چکیده | ||
در تحقیق حاضر، بررسی میشود که چگونه سنتز نانوذرات و نانوساختارهای آلومینیوم هیدروکسید و نقره، به عنوان پوششهایی بر روی سطح چوب، میتواند خواص ضد قارچی و ماندگاری بیشتر آن را افزایش دهد. برای سنتز، از روش ماکروویو استفاده شده است و سپس خواص پوششهای حاصل، از جمله خواص ضدباکتریایی و ضدآتشسوزی، با استفاده از تحلیلهای SEM، XRD، TGA، و آزمونهای آتشسوزی UL-94 و ضریب حداقل اکسیژن مورد بررسی قرار گرفته است. نتایج پژوهش نشان میدهد که پوششهای دولایه با نقره و آلومینیوم هیدروکسید، به ترتیب، خواص ضد قارچی و ماندگاری بیشتر بهتری را نسبت به پوششهایتک لایه دارند. همچنین، در آخرین نمونه که از هر دو نمک آلومینیوم نیترات و نقره نیترات استفاده شده است، همگرایی بین خواص ضد قارچی و ماندگاری بیشتر بهخوبی مشاهده شده است. | ||

چکیده [English] | ||
This paper investigates how the synthesis of aluminum hydroxide, silver nanoparticles, and nanostructures, as coatings on wood surfaces, can enhance their antifungal and fire-retardant properties. The microwave method is employed for synthesis to investigate properties of the resulting coatings, including antibacterial and fire-retardant properties. They have been examined using SEM, XRD, TGA analyses, fire tests such as UL-94 , and Limiting Oxygen Index (LOI). The results show that bilayer coatings with silver and aluminum hydroxide, respectively, have better antifungal and fire-retardant properties compared to single-layer coatings ones. Furthermore, in the another sample, where both aluminum nitrate and silver nitrate salts are used simultaneously, a good correlation between antifungal and fire-retardant properties has been observed. Overall, these findings contribute to a deeper understanding of the functional properties and potential applications of silver and aluminum hydroxide-coated wood surfaces in various fields such as antimicrobial coatings and environmental remediation. | ||
