“…The former means that organic silicone is added to the PO su strate by itself or with other FRs without forming chemical bonds with PO matrix. T reactive type mainly refers to the preparation of new flame-retardant polymers by copo ymerizing with flame-retardant units and grafting or crosslinking with macromolecul [105][106][107]. However, compared with reactive type of organic silicones, much more r search has been conducted on the additive type to improve the flame-retardant propertie Therefore, the influence of additive-type silicone FRs on PO polymer is the focus of th section.…”

With the continuous advancements of urbanization, the demand for power cables is increasing to replace overhead lines for energy transmission and distribution. Due to undesirable scenarios, e.g., the short circuit or poor contact, the cables can cause fire. The cable sheath has a significant effect on fire expansion. Thus, it is of great significance to carry out research on flame-retardant modification for cable sheath material to prevent fire accidents. With the continuous environmental concern, polyolefin (PO) is expected to gradually replace polyvinyl chloride (PVC) for cable sheath material. Moreover, the halogen-free flame retardants (FRs), which are the focus of this paper, will replace the ones with halogen gradually. The halogen-free FRs used in PO cable sheath material can be divided into inorganic flame retardant, organic flame retardant, and intumescent flame retardant (IFR). However, most FRs will cause severe damage to the mechanical properties of the PO cable sheath material, mainly reflected in the elongation at break and tensile strength. Therefore, the cooperative modification of PO materials for flame retardancy and mechanical properties has become a research hotspot. For this review, about 240 works from the literature related to FRs used in PO materials were investigated. It is shown that the simultaneous improvement for flame retardancy and mechanical properties mainly focuses on surface treatment technology, nanotechnology, and the cooperative effect of multiple FRs. The principle is mainly to improve the compatibility of FRs with PO polymers and/or increase the efficiency of FRs.

“…1,2 The use of additives such as rubbers, thermoplastics, block co-polymers or inorganic and carbonaceous micro-and nano-scale particles to name some of the most common, have all been used extensively to improve fracture toughness with varying degrees of success. [3][4][5][6][7][8][9][10] However, a common theme of this nonreactive additive approach is that they all have some deleterious effect upon mechanical performance 11,12 and thermal properties. 7 Furthermore, the resultant micro-or nano-scale morphology often creates processing challenges due to increased viscosity or particle filtration during composite fabrication.…”

In this work, molecular fortifiers are added to a highly aromatic and rigid epoxy monomer bis(2,7 diglycidyl ether naphthalenediol) methane (NNE) possessing a very high glass transition temperature (Tg) when cured with 4,4′‐diaminodiphenyl sulfone (DDS) to explore their impact upon mechanical and thermal properties and reactivity. The molecular fortifiers used are the nonfunctional naphthalene (NAPH), the reactive diluent o‐cresyl glycidyl ether (CGE) and an adduct of dihydroxy naphthalene and CGE (molecular fortifier naphthalene, MFN), a variant on the partially reacted substructures approach. The fortifiers are found to affect NNE/DDS reactivity and increase processability depending upon their propensity to attach to the network either through hydrogen bonding or pi‐pi electron interactions. Thermal analysis shows that the fortifiers increased cure conversion although the Tgs of the networks were generally unaffected until higher levels of addition. The fortifiers reduce moisture ingress and suppress glassy state β relaxations while increasing modulus significantly. Although there is little improvement in toughness overall, some evidence for higher fracture toughness is observed for the MFN and NAPH modified networks. This work highlights the effectiveness of different molecular level fortifiers on improving properties, in particular the rigidity of highly crosslinked networks.

“…The endeavor in conductive polymer composites (CPCs), an important type of composites, [1][2][3][4][5][6][7][8] has never ceased over the last three decades because there is an increasing need for advanced functional materials such as electromagnetic shielding, antistatic, and sensing materials in our modern society. CPCs have many advantages such as low density, ease of processing, and easily controllable resistivity.…”

Ternary blends containing one major and two minor components are a common type of polymer blends, however, they have never been used to improve the electrical conductivity of polymer composites. Herein, polycarbonate (PC)/nylon‐poly(m‐xylene adipamide) (MXD6)/poly(ethylene terephthalate) (PET) (70/15/15) ternary blend is used to improve the conductivity of PC by forming sea‐island type interfacial carbon black (CB) networks. The phase change of PET from island to continuous structure, caused by the formation of CB networks at PET/MXD6 interface, is the key of success. The electrical percolation threshold of CB is much smaller than that in neat PC (only a ninth). Rheological investigation is carried out to confirm the formation of CB networks. The static mechanical properties of PC/MXD6/PET (70/15/15)‐2 vol% CB composite are evaluated by tensile testing, showing improved stiffness and strength, compared with the corresponding ternary blend, neat PC, and PC‐2 vol% CB composite.
