High Modulus Epoxy/GO-PANI Self-Healing Materials Without Catalyst by Molecular Engineering and Nanocomposite Fabrication.

Nowadays, self-healing materials have been studied actively in electronics, soft robotics, aerospace, and automobiles because they can prolong the life span of the materials. However, overcoming the trade-off relationship between mechanical properties and self-healing performance is challenging. Herein, graphene oxide-polyaniline (GO-PANI) filler was introduced to overcome this challenge because GO has a highly excellent modulus, and nitrogen atoms in PANI can endow a self-healing ability through hydrogen bonds.

Epoxy-Based Catalyst-Free Self-Healing Elastomers at Room Temperature Employing Aromatic Disulfide and Hydrogen Bonds.

In this paper, catalyst-free room-temperature healing epoxy vitrimer-like materials (S-vitrimer) are introduced. The S-vitrimer can be healed at room temperature without any external stimuli such as solvent, pressure, heat, and catalyst through an aromatic disulfide exchange reaction and a hydrogen bond because the glass transition temperature of the S-vitrimer is lower than room temperature. Self-healing materials are attracting widespread attention nowadays with their potential to increase the durability of the materials.

CNT-Reinforced Self-Healable Epoxy Dynamic Networks Based on Disulfide Bond Exchange.

The design and utilization of polymers with healing capability have drawn increasing attention owing to their enhanced chain mobility and opportunity to heal minor cracks in composites. Rehealable thermoset polymers promise reduction in the maintenance cost and thus prolonged lifetime, reshaping, and recyclability. Introducing reversible covalent bonds is the mainstay strategy to achieve such plasticity in crosslinked polymers.

Methods: In this study, 30 patients with anxiety disorders according to criteria specified in Diagnostic and Statistical Manual of Mental Disorders, 4. Edition (DSM-IV) were assigned to sertraline treatment.

Effectiveness of systemic treatment agents on psoriatic nails: a comparative study.

Background: Nails, one of the most visible sites of body, are frequently involved in psoriasis and accepted as the most difficult site for topical treatment because of their anatomical structure. Healing of the psoriatic nails usually occurs when systemic therapy is initiated to treat severe skin psoriasis or joint involvement, but sometimes systemic therapy is essential for severe nail psoriasis, although Psoriasis Area and Severity Index (PASI) score is low or none of the joints are affected. In this case, knowing which systemic agent is most potent on nail findings is important.
