microcapsule-containing coatings, provided that the properties of the microcapsules are appropriate. There are standardised test methods available to evaluate the characteristics and washfastness of coated textiles. Among the functional textiles, the field of environmentally friendly biodegradable textiles with microcapsules is still at an early stage of development. So far, some physicochemical and physical microencapsulation methods using natural polymers or biodegradable synthetic polymers have been applied to produce environmentally friendly antimicrobial, anti-inflammatory or fragranced textiles. Standardised test methods for evaluating the biodegradability of textile materials are available. The stability of biodegradable microcapsules and the durability of coatings during the use and care of textiles still present several challenges that offer many opportunities for further research.

By using solvated metal cations as structure-directing agents, three new iodoargentates, namely,[ Fe(DMSO) 6 ] [Ag 6 I 9 ]·DMSO (1), [Fe(H 2 O) 6 ][Ag 15 I 18 ]( 2)a nd [Cd(DMSO) 6 ] [Ag 8 I 10 ]( 3)( DMSO = dimethyl sulfoxide) have been solvothermally prepared and structurallyc haracterized. The structures of compounds 1 and 2 can be described as 1D chains constructed from the linkageo f[ Ag 6 I 9 ]a nd [Ag 5 I 11 ]b uilding units, respectively.F or compound 3,t he [Ag 10 I 22 ]b uilding blocks are directly interconnected to form a2 D[ Ag 8 I 10 ]l ayer,which are furtheri nterconnected via intermolecularf orces to generate a3 Ds upramolecular framework with 1D large channels occupied by [Cd(DMSO) 6 ] 2 + cations.I nterestingly, compounds 1-3 exhibit an ion-exchange behavior for the adsorption of as pecific dye (methylene blue, MB). Moreover, photocatalytic experimentsi ndicate that these iodoargentates can be considered as promisingp hotocatalysts for the degradation of organic dyep ollutants.[a] Dr.
