Repeatable mechanochemical activation of dynamic covalent bonds in thermoplastic elastomers

Mechanochemistry: the mechanical activation of covalent bonds.

Regarding the activation of chemical reactions, today’s chemist is used to thinking in terms of thermochemistry, electrochemistry, and photochemistry, which is reflected in the organization and content of the standard physical chemistry textbooks. The fourth way of chemical activation, mechanochemistry, is usually less well-known. The purpose of the present review is to give a survey of the cla...

Functional systems with orthogonal dynamic covalent bonds.

This review summarizes the use of orthogonal dynamic covalent bonds to build functional systems. Dynamic covalent bonds are unique because of their dual nature. They can be as labile as non-covalent interactions or as permanent as covalent bonds, depending on conditions. Examples from nature, reaching from the role of disulfides in protein folding to thioester exchange in polyketide biosynthesi...

Thermoplastic Elastomers with Photo-actuating Properties

This contribution reviews elastomeric materials with photo-actuation behavior with emphasis on thermoplastic elastomers and their composites. The principles of the photo-actuation and the main factors affecting the photo-actuation phenomena of thermoplastic elastomer materials are discussed in detail. The well-performing photoactuating systems involving both statistical and block copolymers-bas...

Single-Chain Polymer Nanoparticles via Non-Covalent and Dynamic Covalent Bonds

The added-value behind reversible bonds is the possibility to develop responsive structurally dynamic materials which can adapt their constitution and, hence, properties to external stimuli. In recent years, much effort has been devoted to the design and synthesis of single-chain polymer nanoparticles (SCNPs) that can be reversibly assembled / disassembled in response to external environmental ...
