“…According to Figure 10, the failure temperature of BBM was 69.07 • C and the failure temperature of MBM with LDHs was 71.07 • C. LDHs could improve the high-temperature rheological properties of BM, consistent with the physical property test results. The effect of LDHs on the hightemperature rheological properties of BM was less than that on the high-temperature rheological properties of bitumen [18]. This might be due to the addition of fillers that weakened the effect.…”

“…In recent years, research on LDHs as bitumen antiaging modifiers has also received much attention. He et al found that LDHs improved the resistance of bitumen to deformation at high temperatures and protected its physicochemical properties, rheological properties, and chemical composition under UV aging [18]. Cao et al investigated the effect of different particle sizes of LDHs on the UV aging resistance of asphalt using viscosity tests, dynamic shear rheometer (DSR) tests and Fourier-transform infrared spectroscopy (FTIR) tests [19].…”

Layered double hydroxides (LDHs) can shield polymeric materials from UV light, which allows reducing material aging and erosion damage of bituminous pavement under physical and chemical action. In this study, the physicochemical properties, aging resistance, and erosion resistance to the aqueous solution of LDHs modified bitumen mastic (BM) were characterized by Fourier-transform infrared spectroscopy, basic physical tests, viscosity tests, a dynamic shear rheometer, and a bending beam rheometer. The results show that few chemical reactions occurred between LDHs and BM, indicating that a physical mechanism underlay the modification of BM by LDHs. Moreover, LDHs could increase the flow activation energy of BM by 0.12%, increase the high failure temperature from 69.07 °C to 71.07 °C, and decrease the low failure temperature from −10.50 °C to −12.39 °C. Therefore, LDHs could slightly reduce the temperature sensitivity of BM, while slightly enhancing the high and low-temperature rheological properties of BM. Compared with short-term aging and long-term aging, LDHs could significantly improve the UV aging resistance of BM. The above results are consistent with previous studies of LDHs-modified bitumen. Furthermore, water and pH 3 acidic solutions had the greatest degree of erosion to BM, and LDHs could improve the resistance to aqueous solutions. Overall, this study can help to investigate the effects of various environmental factors on the performance of LDHs modified bitumen pavements during long-term use.

“… 18,21 To settle the issue, some organic anion compounds were replaced into the interlamination of LDH, like lignosulfonate, salicylic acid, p -methycinnamic acid, etc. 22–24 Although intercalated LDH shows better effectiveness on the anti-aging performance of bitumen, unfortunately, the essential question (the hydroxide radical) of LDH has not been solved. Silane coupling agent is often used to heighten the compatibility between inorganic materials and organic materials.…”

“…Lignosulfonate is utilized as dispersants, water reducers and other low value-added products. In recent years, lignosulfonate was used as an anti-ultraviolet additive, a strengthening agent for films and gel materials in high-quality applications [ 22 , 23 , 24 , 25 ]. These unique properties of lignosulfonate are utilized to overcome the shortcomings of poor mechanical strength of konjac glucomannan, which is beneficial to the development of low-cost, high-performance composite materials.…”

In order to enforce the mechanical strength and antibacterial ability of biofilm and explore the underlying mechanism, sodium lignosulfonate (SL) and ε-polylysine (ε-PL) were introduced to fabricate the composite film of konjac glucomannan (KGM)/SL/ε-PL in the present study. According to our previous method, 1% (w/v) of KGM was the optimal concentration for the film preparation method, on the basis of which the amount of SL and ε-PL were screened by mechanical properties enforcement of film. The structure, mechanical performance and thermal stability of the film were characterized by SEM, FTIR, TGA and tensile strength tests. The optimized composite film was comprised of KGM 1% (w/v), SL 0.2% (w/v), and ε-PL 0.375% (w/v). The tensile strength (105.97 ± 4.58 MPa, p < 0.05) and elongation at break (95.71 ± 5.02%, p < 0.05) of the KGM/SL/ε-PL composite film was greatly improved compared with that of KGM. Meanwhile, the thermal stability and antibacterial property of film were also enhanced by the presence of SL and ε-PL. In co-culturation mode, the KGM/SL/ε-PL composite film showed good inhibitory effect on Escherichia coli (22.50 ± 0.31 mm, p < 0.05) and Staphylococcus aureus (19.69 ± 0.36 mm, p < 0.05) by determining the inhibition zone diameter. It was revealed that KGM/SL/ε-PL composite film shows enhanced mechanical strength and reliable antibacterial activities and it could be a potential candidate in the field of food packaging.
