“…In addition, the high aspect ratio of PAL was also favorable to the stress transfer when the film was subject to be stretched. The similar results were observed in other PAL nanorod-reinforced polymers (Chen et al, 2012; Liu et al, 2014).…”

A series of biopolymer-based nanocomposite films were prepared by incorporating natural one-dimensional (1D) palygorskite (PAL) nanorods, and two-dimensional (2D) montmorillonite (MMT) nanoplatelets into sodium alginate (SA) film by a simple solution casting method. The effect of different dimensions of nanoclays on the mechanical, water resistance, and light transmission properties of the SA/PAL or MMT nanocomposite films were studied. The field-emission scanning electron microscopy (FE-SEM) result showed that PAL can disperse better than MMT in the SA matrix in the case of the same addition amount. The incorporation of both PAL and MMT into the SA film can enhance the tensile strength (TS) and water resistance capability of the film. At a high content of nanoclays, the SA/PAL nanocomposite film shows relatively higher TS, and better water resistance than the SA/MMT nanocomposite film. The SA/MMT nanocomposite films have better light transmission than SA/PAL nanocomposite film at the same loading amount of nanoclays. These results demonstrated that 1D PAL nanorods are more suitable candidate of inorganic filler to improve the mechanical and water resistance properties of biopolymers/nanoclays nanocomposites.

“…After introducing temperature-resistant inorganic substances into the polymer gel system, the performance of copolymer gels was significantly improved. Commonly used inorganic materials mainly include inorganic silicate [ 8 ], SiO 2 [ 9 , 10 , 11 ], kaolin [ 12 ], laponite [ 13 ], bentonite [ 14 ], sepiolite [ 15 ], attapulgite clay [ 16 ], copolymers with comonomers having precursor moieties to form silica crosslinkers by a sol-gel process [ 17 , 18 , 19 ], etc. [ 20 , 21 , 22 , 23 ].…”

In this study, a modified chemical plugging agent is prepared with the aim to reduce the well moisture content and improve the efficiency of oilfield development. In comparison to other chemical plugging agents, the composite gels plugging agents have excellent blocking capacity and erosion resistance. In this study, optimal conditions for the preparation of plugging agents were explored. The results showed that the performance of polyacrylamide-sericite (PAM-sericite) gel improved at a polymerization temperature of 60 °C, a crosslinker concentration of 0.5%, an initiator concentration of 0.75%, an acrylamide concentration of 10.0%, and a sericite concentration of 10.0%. The characterization of PAM-sericite gel showed a certain fold-like shape with a smoother surface, indicating that the doped sericite makes the plugging agent more compact and firm. It was also found that the blocking ratio of the plugging agent can potentially reach 99.5% after the addition of sericite. Moreover, failure stress of the skeleton structure and the water swelling degree were increased by 63.5% and 51.2%, respectively. Additionally, long-term stability, temperature resistance, pressure resistance and pressure stability also showed improvement to varying degrees. It was concluded that this gel has better stability against different kinds of salt solutions and is not affected by particle size.

“…To improve the dispersibility of the clay mineral nanomaterials in the polymer matrices and enhance the interfacial property of the resultant clay mineral/polymer nanocomposites through the physical blending approach, the clay mineral nanomaterials should be surface modified with the organic groups (Huskic et al, 2013;Carli et al, 2014;Ianchis et al, 2015) or polymers (Bi et al, 2014;Liu et al, 2014a;Sebenik et al, 2015).…”

“…For the purpose, the clay minerals should be modified with polymer chains and then the polymer grafted clay minerals are physically mixed with the desired polymer matrices. However, the polymer grafted clay minerals have to be separated from the free ungrafted polymer in both "grafting onto" (Bi et al, 2014;Sebenik et al, 2015) or "grafting from" (Jiang and Abe, 2015) methods, only when the surface-initiated controlled/"living" radical polymerization technique is utilized in the "grafting from" approach (Liu et al, 2014a). The tedious process restricts the practical application of the strategy or the mass industrial production.…”
