“…In fact, various fillers of different geometries are widely used for rubber modification, [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] such as talc, [15] carbon black, [23] silica, [26,27] montmorillonite, [24,25] vermiculite, [17] mica, [16] sepiolite, [18,19] and, recently, halloysite. [20][21][22] However, most of the studies are focused on the mechanical properties of the systems, on their structure, thermal stability, and permeability, but there are quite a few papers on adhesion properties of non-cross-linked adhesives with nanofillers.…”

Two nanosized fillers (fumed silica Rosil-175 up to 20 wt% and halloysite nanotubes up to 40 wt%) were used to suppress cold flow of polyisobutylene (PIB)-based adhesives. Rheological measurements revealed the presence of the yield stress in the PIB-halloysite system which is indicative of the three-dimensional network formation in the bulk of the matrix. However, further rheology tests identified low strength of the network. In case of Rosil, no yield stress was detected, only gradual increase in the viscosity. Shear bank testing showed 4-5 times increase in the PIB-halloysite system time to failure when 40 wt% of halloysite was incorporated into the PIB matrix. Increase in the time to failure for PIB-Rosil systems was over two orders of magnitude -at the Rosil content up to 20 wt%. Such superior properties of the Rosil adhesion joints are considered to be the result of Rosil high specific area and low strength of the halloysite nanotubes network.

Nanocomposites of chlorinated polyethylene/ethylene methacrylate copolymer (60/40 ratio) with augmented polymer–filler interface adhesion were prepared by following a facile covalent modification of halloysite nanotubes (HNTs). The covalent modification of the outer and inner lumen structures of HNTs were pursued by two different methods: in-situ ring opening polymerization of ε-caprolactone and silane modification using organosilane (3-aminopropyl)triethoxysilane. Fourier transform infrared spectroscopy, X-ray diffreaction, high-resolution transmission electron microscopy, and water contact angle measurement manifests a successful organic covalent modification of the HNT surface. The synergistic mechanical properties of covalently poly(ε-caprolactone)-modified HNT nanocomposites come from the ameliorated polymer–filler interface interaction that can be understood by the study of the “Pukánszky model” and dynamic mechanical analysis. The rheology study of nanocomposites help understand the polymer–filler interaction. Good polymer–filler adhesion leads to a better state of filler dispersion in the polymer matrix as evident from the “effective free-space length (L f*)” of the transmission electron microscopy analysis, wide-angle X-ray diffraction, field emission scanning electron microscopy, and atomic force microscopy study of the nanocomposites.

“…As shown in Figure 5a, the characteristic peaks of O 1s, Si 2p/2s, and Al 2p/2s were all observed in these two samples, which were attributed to the elements O, Si, and Al in HNTs. In the case of unmodified P-HNTs, carbon impurity (C 1s peak) was detected on the nanoclay surfaces as shown in Figure S1, which could be assigned to the contamination of the oxide surface deriving from the atmosphere or in the wet process [48]. Excitingly, the signals of N appeared in the curve of PDA-HNTs, indicating that the PDA layer was successfully decorated on the HNTs surfaces.…”

Abstract:In this study, a novel and convenient bio-inspired modification strategy was used to create stable superhydrophobic structures on halloysite clay nanotubes (HNTs) surfaces. The polydopamine (PDA) nanoparticles can firmly adhere on HNTs surfaces in a mail environment of pH 8.5 via the oxidative self-polymerization of dopamine and synthesize a rough nano-layer assisted with vitamin M, which provides a catechol functional platform for the secondary reaction to graft hydrophobic long-chain alkylamine for preparation of hierarchical micro/nano structures with superhydrophobic properties. The micromorphology, crystal structure, and surface chemical composition of the resultant superhydrophobic HNTs were characterized by field emission scanning electron (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). The as-formed surfaces exhibited outstanding superhydrophobicity with a water contact angle (CA) of 156.3 ± 2.3 • , while having little effect on the crystal structures of HNTs. Meanwhile, the resultant HNTs also showed robust stability that can conquer various harsh conditions including strong acidic/alkaline solutions, organic solvents, water boiling, ultrasonic cleaning, and outdoor solar radiation. In addition, the novel HNTs exhibited excellent packaged capabilities of phase change materials (PCMs) for practical application in thermal energy storage, which improved the mass fractions by 22.94% for stearic acid and showed good recyclability. These HNTs also exhibited good oil/water separation ability. Consequently, due to the superior merits of high efficiency, easy operation, and non-toxicity, this bionic surface modification approach may make HNTs have great potentials for extensive applications.
