Hierarchical assembly of self-healing adhesive proteins creates strong and robust structural and interfacial materials, but understanding of the molecular design and structure-property relationships of structural proteins remains unclear. Elucidating this relationship would allow rational design of next generation genetically engineered self-healing structural proteins. Here we report a general...

This thesis describes the science and technology of a new class of autonomic polymeric materials which mimic some of the functionalities of biological materials. Specifically, we demonstrate an autonomic self-healing polymer system which can heal damage in both coatings and bulk materials. The new self-healing system we developed greatly extends the capability of self-healing polymers by introd...

Smart Cyber-Physical Systems (CPSs) are autonomic systems capable of making decisions at runtime by themselves. These systems are complex in nature and typically operate in highly unpredictable and uncertain environments. One key autonomic capability of such systems is to recover from failures in an autonomic manner, referred to as self-healing. Due to the wide range of applications of smart CP...

Self-healing is a capacity observed in most biological systems in which the healing processes are autonomously triggered after the damage. Inspired by this natural behavior, researchers believed that a synthetic material possessing similar self-recovery capability could also be developed. Albeit various intrinsic self-healing systems have been developed over the past few decades, restriction on...

Sun has developed a new architecture for building and deploying systems and services capable of Predictive SelfHealing. Self-healing technology enables Sun systems and services to maximize availability in the face of software and hardware faults. It facilitates a simpler and more effective end-to-end experience for system administrators, reducing cost of ownership. The first self-healing featur...

Self-healing polymers composed of microencapsulated healing agents exhibit remarkable mechanical performance and regenerative ability, but are limited to autonomic repair of a single damage event in a given location. Self-healing is triggered by crack-induced rupture of the embedded capsules; thus, once a localized region is depleted of healing agent, further repair is precluded. Re-mendable po...

In this study autonomic self-healing of impact damage in composite materials is shown using a microencapsulated healing agent. The components for self-healing, urea–formaldehyde microcapsules containing dicyclopentadiene (DCPD) liquid healing agent and paraffin wax microspheres containing 10 wt% Grubbs’ catalyst, have been successfully incorporated in a woven S2-glass-reinforced epoxy composite...

ID No: 252 ABSTRACT It has been confirmed by some previous research that some types of fiber-reinforced cementitious composites (FRCCs) particularly using synthetic fibers (e.g. polyvinyl alcohol; PVA) has a great capability of self-healing of cracks. In this study, selfhealing capability of FRCCs with the effects of additives such as silica fume and excess PVA dosage were tested. Experimental ...

A cyanate ester/microcapsule system with low cure temperature and self-healing " Abstract: Microcapsules filled with epoxy resin were blended into cyanate ester resin to produce systems with low cure temperature and self-healing capacity. A 4,4′-diaminodiphenylsulfone (DDS) curing agent was adopted for the systems. The mechanical properties, thermal stability and self-healing ability of the sys...
