| چکیده | ||
| Surface engineering of polymeric materials is essential for improving their properties in various applications. In this study, we investigate the formation of similar morphological structures on the surface of polymethyl-methacrylate (PMMA) following irradiation of nanosecond ultraviolet (UV) and infrared (IR) lasers. Above the ablation threshold, and under certain irradiation conditions, both UV and IR irradiations lead to the formation of micropores due to thermal stress and impurities. Again, irradiation of the samples first at a fluence above and then below the ablation threshold, with UV wavelength, leads to the formation of bumpy structures, compared to the nanospheres formed following IR irradiation. Our findings provide insights into laser-induced surface modifications in polymers and contribute to the development of controlled surface engineering techniques. | ||

| چکیده [English] | ||
| مهندسی سطح مواد پلیمری برای بهبود خواص آنها در کاربردهای مختلف ضروری است. در این مطالعه، ما تشکیل ساختارهای مورفولوژیکی مشابه را بر روی سطح پلی متیل متاکریلات (PMMA) به دنبال تابش لیزرهای نانوثانیه فرابنفش (UV) و مادون قرمز (IR) بررسی می‌کنیم. بالاتر از آستانه فرسایش، و تحت شرایط تابش خاص، هر دو تابش UV و IR منجر به تشکیل منافذ ریز به دلیل استرس حرارتی و ناخالصی‌ها می‌شوند. از سویی دیگر، تابش نمونه‌ها ابتدا در یک شاریدگی بالا و سپس زیر آستانه فرسایش، با طول موج UV، منجر به تشکیل ساختارهای ناهموار می‌شود، که با نانو کره‌هایی که پس از تابش IR تشکیل می‌شوند، مقایسه می گردند. یافته‌های ما بینش‌هایی را در مورد تغییرات سطحی ناشی از لیزر در پلیمرها ارائه می‌دهد و به توسعه تکنیک‌های مهندسی سطح کنترل‌شده کمک می‌کند. | ||
