A microcapsule-type self-healing protective coating with secondary crack preventing capability has been developed using a silanol-terminated polydimethylsiloxane (STP)/dibutyltin dilaurate (DD) healing agent. STP undergoes condensation reaction in the presence of DD to give a viscoelastic substance. STP- and DD-containing microcapsules were prepared by in-situ polymerization and interfacial pol...

Self-healing is receiving an increasing amount of worldwide interest as a method to autonomously address damage in materials. The incorporation of a self-healing capability within fibre-reinforced polymers has been investigated by a number of workers previously. The use of functional repair components stored inside hollow glass fibres (HGF) is one such bioinspired approach being considered. Thi...

With the growing complexity of parallel architectures, the probability of system failures grows, too. One approach to cope with this problem is the self-healing, one of the organic computing’s self-x features. Self-healing in this context means that computer clusters should detect and handle failures automatically. This paper presents a self-healing mechanism based on checkpointing, so that a c...

The paper addresses the methods of description of friction-induced self-healing at the interface between two solid bodies. A macroscopic description of self-healing is based on a Turing system for the transfer of matter that leads to self-organization at the interface in the case of an unstable state. A microscopic description deals with a kinetic model of the process and entropy production dur...

ID No : ACM-01 ABSTRACT In the last decade, an increasing attention has been given to the development of repairing capabilities in materials, with an emphasis in specific strategies that can promote self-healing, with or without external triggers. Self-healing has opened several new possibilities, especially in applications where long-term reliability is demanded and either maintenance or repla...

Structural Health Monitoring (SHM) and self-healing materials are both areas of current, ongoing scientific research toward intelligent, maintenance-free materials. SHM has developed techniques to detect, locate, characterize, and quantify damage in simple and complex structures. Simultaneously, self-healing materials have been developed with an intrinsic capability to mend themselves, restorin...

Natural organisms have a unique property not yet available in robotics, a self-healing (SH) ability. This powerful biological healing function has inspired chemists to impart similar properties to synthetic materials to create “self-healing materials”. Recent development in SH-polymers made us investigate the potential of using these materials in robotics, and more specifically in compliant act...

The role of the crystal morphology and dissolution kinetics of Grubbs’ catalyst on self-healing capability is examined. Self-healing polymers require complete coverage of the crack plane with polymerized healing agent for optimal recovery of mechanical integrity. Lack of catalyst leads to incomplete coverage, partial polymerization, and poor mechanical recovery. Catalyst availability is determi...

The present work demonstrates the synthesis and application of permanent magnetic Nd2Fe14B microparticle (NMP)-loaded graphitic inks for realizing rapidly self-healing inexpensive printed electrochemical devices. The incorporation of NMPs into the printable ink imparts impressive self-healing ability to the printed conducting trace, with rapid (~50 ms) recovery of repeated large (3 mm) damages ...
