“…Moreover, POSS promotes flame retardancy (Bourbigot et al , 2009; Kim et al , 2014; Michalowski & Pielichowski, 2018; Kavuncuoglu et al , 2019;), self-healing (Diao et al , 2015; Behera et al , 2018), scratch protection (Lai et al , 2009; Ghermezcheshme et al , 2015; Hebda & Pielichowski, 2018), thermal shielding (Kannana et al , 2006; Janowski & Pielichowski, 2008; Spoljaric & Shanks, 2012; Carmo et al , 2014; Liu et al , 2015; Pagacz et al , 2018; Szolyga et al , 2018; Zaharescu et al , 2018), hydrogel formation (Mather et al , 2006; Wu et al , 2010), drug-releasing stent coatings (Guo et al , 2009; Huitron-Rattinger et al , 2013) and thin-film applications (Oaten & Choudhury, 2005; Madbouly & Otaigbe, 2009; Blattmann & Mulhaupt, 2016) as it was incorporated in polyurethane networks. Recent advancements in HNT-polyurethane systems have also been postulated in several studies and reviews in which the polyurethane matrix was given specific properties including: shape memory (Bouaziz et al , 2019), corrosion resistance in protective coatings (Zahidah et al , 2017; Zeng et al , 2019), drug delivery (Hanif et al , 2016; Fizir et al , 2018), removal of pollutants from water (Anastopoulos et al , 2018; Papoulis, 2019) and thermal stability + fire-proofing (Tang et al , 2008; Smith et al , 2018).…”

Thermoplastic polyurethane (TPU) matrix was reinforced with polyhedral oligomeric silsesquioxane (POSS) and halloysite nanotubes (HNT), both separately and combined. Composite samples were fabricated using a melt-compounding method. Characterization of the composites obtained was performed via tensile and hardness tests, melt-flow index measurements (MFI), abrasion tests, dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM) to investigate the mechanical performance, flow behaviour, tribological characteristics, thermo-mechanical response and morphological properties. The greatest tensile strength value was obtained for the smallest HNT content. Further addition of HNT resulted in agglomerations for both POSS and HNT particles. The shore hardness of TPU was enhanced by filler inclusions. The TPU/POSS composites displayed significant improvement in terms of abrasion resistance compared to TPU at lower loading levels. The DMA study showed that composites containing 0.5% POSS and 1.0% HNT displayed the greatest storage modulus. The glass-transition temperature of TPU shifted to smaller values with the addition of both nanoparticles. The HNT inclusions increased the MFI value of TPU because of their large aspect ratio. Homogeneous mixing of nanoparticles in the TPU matrix was confirmed by a SEM study of the composites. Their dispersion decreased as the concentrations of POSS and HNT increased. An adjuvant effect of POSS with HNT was achieved in their hybrid composites.

“…ZnO-based nanocomposites for environmental applications are becoming increasingly popular. The most diverse composites are synthesized based on it, where both natural substances (clay minerals, chitin, and chitosan) and artificial ones (graphene, CNT, polymers, and other metal oxides) are used as a matrix [305,306].…”

The features of the properties and creation of nanocomposite metal oxide materials, especially TiO2, ZnO, SnO2, ZrO2, and Fe3O4, and their applications for ecology are considered in the article. It is shown that nanomaterials based on them are very promising for use in the ecological direction, especially as sorbents, photocatalysts, and sensitive layers of gas sensors. The crystallochemical characteristics, surface structure, and surface phenomena that occur when they enter the water and air environment are given for these metal oxides, and it is shown that they play a significant role in obtaining the sorption and catalytic characteristics of these nanomaterials. Particular attention is paid to the dispersion and morphology of metal oxide particles by which their physical and chemical properties can be controlled. Synthesis methods of metal oxide nanomaterials and ways for creating of nanocomposites based on them are characterized, and it is noted that there are many methods for obtaining individual nanoparticles of metal oxides with certain properties. The main task is the correct selection and testing of parameters. The prospects for the production of metal oxide nanocomposites and their application for environmental applications are noted, which will lead to a fundamentally new class of materials and new environmental technologies with their participation.

“…Halloysite can be used as a natural microporous nanotube to increase the ability of PPy for loading the metal nanoparticles [21]. In addition to its microporous property, it has high thermal and mechanical stability, green character, and low toxicity structure [22]. Halloysite for its low‐cost property can be used as an alternative of carbon nanotubes (CNTs).…”
