DOI: 10.1016/j.porgcoat.2020.105661
Abstract: Abstract Herein, we report an innovative cross-linked network of silicone elastomer with good stretchability, thermal stability and autonomous self-healing. This type of elastomers was easily prepared by aminopropyl terminated polydimethylsiloxane (A-PDMS), thioctic acid (TA) and… read more here.

DOI: 10.1021/acsmacrolett.8b00166
Abstract: Current vitrimer technology uses only a handful of distinct reactions for cross-linking. New dynamic reactions can diversify vitrimer functionality and properties. In this paper, reversible cross-links formed by conjugate addition–elimination of thiols with a Meldrum’s… read more here.

DOI: 10.1039/d1gc01709h
Abstract: Silicone elastomers must be filled/reinforced with fillers, typically fumed silica, as they are otherwise soft and/or weak and prone to tearing. Fumed silica, produced from waste chlorosilanes by combustion, is relatively expensive and involves the… read more here.
