Abstract

Research is conducted on the development of paper packaging materials with antibacterial properties using titanium dioxide nanoparticles. Titanium dioxide nanoparticles are synthesized by the hydrolysis of titanium tetrachloride in an alkaline medium, adjusting the pH value with an aqueous solution of ammonia at a temperature of 30 to 60°C. The influence of reaction conditions on the synthesis of titanium dioxide nanoparticles and the pH of the medium are studied and the optimal synthesis conditions are found. The processing parameters of paper packaging materials with aqueous solutions of titanium dioxide nanoparticles, which give them antimicrobial properties, are determined. Using electron-scanning microscopy and energy dispersive microanalysis, it is shown that untreated packaging paper contains 64.69% of C and 35.31% of O; after modification with a solution of titanium dioxide nanoparticles, titanium dioxide particles, which are distributed quite unevenly depending on the initial concentration of titanium dioxide nanoparticles, form on 16.46–21.14% of the surface of the treated paper. The packaging materials modified by the proposed composition show strong resistance to the action of microorganisms. The use of the developed antimicrobial food packaging reduces losses and preserves the quality and safety of food products during transportation, storage, and sales.

二氧化钛纳米微粒改性包装纸的研制

摘要

使用二氧化钛纳米颗粒对具有抗菌性能的纸包装材料的开发进行了研究。通过在碱性介质中四氯化钛的水解，在30至60℃的温度下用氨水溶液调节pH值来合成二氧化钛纳米颗粒。研究了反应条件对二氧化钛纳米粒子合成及介质pH值的影响，并确定了最佳合成条件。确定了具有二氧化钛纳米颗粒水溶液的纸包装材料的加工参数，这些参数赋予了它们抗菌性能。使用电子扫描显微镜和能量色散显微分析表明，未处理的包装纸含有64.69％的C和35.31％的O；在用二氧化钛纳米粒子的溶液改性后，根据二氧化钛纳米粒子的初始浓度，分布非常不均匀的二氧化钛粒子形成在被处理纸张表面的16.46–21.14％。通过提出的组合物改性的包装材料显示出对微生物作用的强抵抗力。使用已开发的抗菌食品包装可减少损失，并在运输，存储和销售过程中保持食品的质量和安全性。通过提出的组合物改性的包装材料显示出对微生物作用的强抵抗力。使用已开发的抗菌食品包装可减少损失，并在运输，存储和销售过程中保持食品的质量和安全性。通过提出的组合物改性的包装材料显示出对微生物作用的强抵抗力。使用已开发的抗菌食品包装可减少损失，并在运输，存储和销售过程中保持食品的质量和安全性。
