摘 要 當(dāng)前，塑料帶來的環(huán)境污染日益突出，研究可降解塑料已經(jīng)受到社會的高度重視。其中光氧化-生物降解塑料是利用光降解機理和生物降解機理相結(jié)合的方法制得的一類塑料，是比較理想的降解塑料。它克服了單一光降解塑料和生物降解塑料的缺點，因而成為近年來國內(nèi)外研究的重點和熱門課題。 本論文用冰水浴法合成聚苯胺/二氧化鈦復(fù)合粒子，用紫外光分光光度計測試得，經(jīng)聚苯胺改性過的二氧化鈦的禁帶寬度明顯降低，增大了其對可見光的吸收，從而提高了對太陽光的利用率。將聚苯胺/二氧化鈦復(fù)合粒子填充在LDPE復(fù)合薄膜中，在紫外光光照下測其失重率。實驗結(jié)果表明：添加聚苯胺/二氧化鈦粒子的復(fù)合薄膜的失重率80.72%，而添加純二氧化鈦的復(fù)合薄膜和純的LDPE薄膜分別為67.19%和1.138%，這說明聚苯胺改性的二氧化鈦粒子有更好的光氧化降解效率，對薄膜的光氧化程度更大。 關(guān)鍵詞：聚苯胺/二氧化鈦 失重率 LDPE 復(fù)合薄膜 光氧化 |

Without the defects of single photodegradable plastic and biodegradable plastic, Photooxidation - biodegradable plastic has become a worldwide research focus and hot subject in recent years. 本論文 用 冰水浴法 合成 聚苯胺/二氧化鈦 復(fù)合粒子，用 紫外光分光光度計 測試得，經(jīng)聚苯胺 改性過的 二氧化鈦的 禁帶寬度 明顯降低，增大了 其 對可見光的 吸收，從而 提高了 對太陽光 的利用率。將 聚苯胺/二氧化鈦 復(fù)合粒子 填充在 LDPE復(fù)合薄膜中，在 紫外光光照下 測其 失重率。實驗 結(jié)果表明：添加 聚苯胺/二氧化鈦粒子 的 復(fù)合薄膜 的失重率80.72%，而添加 純二氧化鈦的 復(fù)合薄膜 和 純的LDPE薄膜 分別為67.19%和1.138%，這說明 聚苯胺 改性的 二氧化鈦粒子 有更好的 光氧化降解效率，對薄膜的 光氧化程度 更大。 In this paper, Polyaniline/titanium dioxide composite particles were prepared by ice-water bath method, and then it can be measured by ultraviolet spectrophotometer that the energy gap of titanium dioxide modified by polyaniline was significantly decreased, which enhanced the absorption of visible light, thus leading to increased use ratio of solar light. By filling polyaniline/titanium dioxide composite particles into LDPE laminated film, the weight loss ratio of film was measured under ultraviolet light. Results show that the weight loss ratio of laminated film added with polyaniline/titanium dioxide composite particles was 80.72%, while that of pure titanium dioxide laminated film and pure LDPE film was 67.19% and 1.138%, respectively, indicating that the polyaniline/titanium dioxide composite particles have higher photo-oxidative degradation efficiency and show greater photooxidation effect to laminated film. 關(guān)鍵詞：聚苯胺/二氧化鈦 失重率 LDPE 復(fù)合薄膜 光氧化 Keywords: Polyaniline/Titanium Dioxide; Weight Loss Ratio; LDPE; Laminated Film; Photooxidation |

Abstract: Plastic usage produced environmental pollution is becoming increasingly serious and research on degradable plastics has attracted much attention. Photooxidation-biodegradable plastic, which is produced based on a combined mechanism of photodegradation and biodegradation and considered an ideal degradable plastic, overcome the shortcoming of single photodegradable plastic and biodegradable plastic, and has become a world research focus. Polyaniline/titanium dioxide composite particles were synthesized by ice-water bath method, and ultraviolet spectrophotometer measurement show that the forbidden bands width of polyaniline-modified titanium dioxide was significantly decreased, which enhanced its absorption of visible light, thus leading to an increased utilization of solar light. The weight loss ratio of LDPE laminated films were measured and results show that the weight loss ratio of the laminated film added with polyaniline/titanium dioxide composite particles was 80.72%, while that of pure titanium dioxide laminated film and pure LDPE film was 67.19% and 1.138%, respectively, indicating that the polyaniline/titanium dioxide composite particles have higher photo-oxidative degradation efficiency and greater photooxidation effect to laminated film.
