“…A negative interaction energy corresponds to attraction, and the lower the interaction energy, the stronger the attraction. [ 35 ] As shown in Figure 5, the E interaction of model II for plasticized PVC composite incorporated with both TiO 2 @ZnAlSn and PETMP is −68 024 kcal mol −1 , which is lower than that of model I for plasticized PVC composites incorporated with only TiO 2 @ZnAlSn (−67 266 kcal mol −1 ). Thus, it is concluded that incorporation of PETMP can strengthen the interaction between the surface of TiO 2 @ZnAlSn and the PVC‐based matrix, which is possibly due to the strong interactions between “C–Cl” groups in PVC and “–SH” groups in the healing agent.…”

“…Then, the layer builder was used to form a PVC‐based matrix over the surface, and its interfacial interaction with TiO 2 @ZnAlSn was analyzed. The interfacial interaction was obtained from the following equation [ 35 ] :

E_{interaction} goodbreak= E_{total} goodbreak- ((), E_{LDH} goodbreak+ E_{matrix}),

where E total is the surface energy of LDH with PVC‐based matrix, E LDH is the surface energy of LDH without PVC‐based matrix, and E matrix is the energy of the PVC‐based matrix without LDH surface.…”

A high content of plasticizers in the polyvinyl chloride (PVC) matrix can affect the mechanical property and flame retardancy of the matrix, and it is challenging to prepare multifunctional additives for plasticized PVC composites. In this study, ternary‐layered double hydroxides loaded with titanium dioxide (TiO2@ZnAlSn) and pentaerythritol tetra‐(mercaptopropionate) (PETMP) were incorporated into plasticized PVC composites and their effects on the mechanical property, thermal stability, flame retardancy and smoke suppression were experimentally and theoretically investigated. The best tensile properties are achieved in the composite with 2 phr TiO2@ZnAlSn and 1.6 phr PETMP. Dynamic mechanical analysis (DMA) and molecular dynamics simulation indicate that TiO2@ZnAlSn and PETMP can enhance the interaction of plasticized PVC composite, and cone calorimeter test shows that they can reduce the total heat release (27.5%) and total smoke production (53.0%) of plasticized PVC composite. The flame‐retardant mechanism is deduced according to the results of scanning electron microscopy (SEM), Raman spectroscopy and pyrolysis/gas chromatography–mass spectrometry (Py/GC–MS). This study provides a novel thermal stabilizer that can improve the mechanical property, flame retardancy and smoke suppression of plasticized PVC composites.

“…In this regard, our research group has conducted in-depth research. Zhang et al − used the CVD method to grow the CNT layer in situ on the surface of FN and then loaded TS-1 nanoparticles by the hydrothermal method. TS-1 nanoparticles are highly dispersed in the prepared support (CNTs@FN) and contain a large amount of skeleton titanium, which shows extremely high activity and stability in propylene epoxidation reaction and also avoids the problem of separation of catalyst and product after reaction.…”

Polymer reaction and performance improvement are one of the important contents in the field of polymer materials science and engineering, in which polymer catalytic hydrogenation is an important part of polymer reaction. We reviewed the research achievements on polymer hydrogenation over the past 70 years and studied the mechanism of the hydrogenation reaction from the aspects of performance changes before and after polymer hydrogenation, the catalyst preparation/structure−activity relationship, and polymer hydrogenation kinetics. We pointed out the difficulty in separation and unsatisfactory high-temperature adaptability of traditional homogeneous catalysts and first proposed four effects affecting traditional heterogeneous polymer hydrogenation: scale effect, conformation effect, viscosity effect, and adhesion effect. Based on the structure−activity relationship of polymers, we put forward the application direction of hydrogenated polymers at present. We found that using a new kind of nanometal catalyst (Pd/CNTs@FN) as hydrogenation catalyst can effectively reduce or eliminate the negative effects of these four effects on the polymer hydrogenation reaction, and it is easy to separate from the reaction system. The addition of CNTs can effectively increase the specific surface area of the catalyst and strengthen the interaction between reactants and catalyst. Subsequent research should focus on designing the multiscale structure and improving low-temperature activity of the catalyst, reducing process cost, and using green and efficient separation methods to eliminate adverse effects, create a green and efficient polymer reaction system, accelerate the industrialization of polymer hydrogenation process, and provide theoretical guidance for the research and development of new polymer materials.
