Super-stretchable self-healing polymer
Abstract
An elastic composition comprising the following structure: wherein: PDMS is polydimethylsiloxane having at least 5 dimethylsiloxane units; L is a bond or hydrocarbon linker; the asterisk (*) in A units denotes a connection point with an asterisk in B units, and at least one of the following linkages connect between connection points: r is an integer of at least 3; R is a hydrocarbon or siloxane-containing linking moiety; the composition includes a multiplicity of A units and multiplicity of B units; and a portion of the connection points are necessarily terminated by endcapping groups, wherein at least a portion of the endcapping groups are selected from the following structures: The invention also includes methods for making and using the above-described elastic composition.
