Structural and mechanical properties of flexible polyurethane foams cured under pressure

Flexible two-component polyurethane foam was synthesized under various extents of overpressure up to 2 bar. The influence of the pressure conditions on shrinkage and basic foam properties such as the

Restoration of Impact Damage in Polymers via a Hybrid Microcapsule–Microvascular Self‐Healing System

A hybrid microcapsule–microvascular system is introduced to regenerate the multiscale damage that results from impact puncture of vascularized polymeric sheets. Microvascular delivery of a two‐stage

Biological Archetypes for Self-Healing Materials

An overview of some paradigmatic and well-studied examples of self-repair in living systems is provided, including a number of case studies that provide a detailed description of the structure–function relationships defining the healing mechanism.

An Overview of Bioinspired and Biomimetic Self-Repairing Materials

The current overview presents a selection of breakthroughs regarding bioinspired or biomimetic self-repairing materials, including the initial basic publications and the recent publications of the last eight years.


After an artificial injury in succulent leaves of Delosperma cooperi and Delosperma ecklonis rapid wound sealing by deformation of the entire leaf takes place within approximately 90 minutes. On the

Biological Archetypes for Self-Healing Materials Matthew

Damage and fatigue are ever-present facts of life. Given enough time, even the most robust material, whether man-made or natural, succumbs to the deleterious effects of cracks, fissures, and defects

Biomechanics and Functional Morphology of Plants—Inspiration for Biomimetic Materials and Structures

During the last decades, biomimetics has attracted increasing attention as well from basic and applied research as from various fields of industry. Biomimetics has a high innovation potential and

Self‐Sealing and Puncture Resistant Breathable Membranes for Water‐Evaporation Applications

Breathable and waterproof membranes that self-seal damaged areas are prepared by modifying a poly(ether ester) membrane with an amphiphilic polymer co-network. The latter swells in water and the gel



Biomimetic self-healing of advanced composite structures using hollow glass fibres

The use of functional repair components stored inside hollow reinforcing fibres is being considered as a self-repair system for future composite structures. The incorporation of a self-healing

Parametric studies on self-repairing approaches for resin infused composites subjected to low velocity impact

Low velocity impact response of glass reinforced polymer composites, which have the potential to self-repair both micro- and macro-damage, has been investigated. This class of material falls under

Bioinspired engineering study of Plantae vascules for self-healing composite structures

The results clearly show that damage morphology is influenced by vascule orientation and that a 10 J low-velocity impact damage event is sufficient to breach the vasculature; a prerequisite for any subsequent self-healing function.

Autonomic healing of polymer composites

A structural polymeric material with the ability to autonomically heal cracks is reported, which incorporates a microencapsulated healing agent that is released upon crack intrusion and polymerization of the healing agent is triggered by contact with an embedded catalyst, bonding the crack faces.

In situ poly(urea-formaldehyde) microencapsulation of dicyclopentadiene

Urea-formaldehyde microcapsules containing dicyclopentadiene were prepared by in situ polymerization in an oil-in-water emulsion that meet these requirements for self-healing epoxy.

Self-healing materials with microvascular networks.

A self-healing system capable of autonomously repairing repeated damage events via a three-dimensional microvascular network embedded in the substrate is reported, opening new avenues for continuous delivery of healing agents for self-repair as well as other active species for additional functionality.

Tire with Self-Repairing Mechanism

A new type of tire is presented, in which there is no air leakage when nails puncture the tire. The broken part is repaired automatically by a self-repairing mechanism. The self-repairing unit

Microcapsule induced toughening in a self-healing polymer composite

Microencapsulated dicyclopentadiene (DCPD) healing agent and Grubbs' Ru catalyst are incorporated into an epoxy matrix to produce a polymer composite capable of self-healing. The fracture toughness
