Stage 2: The preparation optimization of new polysulfone-POSS membranes with ionic liquids (Months 2-15). Approach:
A.2.1. The surface characterization and CO2 adsorption and capture (Months 10-21): The deliverables for this activity are the following. We will fabricate ≥ 10 samples of membranes, such as the material from Stage 1. The total area of the samples will feature dimensions such as an area of ≥ 4 cm ²and a thickness of ≤ 3 mm, with a datasheet for the products.

A.2.2. The preparation optimization of new polysulfone-POSS membranes with ionic liquids (Months 13-24): The PS-POSS-IL membranes will be characterized in terms of FTIR spectroscopy, mechanical properties, air and CO2 permeability.

A.2.3. The properties optimization of the polysulfone-POSS membranes with different ionic liquids contents (Months 13-24): The parameters of preparation process and characterization of the membranes and the best neural network model choose for the principal objective of the project.

A.2.5. Dissemination of results and intellectual property rights The project will generate knowledge, technology and product with potential applicability. Fundamental research results will be published. It is expected to be published four papers in ISI indexed journals, relevant to the stages to be accomplished, with two papers in open access journal. The results will be disseminating through participation and presentation at seven conferences. Moreover, the results with potential further applicability will be included in one patent application.

Expected results:
- 2 ISI papers, 3 conference presentations; 5 types of polysulfone-POSS containing ionic liquids membranes

A.2.6. Scientific Management. The project director is responsible for scientific management by monitoring compliance of the project work plan and working protocols established, periodic evaluation of the results obtained, adjust working strategies if necessary, dissemination of research results by publishing at least the number of scientific articles, performance of the steps for obtaining intellectual property.

A.2.7. Legal and economic-financial management. Financial management will consist of: following the compliance of the project financial plan for the activities planned and its revision if necessary (in case of deviations from the initial plan); accounting of all financial activities related to the project (purchases, salaries, travel); developing the project financial report, financial audit of the project. The jurist will permanently monitor the compliance of legislation in all activities related to project implementation, will draw up employment contracts or amendments to contracts of employment for persons employed on the project.

All activities proposed to be carried out in Stage I of the AI-Syn-PPOSS project were fully carried out. The results obtained through the implementation of the AI-Syn-PPOSS project during the second stage of development were disseminated at international scientific events, in the form of oral and poster communications, as well as in the form of four published articles, one article accepted for publication.
