A Clean and Sustainable Cellulose‐Based Composite Film Reinforced with Waste Plastic Polyethylene Terephthalate

Abstract

With the widespread use and increasing consumption of PET, the amount of waste PET is growing rapidly, and the accompanied environmental problems will become more and more serious. Therefore, the recycling and reuse of PET are of great significance for not only saving resources but also solving environmental issues. In this study, Methylcellulose (MC) composites reinforced with waste plastics polyethylene terephthalate (PET) were prepared by casting an MC/PET solution with a varying mass ratio of MC to PET. Systematic investigations were performed to reveal the effect of the MC/PET mass ratio on the mechanical property, chemical structure, and thermal properties. The resultant findings indicate that the addition of 3% waste plastics PET to MC could notably enhance the tensile strength by about 24% as compared with neat MC. Interestingly, the elongation of the MC/PET composite kept increasing with increasing waste plastics PET. At the same time, thermal compression treatment could also enhance the mechanical properties of the composite. Moreover, the composites also displayed higher thermal stability than MC. In addition, the crystallinity and morphology of the composite were estimated by XRD and SEM.

Eco-Friendly High-Performance Poly(methyl methacrylate) Film Reinforced with Methylcellulose

“…Figure gives the XRD patterns of selected samples. MC displays two characteristic diffractions of the semicrystalline structure at 2θ = 8.9 and 19.7°. ,− PMMA exhibits an amorphous structure with two broad diffraction peaks at around 2θ values of 15 and 30°. , In the XRD patterns of the PMMA/MC films, the diffraction signal for MC at 8.9° is absent, and the intensity of the diffraction signal at 19.7° is decreased. At the same time, the intensity of the diffraction signal at 19.7° for MC becomes weaker with an increase in the amount of PMMA in proportion to MC.…”

Conversion of Plastic Waste into Supports for Nanostructured Heterogeneous Catalysts: Application in Environmental Remediation

“…The authors showed that ultra-fine PET nanofibers were successfully manufactured from plastic bottles for application as face masks or air filters [270]. The use of PET waste in adequate proportions to obtain composites can improve some properties [271]. Recently, Aydogmus et al [272], produced a biocomposite reinforced with polyethylene terephthalate waste, and it was observed that the behavior of the biocomposite at high temperatures improved with increasing PET waste content.…”

A Review on the Modification of Cellulose and Its Applications

“…Sustainability necessitates the advancement of human science and technology, as well as a greater demand for trees, [ 12 , 13 , 14 ] plants, some marine organisms, and algae having a fundamental reinforcing property that enhances all subsequent constructions. The bulk of the hierarchical structure is eliminated by extracting cellulose at the nanoscale, and a new cellulose-based “building block” is available as composites [ 15 , 16 ].…”
