“…This conferred to the HNTs/Rosin nanocomposites were innovative protocol for consolidating waterlogged archaeological woods. In addition, Giuseppe Cavallaro et al [63] used the nanocomposite to enhance the thermal and mechanical properties between HNTs and beeswax by direct blending. The experiments indicated that the HNTs were homogeneously dispersed and significantly reduced the thermal degradation of Rosin.…”

Halloysite nanotubes (HNTs) are natural occurring mineral clay nanotubes that have excellent application potential in different fields. However, HNTs are heterogeneous in size, surface charge, and formation of surfacial hydrogen bond, which lead to weak affinity and aggregation at a certain extent. It is very important to modify the HNTs' surface to expand its applications. In this review, the structural characteristics, performance, and the related applications of surface-modified HNTs are reviewed. We focus on the surface-modified variation of HNTs, the effects of surface modification on the materials and related applications in various regions. In addition, future prospects and the meaning of surface modification were also discussed in HNTs studies. This review provides a reference for the application of HNTs modifications in the field of new nanomaterials.

“…Moreover, they have biocompatibility [15] and show no toxicity in vivo [16] and in vitro [17]. These characteristics make HNTs excellent smart materials for the most diverse applications-for example: food packaging [18][19][20], drug delivery [21][22][23][24][25][26], environment remediation and wastewater treatment [27], cultural heritage [28][29][30][31][32], and additives for enhancing the performances of polymers [14,33].…”

Featured Application: The review is focused on the stabilization of nanotubular materials in solvent media. This aspect is a key starting point for any application of nanotube-based formulations for pharmaceutical and industrial applications.Abstract: Inorganic nanotubes are attracting the interest of many scientists and researchers, due to their excellent application potential in different fields. Among them, halloysite and imogolite, two naturally-occurring aluminosilicate mineral clays, as well as boron nitride nanotubes have gained attention for their proper shapes and features. Above all, it is important to reach highly stable dispersion in water or organic media, in order to exploit the features of this kind of nanoparticles and to expand their applications. This review is focused on the structural and morphological features, performances, and ratios of inorganic nanotubes, considering the main strategies to prepare homogeneous colloidal suspensions in various solvent media as special focus and crucial point for their uses as nanomaterials.

“…When individualized hydrophobic halloysite nanotubes (HNTs) [5] are mixed with polyvinyl alcohol (PVA), HNTs-PVA is characterized as a fully biodegradable nanocomposite [4] with enhanced mechanical properties. Nanotubes such as HNTs [6][7][8][9] or carbon nanotubes (CNTs) [10] are very effective with even small quantities of loading with polymers such as thermoplastic nanoparticles, which could result in significant changes in the physical and chemical properties. The thermoplastic polymers, such as PVA, are also biocompatible polymers that are widely used in industry for films, paper, and adhesive coating due to their attractive properties [11,12].…”

Surface Improvement of Halloysite Nanotubes

A novel development on halloysite-polyvinyl alcohol (HNTs-PVA) nanocomposites has been conducted using malonic acid (MA) by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (XRD)-2θ-peak, suggesting that MA has no or little influence on the crystallographic structure of the HNTs-PVA. Images taken by field emission scanning electron microscope (FESEM) suggest possible effects of MA on the morphology and internal features of HNTs-PVA by reducing the agglomeration of HNTs, which is considered a decisive step in improving the surface qualities of HNTs. Investigating the samples using the Brunauer-Emmelt-Teller (BET) technique showed that the surface area was increased by about 10 times, reaching the second highest recorded results compared to the HNTs, which could be considered a breakthrough step in enhancing the properties of HNTs-PVA due to MA crosslinking.
