| هدف این پژوهش بررسی خصوصیات فیزیکی و مکانیکی نانوچندسازه چوب-پلاستیک حاصل از نانولوله کربنی خام و عامل‌دار می باشد. بدین منظور، آردچوب به مقدار ثابت 50 درصد، نانولوله‌های کربنی خام در 3 سطح 0، 1 و 2 درصد و جفت‌کننده مالئیکی در دو سطح 0 و 3 درصد در زمینه پلی‌اتیلن‌سنگین مورد استفاده قرار گرفت. همچنین از نانولوله کربنی عامل‌دار جهت تقویت کارایی نانوچندسازه در دو سطح 1 و 2 درصد به صورت جداگانه استفاده شد. مواد در مخلوط‌کن داخلی(Haake) با هم آمیخته شده و سپس نمونه‌ها توسط دستگاه پرس گرم ساخته شدند. نتایج نشان داد که با افزایش مقدار نانولوله کربنی از 0 به 2 درصد وزنی، استحکام و مدول الاستیسته کششی نمونه‌ها به ترتیب 8/58 و 6/12 درصد افزایش و جذب آب و واکشیدگی ضخامتی به میزان 5/54 و 4/19 کاهش یافت. چندسازه‌های حاوی 2 درصد وزنی نانولوله کربنی در مقایسه با چندسازه شاهد، مقاومت به ضربه بالاتری از خود نشان دادند. عامل جفت کننده مالئیکی اثر مثبتی بر کارایی نانوچندسازه‌ها داشت. خواص فیزیکی و مکانیکی نمونه‌ها با افزودن جفت کننده و نانولوله کربنی عامل‌دار بهبود محسوسی یافت. نتایج توسط میکروسکوپ الکترونی روبشی نیز مورد تأیید قرار گرفت. | ||

| چکیده [English] | ||
| The purpose of this research is to investigate the physical and mechanical properties of the wood-plastic nanocomposite obtained from Raw and Functionalized carbon nanotubes (CNTs). For this purpose, wood flour at a fixed amount of 50%, Raw CNTs at three levels of 0, 1 and 2% and coupling agent at two levels of 0 and 3% were used in HDPE matrix. Also, Functionalized CNTS were used to strengthen the efficiency of nanocomposites at 1 and 2% levels separately. The materials were mixed together in an internal mixer (Haake) and then the samples were made by a hot press machine. The results showed that by increasing the amount of CNTs from 0 to 2% wt, the tensile strength and modulus of the samples increased by 58.8% and 12.6% respectively, and water absorption and thickness shrinkage decreased by 54.5% and 19.4% respectively. Composites containing 2% wt of CNTs showed higher impact resistance compared to control samples. The coupling agent had a positive effect on the performance of nanocomposites. The physical and mechanical properties of the samples were significantly improved by adding the coupling agent and Functionalized CNTs. The results were also confirmed by scanning electron microscopy. | ||
