| dc.description.abstract | 本論文開發了一種綠色合成方法來生產銀奈米顆粒（AgNPs）、脫脂天然橡膠（SNR）和細菌纖維素（BC）的生物基半導體複合材料。將40至160 mM的硝酸銀 (AgNO3) 溶液添加到脫脂天然橡膠乳膠 (SNRL) 中，可促進銀離子在50至80°C的溫度下還原為AgNPs。隨後，將BC薄膜浸入製備的AgNPs-SNRL懸浮液中48小時，然後洗滌並乾燥。經過處理後的複合薄膜，其斷裂拉伸率大幅提升至13.8 %。由於AgNPs的摻入，該薄膜對金黃色葡萄球菌和大腸桿菌表現出強烈的抗菌活性。此外，AgNPs的存在顯著提高了薄膜的電導率至4.09 × 10-7 S/cm。初步濕度敏感度測試顯示，反應時間與恢復時間之比為3/20秒，濕度感應範圍較廣，從30% RH到90% RH。這些結果證明了AgNPs/SNR/BC複合薄膜在濕度感測器應用中極具潛力。 | zh_TW |
| dc.description.abstract | A green synthesis method was developed to produce biobased semiconducting composites of silver nanoparticles (AgNPs), skim natural rubber (SNR), and bacterial cellulose (BC). A solution of silver nitrate (AgNO3) ranging from 40 to 160 mM was added to skim natural rubber latex (SNRL) to facilitate the reduction of silver ions to AgNPs at temperatures between 50 and 80 °C. Subsequently, BC pellicle was immersed in the prepared AgNPs-SNRL suspension for 48 hours, followed by washing and drying. The resulting AgNPs/SNR/BC films were then analyzed for their chemical, mechanical, antibacterial, and electrical properties. The strain at break of the films was significantly enhanced to 13.8% under treatment with 80 mM AgNO3 at 80 °C. The films exhibited strong antibacterial activity against Staphylococcus aureus and Escherichia coli, due to the incorporation of AgNPs. Additionally, the presence of AgNPs significantly increased the electrical conductivity of the films to 4.09 × 10−7 S/cm. Preliminary humidity sensitivity tests revealed an excellent response time to recovery time ratio of 3/20 seconds, with a wide humidity-sensing range from 30% RH to 90% RH. These findings demonstrate the potential of AgNPs/SNR/BC composite films for use in humidity sensor applications. | en |
