Polymer‐based nanocomposites can be used in a wide variety of applications in the industrial, electronics, and energy segments. In order to attain the application‐specific properties that are desired, good mechanical and fracture efficiency is frequently required. Polyamide 6 (PA6)/polyethylene octene grafted with maleic anhydride (POE‐g‐MA)/titanium dioxide (TiO2) nanocomposites' fracture characteristics were investigated utilizing the essential work of fracture (EWF) approach in this work. Four levels of POE‐g‐MA (0, 10, 20, and 30 wt%) and three levels of TiO2 (0, 2, and 4 wt%) are therefore utilized. The reliability of the EWF theory is demonstrated via the self‐similarity of the force‐displacement curve and Hill's analysis. Results showed that EWF and non‐essential work of fracture (non‐EWF) were improved by 73% and 54%, respectively, by increasing POE‐g‐MA up to 30 wt%. The improvement of EWF value confirmed the role of POE‐g‐MA as an impact modifier. Nevertheless, by increasing TiO2 up to 4 wt%, EWF, and non‐EWF decrease by 20% and 25%, respectively. Adding 30 wt% POE‐g‐MA reduced tensile strength and enhanced strain at the break by 45% and 109%, respectively. Moreover, the tensile strength was enhanced up to 10% by adding 4 wt% of TiO2 content. However, the strain at break was decreased by 44% by increasing 4 wt% of TiO2 nanoparticle. In addition, the dominant fracture mechanism in polyamide‐based blends and nanocomposites is shear‐yielding and fibrillation structures.

“…So, we believed that the miscibility between POE‐g‐MAH and PA6 was better than that of POE‐g‐MAH and rCOC due to the good interaction between the amino groups in PA6 and the carboxyl groups in POE‐g‐MAH. [ 27–29 ]…”

“…So, we believed that the miscibility between POE-g-MAH and PA6 was better than that of POE-g-MAH and rCOC due to the good interaction between the amino groups in PA6 and the carboxyl groups in POE-g-MAH. [27][28][29] Meanwhile, it was found that the introduction of the elastic phase (POE-g-MAH) decreased the storage modulus of its blends. Because the mechanical strength of POE-g-MAH was much lower than that of PA6 and rCOC, the storage modulus of the blend dropped a little.…”

At present, it is of great significance to develop an effective method of recycling cyclic olefin copolymers (rCOC) due to its increasing application. But, its poor toughness is still an important difficulty to limit its effective recycling. In this article, we introduced PA6 into the POE-g-MAH/rCOC composites. Because of the good compatibility of POE-g-MAH between PA6 and rCOC, it just led to an overall improvement in mechanical properties of PA6/POE-g-MAH/rCOC (45/15/40) composites. Its tensile strength reached 42.3 MPa, which was more than 41.9% compared with that of POE-g-MAH/rCOC composites. Its notched impact strength was 11.7 kJ/m 2 , which was higher than 875.0% compared with rCOC. Furthermore, the component of PA6 was wrapped by nonpolar rCOC and POE-g-MAH, resulting in a low water absorption rate (1.0%). So, the strength of the composites only dropped a little after water adsorption. In summary, the addition of PA6 helped the composites effectively utilize the toughness of POE-g-MAH. Thus, we developed an easy method to recycle rCOC and prepare the responding composites with high strength and toughness.compatibility, PA6, POE-g-MAH, recycled cycloolefin copolymer, toughening | INTRODUCTIONCyclic olefin copolymers (COCs) are amorphous transparent material prepared by metallocene polymerization with norbornene or its derivatives and ethylene. [1][2][3][4][5] Compared with traditional transparency plastics such as polycarbonate (PC) and polymethyl methacrylate (PMMA), COC resin has been widely used in high-end lenses, medical equipment, [6] and pharmaceutical packaging [7] due to its high water vapor barrier rate, [8,9] good chemical resistance, [10] and high biocompatibility. [11] But, due to the high requirements for materials in the optical field and pharmaceutical field, recycled COC resin is not permitted to employ again. Thus, the recycling of this stable COC resin becomes more and more urgent. However, the poor toughness of rCOC has greatly limited

Composites with good thermomechanical and UV‐shielding properties are essential in fiber‐reinforced composites. This paper focuses on composites' ultraviolet (UV) shielding efficiency with added Ce‐Zr‐Si oxide nanoparticles/epoxy resin. The Ce‐Zr oxide nanoparticles were first functionalized with a silicon coupling agent and ethyl silicate to improve their dispersion and surface activity. In this work, we prepared epoxy nanocomposites with the addition of Ce‐Zr ‐Si oxides(1,3,5,7 wt%) and found that the materials had good enhancement of the UV shielding properties of the epoxy resin matrix. Meanwhile, it was used in basalt fiber (BF)/epoxy composites prepared by the hot‐pressing method, and surface treatment of basalt fibers was carried out. The results showed that the modified fiber composites could effectively enhance the thermomechanical properties of epoxy resin composites. It is noteworthy that the tensile strength and flexural strength of the hybrid composites reached their peak when 5 wt% Ce‐Zr‐Si was added, increasing by 13.8% and 33.67% respectively. The modified (BF)/epoxy composites exhibited improved thermal stability compared to pure epoxy resin, with the maximum weight loss temperature of BF‐1/EP reaching 349°C. The T(UVA) decreased to 2.41%, while the T(UVB) decreased to 0.053%, and almost all the ultraviolet irradiation was blocked. These results show that our prepared composites have good thermomechanical and UV shielding properties.Highlights Ce‐Zr oxide nanoparticles were functionalized with a silicon coupling agent. Ce‐Zr‐Si oxide was added to enhance the ultraviolet shielding efficiency. Modified BFs were composited to improve thermomechanical properties.
