“…However, a small amount of work has already been done on turning polyimides into self-healing grades. Nevertheless, these efforts have not been very successful so far and resulted in polymers with low mechanical properties or needing heating to induce healing (13)(14)(15)(16).…”

Traditional polyetherimides (PEIs) are commonly synthesized from an aromatic diamine and an aromatic dianhydride (e.g. 3,4'-oxydianiline (ODA) and 4,4'-oxydiphtalic anhydride (ODPA)) leading to the imide linkage and outstanding chemical, thermal and mechanical properties yet lacking any self-healing functionality. In this work, we have replaced the traditional aromatic diamine by a branched aliphatic fatty dimer diamine (DD1).This led to a whole family of self-healing polymers not containing reversible chemical bonds, capable of healing at (near) room temperature yet maintaining very high elastomeric-like mechanical properties (up to 6 MPa stress and 570% strain at break). In this work, we present the effect of the DD1/ODPA ratio on the general performance and healing behavior of a room temperature healing polyetherimide. A dedicated analysis suggests that healing proceeds in three steps: (i) an initial adhesive step leading to the formation of a relatively weak interface; (ii) a second step at long healing times leading to the formation of an interphase with different properties than the bulk material and (iii) disappearance of the damaged zone leading to full healing. We argue that the fast interfacial adhesive step is due to van der Waals interactions of long dangling alkyl chains followed by an interphase formation due to polymer chain interdiffusion. An increase in DD1 ratio leads to an increase in the healing kinetics and displacement shift of the first healing step towards lower temperatures. An excess of DD1 leads to the crosslinking of the polymer thereby restricting the necessary mobility for the interphase formation and limiting the self-healing behavior. The results here presented offer a new route for the development of room temperature self-healing thermoplastic elastomers with improved mechanical properties using fatty dimer diamines.

Self-healing polymers have the capability to autonomically heal themselves. Recent breakthroughs in self-healing systems rely on integrating nanoparticles into relevant polymers. This article overviews the self-healing performance of polymer/carbon nanotube nanocomposite. Self-healing carbon nanotube nanocomposites have been designed using epoxy, polyurethane, poly(methyl methacrylate), and rubbers. Great versatility of self-healed polymer/carbon nanotube depends on matrix modification, nanotube functionality, processing strategies, and matrix-nanofiller interaction/compatibility. Special consideration is given to self-healing efficiency of nanocomposites in technical fields, such as coatings, sensors, electronics, radiation shielding, drug delivery, and tissue engineering. Moreover, critical issues and challenges associated with self-healing nanocomposites are considered.

“…[1][2][3][4][5] Therefore, PIs have been widely applied in the fields of the aerospace, microelectronics, functional membranes and composites, and so on. [6][7][8][9] However, most of the aromatic PIs have high melting or glass transition temperatures (T g s), low optical transparency, and limited solubility in most organic solvents because of their rigid backbones and strong intermolecular interactions, which may restrict their applications in some fields. Meanwhile, the vigorous development of these high-tech fields has imposed increasingly stringent requirements on the polymer materials employed in these fields.…”

Two new isomers containing pyridine ring diamine monomers, 2,2 0 -bis[4-(5-amino-2-pyridinoxy)phenyl] propane (1b) and 2,2 0 -bis[4-(6-amino-3-pyridinoxy)phenyl] propane (2b), were prepared via a simple nucleophilic reaction of 2-chloro-5-nitropyridine and 5-bromo-2-nitropyridine with bisphenol A in the presence of potassium carbonate, respectively. A series of polyimides (PIs) were obtained from the heterocyclic diamine with various commercially available aromatic dianhydrides via the conventional two-step method. These obtained PIs were investigated in aspects of their solubility, thermal, mechanical, and optical properties for studying the effects of the heteroaromatic rings into the main chain. At the same time, the impact of the two isomers introduced into the PI was discussed in detail.
