Abstract

A new type of epoxy-amine-borate (EAB) hybrid material is reported for control of penetrant solvent molecules into cross-linked polymer networks.

Highlights

  • Composites and adhesives made from epoxy resins are of huge commercial importance supplying a market predicted to be worth over $14.26 billion by 2024.1 Within the research field of epoxy thermoset polymers, the development of methods to control and prevent ingress of small molecules through these materials is critical in the development of new, more durable, high performance materials

  • The absorption of small molecules into cross-linked polymer networks is linked to physical properties such as freevolume and cross-link density where the relative penetrability of small molecules is related to their inherent molecular volume.[11,12]

  • This shows that the use of either triethylborate or triisopropylborate in the synthesis of an EAB hybrid material was highly effective at preventing penetrant solvent ingress into the resulting cross-linked polymer network
