Abstract

Polymethylmethacrylate, PMMA, with sponge or finger pores are interesting depending on the application. Our goal was to investigate parameters (Φ and Φ’) to foresee the morphology of PMMA prepared by phase inversion based on chemical composition (amount and type of solvent, non-solvent and surfactant). A literature survey was conducted with different chemical composition and analyzed by statistical tools. Sponge-like structures were obtained in systems whose Φ value is less than 0.22 or the Φ’ value is more than 0.55. Both indexes can differentiate to some extent systems that generate finger-like structures from those that generate sponge-like ones.

调节湿相反转制备的聚甲基丙烯酸甲酯结构的溶剂和凝固介质的选择标准

聚甲基丙烯酸甲酯（PMMA）具有海绵孔或指状孔，这取决于其应用领域。我们的目标是根据化学成分（溶剂、非溶剂和表面活性剂的数量和类型）研究参数（Φ 和 Φ'），以预测通过相反转制备的 PMMA 的形态。对不同化学成分进行了文献调查，并利用统计工具进行了分析。在 Φ 值小于 0.22 或 Φ' 值大于 0.55 的体系中获得了海绵状结构。这两个指标都能在一定程度上区分产生指状结构的系统和产生海绵状结构的系统。

期刊介绍： Orbital: The Electronic Journal of Chemistry is a quarterly scientific journal published by the Institute of Chemistry of the Universidade Federal de Mato Grosso do Sul, Brazil. Original contributions (in English) are welcome, which focus on all areas of Chemistry and their interfaces with Pharmacy, Biology, and Physics. Neither authors nor readers have to pay fees. The journal has an editorial team of scientists drawn from regions throughout Brazil and world, ensuring high standards for the texts published. The following categories are available for contributions: 1. Full papers 2. Reviews 3. Papers on Education 4. History of Chemistry 5. Short communications 6. Technical notes 7. Letters to the Editor The Orbital journal also publishes a number of special issues in addition to the regular ones. The central objectives of Orbital are threefold: (i) to provide the general scientific community (at regional, Brazilian, and worldwide levels) with a formal channel for the communication and dissemination of the Chemistry-related literature output by publishing original papers based on solid research and by reporting contributions which further knowledge in the field; (ii) to provide the community with open, free access to the full content of the journal, and (iii) to constitute a valuable channel for the dissemination of Chemistry-related investigations.
