Flory-Huggins 理论用于模拟线性低密度聚乙烯-香茅醛二元混合物的相行为。模型参数是通过使用浊点测定的数据点拟合双峰相包络而获得的。这使得可以预测熔点下降曲线以及旋节线区域的位置。通过在远低于旋节线相界的温度下淬火均匀液体混合物获得微孔聚乙烯基质。这种策略使得在聚乙烯 (LLDPE) 基质中捕获并有效固化大量香茅醛成为可能。这对于开发持久的驱虫手镯和脚链具有潜在的意义。 (C) 2015 Elsevier B.V. 保留所有权利。
The Flory-Huggins theory was used to model the phase behaviour of linear low density polyethylene-citronellal binary mixtures. The model parameters were obtained from fitting the bimodal phase envelope using data points from cloud point determinations. This allowed the prediction of the melting point depression curve as well as the location of the spinodal region. A microporous polyethylene matrix was obtained by quenching homogeneous liquid mixtures at temperatures well below the spinodal phase boundary. This strategy makes it possible to trap, and effectively solidify, large amounts of citronellal in a polyethylene (LLDPE) matrix. This has potential implications for the development of long-lasting insect repellent bracelets and anklets. (C) 2015 Elsevier B.V. All rights reserved.
