“…Pal has good compatibility with polymer matrices after suitable surface treatments [ 25 , 26 , 27 ]. Pal has been widely used as the polymer enforcement dispersed in polymer matrices [ 28 ]. Chen et al [ 27 ] reported that Pal can significantly reinforce the mechanical properties and thermal stability of PMMA after its surface has been treated with an organic reagent.…”

Gel polymer electrolyte (GPE) is widely considered as a promising safe lithium-ion battery material compared to conventional organic liquid electrolyte, which is linked to a greater risk of corrosive liquid leakage, spontaneous combustion, and explosion. GPE contains polymers, lithium salts, and liquid electrolyte, and inorganic nanoparticles are often used as fillers to improve electrochemical performance. However, such composite polymer electrolytes are usually prepared by means of blending, which can impact on the compatibility between the polymer and filler. In this study, the hybrid copolymer poly (organic palygorskite-co-methyl methacrylate) (poly(OPal-MMA)) is synthesized using organic palygorskite (OPal) and MMA as raw materials. The poly(OPal-MMA) gel electrolyte exhibits an ionic conductivity of 2.94 × 10−3 S/cm at 30 °C. The Li/poly(OPal-MMA) electrolyte/LiFePO4 cell shows a wide electrochemical window (approximately 4.7 V), high discharge capacity (146.36 mAh/g), and a low capacity-decay rate (0.02%/cycle).

“…The characteristic spacings of M-ATP do not change significantly compared to those of ATP. This shows that the crystal structure of M-ATP remains unchanged and the surfactant is only bound to the surface of ATP, without inserting into the nanochannels of the ATP [14,28]. This is similar to the results of Li [11], who used CTAB to modify natural sepiolite and found that the crystal structures of CTAB-modified sepiolite were identical to those As can be seen in Figure 7, the spectra in both a and b showed the characteristic diffraction peaks of the samples at 2θ = 8.4, 29.8, 26.6 and 35.3; these correspond to the (110), (040), (400) and (440) crystal faces of attapulgite, respectively [27].…”

Synthesis of Castor Oil-Based Quaternary Ammonium Salt and Modification of Attapulgite for Treating Industrial Wastewaters

et al. 2023

In order to develop multifunctional quaternary ammonium salts and explore their advantages as modifiers for wastewater treatment, castor oil-based quaternary ammonium salts were synthesised and subsequently used as modifiers for attapulgite treatment. The structures of untreated and treated attapulgite were compared by Fourier transform infrared spectra and X-ray diffraction. The mechanism of modification was speculated. Various factors such as the amount of modified attapulgite, temperature and pH were also investigated in the batch experiments on the removal rates of acetone and phenol from wastewaters. The synthesis conditions were set as follows: the reaction temperature was 80 °C, the reaction time was 8 h, the molar ratio of castor oil to N,N-dimethyl-1,3-propanediamine was 1:5, the catalyst was 6% NaOH and the product yield was about 64.72%. The grafting rate of the castor oil-based quaternary ammonium salt was about 99.6% when the amount of modifier was 0.69 g per 5 g of attapulgite, the ultrasound treatment time was 11 min and the pH was 5. The quaternary ammonium salt was only associated with the surface of attapulgite and did not change the rod-like crystal structure of the silicate. The modified attapulgite is much more fibrous and exhibits a good distribution of crystal bundles. The removal rates were found to be less favourable under strongly acidic and strongly alkaline conditions. Under suitable conditions, for 50 mL industrial wastewaters (phenol: 100–160 mg/L; acetone: 680–800 mg/L), the amount of modified attapulgite was 1 g, the temperature was 80 °C and the pH was 7, and the maximum removal rates of acetone and phenol after 80 min reached about 65.71% and 78.72%, respectively, which were higher than those of ATP.

“…After treatment, it becomes compatible with many polymer matrices (Liu et al , 2008; Yao et al , 2018; Chen et al , 2011). Therefore, Pal is used extensively as a polymer enforcer in polymer matrices (Xu et al , 2015). Chen et al treated Pal with an organic reagent to obtain an organic–inorganic hybrid (Chen et al , 2011).…”

Purpose The purpose of this study is to prepare a polydopamine (PDA)–palygorskite (Pal) hybrid-reinforced epoxy coating with high adhesion strength on wet concrete surface. Design/methodology/approach One synthetic step was adopted to prepare novel PDA–Pal hybrid epoxy coating. The process and product were analyzed and confirmed by FIRT, thermogravimetric analysis and scanning electron microscopy. The mass fraction of PDA–Pal hybrid affecting the adhesion strength of epoxy coating was analyzed and confirmed by pull-off test. Findings PDA–Pal hybrid mass fractions of 0, 1, 3 and 5 were added to the coatings. For a 5 Wt.% PDA–Pal hybrid content, the adhesive strengths on the saturated or underwater concrete surfaces increased to 4.0 and 2.5 MPa, respectively. In addition, the tensile mechanical property of the epoxy coating improved significantly after PDA–Pal addition. Practical implications This new epoxy coating hybrid by PDA–Pal could be applied as a concrete protective layer near water or in wet or damp environments. Originality/value Introduction of PDA–Pal hybrid to prepare epoxy coating with high adhesion strength on wet concrete surface has not been systematically studied previously.
