Title: Self-healing barrier films for vacuum insulation panels

Abstract

A self-healing vacuum insulation panel and a method of manufacture are provided. The vacuum insulation panel includes a self-healing, multi-layer barrier film including a separator between a curing agent and a curable resin. Upon damage to the separator, the curing agent penetrates the separator due to a pressure differential across the barrier film and reacts with the curable resin to seal any cuts or punctures. The curing agent and the curable resin can be selected to have long term stability and a short reaction time with no need for external stimuli. As a result, the multi-layer barrier film can retain the internal vacuum and maintain a desirably low thermal conductivity using low-cost, commercially available epoxies and curing agents.

This article presents the demonstration of a rapid self-healing system for barrier films of vacuum insulation panels (VIPs). The proposed self-healing films can improve the durability of VIPs by in-situ remediation of film defects. The self-healing concept has seen limited applications in buildings, and the current work is the first proposed application to VIPs. VIPs can attain an order-of-magnitude lower thermal conductivity than traditional foam and fibrous building insulations. The key to the ultra-low thermal conductivity of VIPs is an evacuated core that is fully-encapsulated within impermeable barrier films. Evacuation of the core eliminates the gas conductivity, which is themore » « less

Composite wellbore seal system with sensing and self-healing capabilities

Patent Taha, Mahmoud Reda; Stormont, John

The present invention provides a self-healing wellbore seal system comprising a casing, a fiber reinforced polymer layer, and layer of polymer cement. The layers are bonded together and configured to create a low permeable and ductile seal at discrete locations of the wellbore or along the wellbore. The polymer layer may be chemically bonded to the casing and inhibits the formation of a microannulus at the casing. The polymer layer may be an aramid fiber reinforced polymer, a fiber reinforced polymer layer, or a glass reinforced polymer layer.
