“…The diffusion path of gas molecules in the films are thus lengthened, equivalent to making the films thicker. [ 8 ] As a matter of fact, the oxygen barrier properties of polymers are dependent on the diffusion process of gas molecules in the films. [ 9 ] The permeated gas molecules can stay in the free volume cavity for a long time after they enter into the films, and then they occasionally jump to an adjacent cavity, that is, diffuse through the films.…”

The relatively poor oxygen barrier properties of polyethylene terephthalate (PET) limit its high‐end use in flexible electronic substrates. In this work, the oxygen barrier properties of PET films are highly improved by biaxially stretching PET films containing oxygen scavengers. The “active” oxygen scavengers result in a higher crystallinity of biaxially stretched PET films, improving the “passive” barrier properties. Biaxial stretching processing increases the surface area of oxygen scavengers’ domain, which consumes the oxygen molecules more effectively, thus improving the “active” barrier properties. More importantly, the enhanced “passive” barrier path prolongs the residence time of oxygen molecules in the films, allowing the oxygen scavenges to have enough time to sufficiently react with oxygen molecules. As a result, the oxygen permeability coefficient of biaxially stretching PET films containing oxygen scavengers is as low as 14.5792 cc mil m−2 day−1 0.1 MPa−1, synergistically improved by a factor of 11.99 compared to pristine PET films.

“…The increase in the crystallization temperature of PETEPOSS nanocomposites is not only the role of POSS as a nucleating agent. Ju 34 et al pointed out that the surface-active compatibilizer is added to the polymer matrix, which is beneficial to further increase the crystallization rate. Therefore, zinc acetylacetonate not only promotes the reaction between PET and EPOSS, but also accelerates the crystallization kinetics.…”

In the present study, an investigation was conducted on the effects of polyhedral oligomeric silsesquioxane (POSS) on the mechanical, morphological, and thermal properties of PET-based nanocomposites. When the epoxy groups reacted with the PET end groups, the transesterification catalyst zinc acetylacetonate was introduced to facilitate the reaction between PET matrix and EPOSS. As clearly observed in the SEM image, 3 wt% POSS was added to PET matrix, the size of POSS particles was lower than 50 nm. As revealed from the

“…Nevertheless, this process requires ASR to contain a large amount of lead, zinc, and other metals and thus lacks universality. Moreover, it is well showed that domain size is the predominant factor to determine the performance of polymer blend or composites 16,17 . The extremely complex components of ASR are not only difficult to match the processing temperature and viscosity, but also the incompatibility between the components is greatly amplified in the multi‐component phase domain 18 .…”

With the booming of the abandoned cars, automobile shredding residual (ASR) increase sharply in recent years. ASRs contain complex components that are difficult to separate and recycle, causing serious environmental impacts. Herein, we report a new strategy for ASR recycling to prepare high value‐added rigid polyurethane foams (RPUFs) with excellent mechanical and thermal properties. Ultrafine ASR powder with homogeneous domain size and activated functional groups, added to the precursor of RPUFs as reinforcing fillers, was fabricated through solid‐state shear milling (S3M) technology. As a nucleating agent, ASR particles can participate in the foaming procedure of RPUFs, which decreased the cell size to ~0.2 mm. Owing to the strong interaction between the ASR and polyurethane matrix, the thermal degradation temperature increased to 246.7°C, 42.4°C higher than the neat one. Inspiringly, the ASR particles can act as reinforcing elements in the cell walls, which can not only increase the compressive strength and modulus to 1.79 and 0.1 MPa respectively, 81% and 71% higher than the neat sample, but also enhance the long‐term fatigue resistance of the foam. This strategy achieves the recycling and utilization of ASR, and expands the application scope of RPUFs as well.
