“…Recalling the degree of crystallinity predicted by the XRD measurements, a direct relationship can be established between the compressive strength of the composites and their crystalline structure. The developed UPR-PUD composites attained higher compressive strength than that of other UPR-based composites such as UPR-rubber [24] and UPR-date seed [32], and were comparable with the compressive strength of UPR-bauxite residue composite [25] and UPR-calcined kaolin clay [38], with an advantage for the current composites in that they have a lower density. Furthermore, the proposed UPR-PUD composites achieved greater compressive strength than several lightweight insulation materials, with a compressive strength ranging from 2.4 to 3.3 MPa [39], as well as mineral wool and sisal fiber-reinforced building materials, with a strength of 3-4.5 MPa [40].…”

The massive production of Polyurethane foam from various products generates an extensive amount of waste, mostly in the form of dust that is emitted while cutting, trimming, or grinding the foam. In this research, the polyurethane dust (PUD) waste is incorporated into unsaturated polyester resin (UPR) to fabricate a heat insulation composite material to be used in construction. Filler percentages ranging from 10% to 50% were used to make the UPR-PUD composite materials. The thermal and mechanical properties of the material were studied in order to evaluate the ability of the composites for this type of application. Thermogravimetric Analysis and Differential Scanning Calorimeter tests were applied to determine the thermal stability of the material. In addition, the microstructure of the prepared composites and the incorporation of PUD filler into the polyester matrix were investigated by Scanning Electron Microscopy, X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) analysis. The FTIR and XRD analyses suggested that adding PUD improved the curing process of unsaturated polyester and enhanced its crystalline structure. The experimental results showed promising thermal insulation capability, with low thermal conductivity in the range of 0.076 to 0.10 and low water retention. Moreover, the composites exhibited compression strength between 56 and 100 MPa and tensile strength between 10.3 and 28 MPa, much higher than traditional thermal insulators and many building materials.

“…Natural ATP as a traditional building material has been widely used in adsorbents, reinforcement, and dispersion matrix. − To combine ATP with its characteristics in building and decoration, we then designed a desktop by coating Fe-Cu/ATP with POD-like activity onto the surface of polyethylene (PE) via a simple hot-pressing method, which is denoted as Fe-Cu/ATP-PE. The composite desktop turned to brownish-red color due to the addition of Fe-Cu/ATP (Figure a).…”

The search for low-cost, highly efficient, and stable nanozymes mimicking peroxidase (POD) enzymes remains a great challenge in the development of valuable antibacterial applications. Herein, a natural attapulgite (ATP)-supported Fe and Cu oxide with mixed valences (Fe-Cu/ATP) is reported as an efficient nanozyme by a feasible impregnation method. The obtained Fe-Cu/ATP nanozyme with a large specific area and high dispersity can effectively catalyze the hydrogen peroxide (H 2 O 2 ) decomposition, exhibiting enhanced POD-like activity compared with Fe/ATP, Cu/ATP, and pristine ATP. In addition, the Fe-Cu/ATP showed high stability and reusability. Through further combination with the density functional theory calculation, the electron density of the ATP surface is increased by simultaneously introducing Fe and Cu dopants. Thus, Fe-Cu/ATP possesses excellent antibacterial properties including a short-time effect depending on the POD-like activity with H 2 O 2 and a long-term effect generated by the metal without H 2 O 2 . Finally, a coating desktop and an antibacterial fabric were delicately designed and fabricated by loading Fe-Cu/ATP onto polyethylene and a fabric surface, showing the enormous potential of Fe-Cu/ATP as building and medical functional coatings. This study provides a rational way to design natural mineral nanozymes for promising antibacterial applications.

Geopolymer Ceramic Application: A Review on Mix Design, Properties and Reinforcement Enhancement

et al. 2022

Geopolymers have been intensively explored over the past several decades and considered as green materials and may be synthesised from natural sources and wastes. Global attention has been generated by the use of kaolin and calcined kaolin in the production of ceramics, green cement, and concrete for the construction industry and composite materials. The previous findings on ceramic geopolymer mix design and factors affecting their suitability as green ceramics are reviewed. It has been found that kaolin offers significant benefit for ceramic geopolymer applications, including excellent chemical resistance, good mechanical properties, and good thermal properties that allow it to sinter at a low temperature, 200 °C. The review showed that ceramic geopolymers can be made from kaolin with a low calcination temperature that have similar properties to those made from high calcined temperature. However, the choice of alkali activator and chemical composition should be carefully investigated, especially under normal curing conditions, 27 °C. A comprehensive review of the properties of kaolin ceramic geopolymers is also presented, including compressive strength, chemical composition, morphological, and phase analysis. This review also highlights recent findings on the range of sintering temperature in the ceramic geopolymer field which should be performed between 600 °C and 1200 °C. A brief understanding of kaolin geopolymers with a few types of reinforcement towards property enhancement were covered. To improve toughness, the role of zirconia was highlighted. The addition of zirconia between 10% and 40% in geopolymer materials promises better properties and the mechanism reaction is presented. Findings from the review should be used to identify potential strategies that could develop the performance of the kaolin ceramic geopolymers industry in the electronics industry, cement, and biomedical materials.
