چکیده

در این تحقیق، تاثیر روش‌های مختلف خشک کردن بر نانو الیاف سلولزی و چندسازه‌های حاصل از آن بررسی شد. چهار روش برای خشک کردن سوسپانسیون نانو الیاف سلولز مورد استفاده قرار گرفت؛ روش هوای آزاد، خشک‌کن کوره‌ای، خشک‌کن پاششی و خشک‌کن انجمادی. ریخت‌شناسی و اندازه ذرات با استفاده از روش‌های تفرق نور لیزر (DLS)، آنالیز اندازه ذرات و میکروسکوپ الکترونی روبشی (SEM) مورد بررسی قرار گرفت. همچنین خواص مکانیکی فیلم‌های تقویت شده با این پودرها مطالعه گردید. از بین روش‌های مورد مطالعه فقط ذرات تهیه شده به روش پاششی در محدوده مقیاس نانو بوده و قابلیت ارتقاء چشم‌گیر خواص مکانیکی فیلم‌های برپایه پلی لاکتیک اسید (PLA) را دارا بودند.
