“…Coextrusion is an industrial process widely used to form multilayered sheets or films that are suitable for various products, ranging from food packaging, the medical area, and recently in microelectronic and nonlinear optics with more than thousands of layers [66,67]. Multilayered polymer systems are produced to satisfy specific requirements for high valueadded applications such as gas barrier films [68,69], mechanical robust systems [70][71][72][73], and optical applications [74][75][76]. The coextrusion is a process which combines multiple polymers via two or three extruders using a feedblock system, where the polymers melted (from separate extruders) are brought together [77].…”

In a circular economy context with the dual problems of depletion of natural resources and the environmental impact of a growing volume of wastes, it is of great importance to focus on the recycling process of multilayered plastic films. This review is dedicated first to the general concepts and summary of plastic waste management in general, making emphasis on the multilayer films recycling process. Then, in the second part, the focus is dealing with multilayer films manufacturing process, including the most common materials used for agricultural applications, their processing, and the challenges of their recycling, recyclability, and reuse. Hitherto, some prospects are discussed from eco-design to mechanical or chemical recycling approaches.

“…Scratches involving delamination usually create irreversible damage in the coating system compared to surface fractures, which are relatively easy to repair [ 5 ]. Generally, the weak interface bonding performance of multilayer polymeric structures makes them more vulnerable to scratch-induced delamination [ 25 ]. Several in-depth studies noted that the scratch behavior of multilayer polymer systems depends on the interfacial properties to some extent [ 26 , 27 ].…”

“…Shu et al [ 33 ] studied the interfacial damage behavior of hard diamond-like carbon (DLC)/steel systems in sliding contacts using cohesive zone elements (CZEs). Xu et al [ 25 ] also simulated the delamination in alternating multilayer poly (methyl methacrylate) (PMMA)/polycarbonate (PC) materials during scratching based on CZEs. Nevertheless, the majority of research [ 31 , 32 , 33 ] on scratch-induced delamination has been concentrated on hard coatings.…”

Effects of Interlaminar Failure on the Scratch Damage of Automotive Coatings: Cohesive Zone Modeling

et al. 2023

Interlaminar failure caused by scratches is a common damage mode in automotive coatings and is considered the potential trigger for irreversible destruction, i.e., plowing. This work strives to numerically investigate the mechanisms responsible for the complex scratch behavior of an automotive coating system, considering the interfacial failure. A finite element model is developed by incorporating a large deformation cohesive zone model for scratch-induced debonding simulation, where the mass scaling technique is utilized to minimize computational burden while ensuring accuracy. The delamination phenomenon of the automotive coating is reproduced, and its effects on scratch damage behavior are analyzed. Accordingly, it is revealed that the interlaminar delamination would produce significant stress redistribution, which leads to brittle and ductile damage of the coating and consequently affects the formation of plowing. Eventually, parametric studies on the effects of interfacial properties are performed. They demonstrate that the shear strength and shear fracture energy dominate scratch-induced delamination.

“…The results showed a signi cant increase in the compressive strength of the newly obtained NCs in comparison with Ti-Mo-Cu alloys, which helped them to be appropriate for tissue engineering [7]. However, being susceptible to scratches and brittleness and showing low resistance to strong solvents in its pure state limit its usage in different applications [8][9][10]. Therefore, it must be combined with some llers such as mesoporous organic material (MOM)s and ordered mesoporous carbon (OMC) to compensate for its drawbacks.…”

Ordered mesoporous carbons have recently been given signi cant attention because of their unique hexagonal structure, tunable large pore volumes, high thermal stability, and high surface-to-volume ratio. In this research paper, for achieving the maximum compatibility between the FDU-15 and poly(methyl methacrylate) (PMMA), KH-550 was used as a modifying and coupling agent to facilitate the bond formations between the mesoporous carbon and PMMA with the help of ultrasonic irradiation. Nanocomposite (NC) lms were produced via the in-situ polymerization method aligned with various amounts of modi ed FDU-15. Sample characterizations were done by Field-emission scanning electron microscope (FE-SEM), low angle X-ray diffraction (LXRD), Fourier transform infrared spectroscopy, transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). The LXRD pattern proved that the modi cation process did not affect the hexagonal mesoporous structure of FDU-15. The PMMA-m-FDU 2 wt% showed the existence of some pores on its surface according to FE-SEM. The TEM image of the NC depicted a uniform dispersion of mesoporous carbon into the polymer matrix and also con rmed the hexagonal 2D structure of the mesopores. TGA data also con rmed that as the m-FDU-15 increases into the PMMA matrix, the higher thermal stability will achieve, and also the T d will increase to the higher temperatures.
