“…Benefits from the low‐cost, eco‐friendly, and presence of abundant pyrogallol and catechol groups makes it highly possessive of various applications, such as absorption, coating, food additives, and biomedical materials . In some recent studies, Tang et al reported that TA was introduced as a modifier in boehmite‐filled styrene‐butadiene rubber composites, which have enhanced the mechanical properties and gas barrier property of the rubber. Liu et al investigated TA as a vulcanizing agent to crosslink epoxidized soybean oil (ESO).…”

In this work, hybrid composites are consisting of single wall carbon nanotubes (CNT) and tannic acid (TA) embedded in nitrile butadiene rubber (NBR) matrix using kneading followed by the hot‐pressing method. The CNT and TA were mixed to NBR at different ratio and the obtained composites were subjected to morphological, rheological and thermal analysis as well as mechanical properties. The tensile test results manifested that both CNT and TA can be used as the reinforcing fillers, while the NBR composites filled with CNT exhibited a stronger mechanical behavior, indicating CNT was shown to be the more effective in tensile strength. Furthermore, the organic‐inorganic hybrid fillers presented enhancement of mechanical properties as compared to the neat NBR.

“…According to the studies, DOPO alone could reduce the T g of epoxy resin by decreasing the crosslinking density of the resin network. However, boehmite combined with DOPO and Si enhanced T g because of the consumption of P–H in rigid DOPO groups and the restriction of the molecular chain motion of epoxy by boehmite and the Si–O–Si network . A T g depression was observed for epoxy containing low AlOOH−DOPO−GPTS contents because of the plasticizing effect .…”

“…It can be used as a nanofiller to improve the mechanical properties of the polymer, and its tailorable surfaces could make it easier to disperse evenly in resin . Several modification methods, including improvements by silane or natural acids, have been proposed to improve the dispersion of AlOOH in polymers . Nevertheless, to obtain an appropriate flame retardancy, high loadings of AlOOH in epoxy resin are required, and this will sacrifice other properties .…”

To improve the liquid oxygen compatibility and cryogenic mechanical properties of epoxy resin, we synthesized and characterized a hybrid compound (functionalized boehmite) containing boehmite, phosphorus, and silicon element. The thermal properties and liquid oxygen compatibility of the composites were investigated in detail. The results show that the addition of functionalized boehmite increased the char residue obviously but had little effect on the thermal decomposition temperature and glass-transition temperature of the composites. The liquid oxygen compatibility of the composites was significantly improved. Composites with 4 wt % boehmite, 0.99 wt % Si, and 1.1 wt % P passed the impact test. Surface element analyses before and after the drop tests suggested that the functionalized boehmite in epoxy might have prevented the impact reaction in liquid oxygen through two steps. First, the compound decomposed into phosphoric oxyacid and Al 2 O 3 under the impact energy and captured the H• and •OH radicals produced from the decomposition of the resin. Then, the decomposition covered the surface, forming a protective layer to isolate the oxygen. The mechanism of the liquid oxygen compatibility of the epoxy composites was subsequently analyzed. In addition, the cryogenic tensile properties of the epoxy composites containing functionalized boehmite showed that the composites had potential applications under cryogenic liquid oxygen environments.

Toward Mechanically Robust Crosslinked Elastomers through Phase Transfer Agent Tuning the Solubility of Zn2+ in the Organic Phase

et al. 2022

Zinc oxide (ZnO), which is toxic to aquatic organisms, is widely used as an activator in the rubber industry. The reduction of ZnO content is one of the efficient ways to tackle ecological environment impacts induced by ZnO. However, the incompatibility between Zn2+ and organic matrix inhibits the solubility and activity of Zn2+ in the organic matrix, causing the heavy use of ZnO. This work develops a phase transfer agent with Zn2+-philic structure and oleophilic structure to increase the solubility of Zn2+ in the organic matrix. The phase transfer agent and Zn2+ form coordination interactions, while the hydrophobic chains of phase transfer agent and organic matrix form hydrophobic interactions. The above two interactions improve the solubility and activity of Zn2+ in the organic matrix, contributing to the formation of crosslinking network. Through the phase transfer agent strategy, we obtain the mechanically robust elastomers, and the samples with low ZnO content still maintain the superior properties. This work provides an efficient way to reduce ZnO content without sacrificing the performance of elastomers.
