中文摘要 | 本研究之目的是探討高分子複合材料應用於太陽能集熱板,其熱性質及 耐候性質。本文採用聚丙烯(pp)為高分子基材,添加入不同含量之填充物(碳酸 鈣,碳黑)後,探討此複合材料之熱導係數,機械性質及老化性質,同時以掃描 式電子顯微鏡SEM來觀察此複合材料之形態。實驗結果顯示,複合材料之熱導係 數隨填充物含量增大而增大,但隨溫度的增高呈線性地減小。填充少量碳黑對其 抗拉強度有補強作制,但含量高時強度卻會降低。而填充碳酸鈣者,抗拉強度則 會降低,由SEM照片觀察,可以看到填充物粒子具有很好的分散性。 |
英文摘要 | The objective of this work is to study the thermal and weathering properties ofpolymer composites for their application to the solar energy collector. Polypropylene(PP) was selected as the base material, mixed with various contents of fillers (calcium carbonate (CaCO3) or carbon black). The thermal conductivity, mechanicalproperties and aging behavior of.PP/CaCO3, and PP/carbon black composites weremeasured. The morphologies of the composites were examined by a scanning electron microscope (SEM). Experimental results showed that the thermal conductivitiesof polymer composites increased with increasing content of fillers, but decreasedlinearly with a rise in temperature. The tensile strength increased first and thendecreased with increasing content of carbon black, but it decreased monotonouslywith the addition of CaCo3. The particles of CaCO3 and carbon black dispersedrather uniformly in PP matrix from the SEM observation. |
