style="text-indent:25px">為了保持果蔬的新鮮程度,延長其貯藏時間,常用冷藏、氣調(diào)、輻射等技術(shù)進行處理,但這些技術(shù)存在操作復雜,成本高等不足,而價格較低的市售保鮮膜則存在功能性差、污染環(huán)境等問題。本文采用靜電紡絲技術(shù),以聚乳酸(PLA)為基材、高活性納米TiO2為添加材料,制備出TiO2/PLA復合納米纖維膜并探討了該材料在果蔬保鮮包裝領(lǐng)域中的潛在應(yīng)用性。為制備出高活性的納米TiO2,采用水熱沉淀法以***鈦和尿素為原料進行合成。以甲基橙降解實驗測試納米TiO2的光催化活性,并對其進行X射線衍射儀(XRD)表征和超聲分散性能測試,結(jié)果表明:納米TiO2比較好的制備工藝參數(shù)為***鈦:尿素=1:4、反應(yīng)溫度為180℃、反應(yīng)時間為4h,所制備的TiO2是一種平均晶粒尺寸為13.76nm的銳鈦礦相晶體,其比較好的超聲分散功率為960W,時間為60min。為實現(xiàn)TiO2/PLA復合納米纖維膜的制備,先采用理論分析與實驗探究相結(jié)合的方式,確定了紡絲溶劑和紡絲工藝參數(shù),制備出純PLA納米纖維膜,再采用TiO2與PLA共混溶液靜電紡絲的方式制備出TiO2/PLA復合納米纖維膜,</p><p style="text-indent:25px">按照二次原料70%、母料30%的配比，每噸可降解塑料袋的生產(chǎn)成本約為7900元，若生產(chǎn)5g塑料袋，每噸原料可產(chǎn)20萬個，平攤下來提高的成本微乎其微。目前所掌握的生物降解母料生產(chǎn)技術(shù)可按需要控制塑料制品的降解期，能夠生產(chǎn)可降解購物袋、垃圾袋、可降解地膜、生物降解制品及編織制品，使用時只需將母料加入正常原料之中，對設(shè)備沒有升級要求。但由于環(huán)保性的塑料制品未形成規(guī)模，所以短期內(nèi)塑料袋，想說再見不容易。有一組數(shù)字可以窺見一斑而知全貌：84%的人認為“限塑令”對生活幾乎沒有影響，11%的人表示影響不大，只有5%的人表示影響非常大。第三。限塑令的頒布實乃治表不治本之無奈之舉。我們再來看看一組數(shù)據(jù)：42%的人表示，塑料袋收費后，限制了人們對塑料袋的使用;25%的人表示，增加了消費者的成本;33%的人表示，盡管該舉措一定程度上限制了人們對塑料袋的使用，但對環(huán)保的初衷來說，是治標不治本，畢竟，幾角錢的費用在整個購物成本中，只能算作是“小錢”。那么，“限塑令”意義何在?從***辦公廳發(fā)布的《通知》中，可以找到答案。《通知》中提到，“塑料購物袋在為消費者提供便利的同時，由于過量使用及回收處理不到位等原因。35為改善原淀粉膜的脆性和成膜性,以甘油為增塑劑,采用高速攪拌及流延法制備了高淀粉含量的玉米淀粉膜!</p><div
