“…Considering other self‐healing systems operating with dual‐chemistry approaches, Zhang and coworkers showed that healing material involving thiol‐epoxy‐ene functionalities could be encapsulated into polyvinyl chloride, a commodity thermoplastic. The material showed excellent self‐healing capacity . Among other mixed‐chemistry systems, the group of Bowman presented a detailed study regarding curing behavior and properties of the final materials in a system composed of the thiol‐ene and thiol‐epoxy chemistries operating independently of each other and with capability of changing the curing sequence .…”

Base-catalyzed reaction between a thiol and an epoxide group is a simple fusion process that leads to the formation of a b-hydroxythio-ether linkage. This reaction is efficient, regio-selective, and fast. In addition, it produces a reactive hydroxyl group upon completion. Therefore, it is of considerable potential in synthesis of reactive and functional soft materials. Here, we discuss the fundamental aspects of this process, the so-called thiol-epoxy "click" reaction, and its utility in the preparation and post-polymerization functionaliza-tion of polymers and crosslinked networks. Furthermore, its application in surface modification of solid substrates is also considered. Finally, utility of multifunctional materials created using the thiol-epoxy reaction is discussed in the biomedical arena.

Microencapsulation is a widely‐investigated technique used for the unstable material preservation since the wall materials prevent the core materials from loss and deterioration. To improve the stability of cinnamaldehyde (CAL), different microcapsule wall systems are fabricated by spray‐drying, and then characterized by experimental methods to determine the most suitable wall materials. Surface morphology, encapsulation efficiency, effective loading capacity, as well as moisture absorption property are evaluated, and the results suggest that a three‐matrix system of methyl cellulose (MC)/sodium alginate (SA)/MC or MC/carboxymethyl chitosan (CMC)/SA wall formulation is more suitable for CAL microencapsulation. Moreover, a novel quantitative method is also proposed to verify the most stable wall material microencapsulation. The quantitative results show that the highest activation energy (53.00 ± 2.24 kJ/mol) is observed for the MC/CMC/SA‐encapsulated CAL microcapsule. Taken together, the results suggest that MC/CMC/SA wall formulation shows excellent barrier properties and is superior to other wall materials in preventing microencapsulated CAL deterioration. This study will be efficient in designing an ideal capsule for CAL microencapsulation.

Synthesis and characterization of ring-type and branched polymers including polyethylene glycols by “click” chemistry

et al. 2019

Synthesis of ring-type (or branched) polymers including polyethylene glycols was archived via "click" chemistry of 5,6-diazido-2-benzyl-1H-benzimidazole (Di-N 3) [or triazidoacetohydrazide derivative (Tri-N 3)] and terminally dipropargyl polyethylene glycols (PEG-dipropargyl) with different molecular weights. DiN 3 was obtained by reaction of 5,6-dichloro-2-benzyl-1H-benzimidazole (Di-Cl) and sodium azide. 2-(2-benzyl-5,6-dichloro-1H-benzimidazol-1-yl)-N′-(4-chlorobenzylidene)acetohydrazide (Tri-Cl) was synthesized by using Di-Cl. Synthesis of Tri-N 3 was archived by means of reaction of Tri-Cl and sodium azide. PEG-dipropargyl was synthesized by using reaction of PEGs with different molecular weights and propargyl chloride. By using DiN 3 (or Tri-N 3) and PEG-dipropargyl, ring-type (or branched) polymers including polyethylene glycols were synthesized. The polymers were relatively acquired in high yields and low dispersities. The primary parameters for example concentration and time were assessed. The characterization of products was accomplished by using multi instruments such as 1 H-NMR, FT-IR, GPC, TGA, DSC, and elemental analysis techniques. The multi instruments studies of the obtained polymers show that the ring-type and branched polymers easily formed as a result of "click" chemistry.
