Surface functionalization of graphene oxide (GO) is one of the best ways to achieve homogeneous dispersions of GO within polymeric matrices and composites. Nonetheless, studies regarding how the level of GO functionalization affects the macroscopic properties of three-dimensional (3D) printed nanocomposites are still few. Furthermore, the bifunctionalization of GO with the NH 2 /NH 3 + groups to obtain improved thermomechanical macroscopic properties at ultralow loads has not been reported. In this paper, fast and straightforward surface bifunctionalization of GO with a controlled ratio of NH 2 /NH 3 + groups at low, medium, and high functionalization levels (AGOL, AGOM, and AGOH) in a one-step microwave-assisted synthesis is reported for the first time. The functionalization mechanism was disclosed, wherein three graft densities (G φ ) were obtained. A plateau of maximum functionalization (G φ = 4.9 μmol/m 2 = 2.9 molecules/nm 2 ) was reached, suggesting that full coverage of the GO surface is achievable. Also, an increase in the exfoliation of functionalized layers was obtained, ranging from d 002 = 8.6 Å up to d 002 = 15.8 Å. X-ray photoelectron spectroscopy (XPS) reveals the successful functionalization of GO, as well as an atomic relationship NH 2 /NH 3 + of about 50/50% in all functionalized samples. Stereolithographic (SLA) 3D-printed nanocomposites (AGOL/R, AGOM/R, and AGOH/R) were obtained using ultralow loads (0.01 wt %) of each bifunctionalized material. This ultralow amount was sufficient to enhance thermal stability (up to 4 °C) and a significant increase in the glass transition temperature (93 °C ≤ T g ≤ 120 °C). Interestingly, we found that low and medium grafting density promotes a ductile material (ε > 5%); meanwhile, a high graft density produces brittle materials. Also, we observe that the toughness can be tuned as a function of the graft density (AGOH: 24 MPa, AGOM: 342 MPa, AGOL: 562 MPa) at ultralow loadings. The 3D-printed nanocomposites using GO with low graft density (AGOL) increase their tensile strain by 90% in comparison with the control sample (without filler). Finally, the underlying mechanisms were discussed to explain the findings.

A Revision for the Different Reuses of Polyethylene Terephthalate (PET) Water Bottles

According to studies on global plastic manufacturing and the resulting pollution, plastic wastes have been identified as a serious environmental concern. The impact of plastic garbage on marine species, humans, and the environment is a source of public concern, necessitating the need to save ecosystems and the lives that depend on them. Polyethylene terephthalate (PET) water bottles have a significant carbon footprint and represent tremendous waste. In the United Arab Emirates (UAE), PET water bottles are widely utilized, with yearly consumption reaching 450 water bottles per person. This study aims to review the literature on using PET water bottles in the UAE. A systematic literature search was conducted on journal articles, peer-reviewed journal articles, etc., published in the last 12 months. The main aspects of this systematic literature review include information on how plastic wastes are managed in the UAE and worldwide. In addition, it discusses the public health effects caused by plastic wastes, how the consumers of plastic bottles responded to the environmental policies, and so on. The article selection criteria included studies related to plastic water bottles in the UAE, waste management, environmental consequences, etc. A total of 30 articles were selected by initial screening, and 20 met the selection criteria and were included in the final review. To establish the credibility of this research, we understood that it was necessary to survey the UAE population to see the best approach to deal with PET water bottles.
