“…A peak at 1111 cm À1 is the characteristic peak of the MPEG side chain and indicates that the connections between OPEW and MPEG are done as reported by Charmi et al and Darounkola, previously. [27][28][29] Based on the FTIR spectrum results, the mechanism of the PEGylation reaction and the chemical structure of EOPEW are given in Scheme 1.…”

An ethoxylated polyethylene wax (E-OPEW) was synthesized by PEGylation reaction between methoxy polyethylene glycol and oxidized PE wax. Clay nanoparticles were modified with different ratios of E-OPEW and then compounded with PP by the melt mixing process. E-OPEW and PP showed excellent compatibility, but at high percentages of wax (15%), incompatibility occurred between the two phases. In addition, the presence of modified clays in the PP matrix decreased the crystallinity percentage, though it did not change the melting temperature significantly. The results showed that functionalized wax is able to penetrate between clay platelets and increase the distance between them and improve their dispersion in the polymer matrix. Furthermore, it was observed that the distance between clay platelets increased by increasing E-OPEW content. In addition, this result led to a significant improvement in the barrier properties of clay platelets and the thermal stability of the modified nanocomposite compared to other cases. Despite the improved dispersion of nanoparticles, the mechanical strength of nanocomposites decreased at a high percentage of E-OPEW.

LDH/P supramolecule with exfoliated and intercalated structure by exfoliation/adsorption and in situ polymerization method is prepared, respectively. Afterward, the LDH/polymer supramolecule with exfoliated (LDH/P‐E, exfoliation/adsorption) and intercalated (LDH/P‐I, in situ polymerization) and partial exfoliated and partial intercalated (LDH/P‐B, physical blending, reported in the previous work) is used in leather tanning and retanning process to evaluate the structure–activity relationship between LDH/P and leather application performance. LDH/P supramolecule with exfoliated structure shows the best intensification ability to most of the leather performances, and the sequence of intensification ability of LDH/P is LDH/P‐E > LDH/P‐B > LDH/P‐I. This is related to the size and penetration property of LDH/P. For the leather performance intensification, the positively charged LDH layers can promote the absorption of negatively charged leather chemicals, and thus the dyeing and softness of leather can be intensified. The nanolayered structure of LDH filled between leather gaps can play a toughening and block effect, and thus the physical and mechanical strength, thickening rate, and the inhibition of volatilization of small organic molecule property of leather can be intensified. Furthermore, the reduction of chemical oxygen demand value of dyeing waste water is also an evidence that the LDH/P is an environmental retanning auxiliary.
