Abstract

A comprehensive study of benzoxazines derived from magnolol and five different substituted aniline moieties through Mannich condensation was carried out. The structural confirmation was ascertained using different spectral analyses. Mg-a exhibited a lowest polymerization temperature of 220 °C than that of other monomers. Whereas, poly (Mg-ea) showed relatively the higher initial thermal stability until 411 °C with char yield of 56 % at 850 °C and enhanced values of limiting oxygen index (LOI) and statistic heat resistance index (HRI) than rest of polybenzoxazines. The Mg-pfa benzoxazine monomer exhibits significant antibacterial behavior with a maximum of 22 mm zone of inhibition and less cytotoxicity with IC50 value of 162 μg/ml as well as better corrosion resistant properties with 99 % corrosion inhibition efficiency. The hydrophobic studies indicated that poly (Mg-tfa) exhibited the highest water contact angle (CA) value of 143°. Poly (Mg-tfa) coated cotton fabric was resistant to chemical and UV treatments along with the 97 % of oil water separating efficiency. Polybenzoxazine composites were derived from poly (Mg-fa) matrix and cashew nut shell residue ash (CNA) and cashew nut shell carbon (CNC) fillers to ascertain influence on thermal, dielectric and hydrophobic properties. Poly (Mg-fa) composites reinforced with 15 wt% of CNA and 15 wt% of CNC exhibited dielectric constant values of 2.71 and 6.91 respectively at a frequency of 1 MHz. Findings from multifaceted studies indicate that the polybenzoxazines and composites reported in the present work can be utilized for anti-corrosion, anti-microbial, oil-water separation and electronic applications for improved performance and enhanced longevity.

受生物启发的含苯胺衍生物的可持续苯并恶嗪基复合材料：关于抗微生物、先进涂层、油水分离和电子利用的综合研究

研究人员对通过曼尼希缩合法从木兰醇和五种不同取代的苯胺分子中得到的苯并噁嗪类化合物进行了全面研究。通过不同的光谱分析确定了其结构。与其他单体相比，Mg-a 的聚合温度最低，仅为 220 摄氏度。与其他聚苯并噁嗪相比，聚（Mg-ea）的初始热稳定性相对较高，直到 411 摄氏度，在 850 摄氏度时的炭化率为 56%，极限氧指数（LOI）和统计耐热指数（HRI）也有所提高。Mg-pfa 苯并恶嗪单体具有显著的抗菌性能，最大抑菌区为 22 毫米，细胞毒性较低，IC50 值为 162 微克/毫升，同时具有更好的耐腐蚀性能，缓蚀效率高达 99%。疏水性研究表明，聚（Mg-tfa）的水接触角（CA）值最高，为 143o。聚(Mg-tfa)涂层棉织物耐化学和紫外线处理，油水分离效率高达 97%。聚苯并恶嗪复合材料由聚（Mg-fa）基体、腰果壳渣灰（CNA）和腰果壳碳（CNC）填料制成，以确定其对热性能、介电性能和疏水性能的影响。在频率为 1 MHz 时，15 wt% 的 CNA 和 15 wt% 的 CNC 增强聚（Mg-fa）复合材料的介电常数值分别为 2.71 和 6.91。多方面的研究结果表明，本研究中报告的聚苯并恶嗪及其复合材料可用于防腐蚀、抗微生物、油水分离和电子应用，以提高性能和延长使用寿命。
