Resumo: | This work presents a ?cradle-to-gate? Life Cycle Assessment (LCA) of 3Dprinting polymerisable ionic liquids (PILs) using stereolithography apparathus. Firstly, in order to provide an up-to-date overview on the currently state-of-the-art involving the life cycle assessment (LCA) studies on ionic liquids (ILs) a review on the subject was employed. This review recommends a list of issues that need further precision for application of LCA to evaluate ILs processes, such as: i) access to comprehensive and adequate life cycle inventory and ii) development and inclusion of characterization factors for IL impacts. Also, some good practices in LCA of IL were identified and are recommended. Later, this work focused on the employment of the 3-butyl-1-vinylimidazolium [BVim] cation, with the non-coordinating and hydrophobic bis(trifluoromethane)sulfonimide [NTf2]- anion as the counter anion. The results indicate that the printing process does not significantly exacerbate the environmental impacts. The polymerisable monomer IL has similar impact compared to the analogous non-polymerisable 3-butyl-1-methylimidazolium [NTf2]- IL, thus potentially allowing for the more efficient use of the IL properties by immobilization in solid phases. Furthermore, it is demonstrated that switching the anion from [NTf2]- to dicyanamide [N(CN2)]- significantly decreases the impacts in all categories evaluated for PIL production. This work represents the first phase toward quantitative LCA data generation for the process of 3D-printing IL, which will be great support for decision making during design of PIL 3D-printing processes at a laboratory scale. |

Primeiramente, a fim de fornecer uma vis?o geral atualizada sobre o estado da arte envolvendo os estudos da ACV em l?quidos i?nicos (LIs), uma revis?o sobre o tema foi conduzida. Esta revis?o recomenda uma lista de quest?es que requerem de maior aten??o para a aplica??o da ACV para avaliar os processos de LIs, tais como: i) acesso a um invent?rio completo e adequado do ciclo de vida e ii) desenvolvimento e inclus?o de fatores de caracteriza??o de impactos de LIs. Al?m disso, algumas boas pr?ticas em ACV de LI foram identificadas e s?o recomendadas. Posteriormente, este trabalho teve como foco o emprego do c?tion 3-butil-1-vinilimidaz?lio ([BVim]+), com o ?nion n?o-coordenado e hidrof?bico bis(trifluorometanosulfonil)imidato ([NTf2]-) como contra-?on. Os resultados indicam que o processo de impress?o n?o exacerba significativamente os impactos ambientais. O mon?mero polimeriz?vel de LI tem impacto compar?vel ao an?logo, n?o-polimeriz?vel, 3-butil-1-metilimidaz?lio [NTf2]-, portanto, permitindo potencialmente o uso mais eficiente das propriedades dos LI por imobiliza??o em fases s?lidas. Tamb?m, ? demonstrado que a troca do ?nion [NTf2]- pelo ?nion dicianamida [N(CN2)]-, para produ??o de PILs, diminui significativamente os impactos em todas as categorias avaliadas. Este trabalho representa a primeira fase em dire??o ? gera??o quantitativa de dados de ACV, para o processo de impress?o 3D de PILs, que ser? um grande suporte para a tomada de decis?es durante o projeto de desenvolvimento de processos de impress?o 3D de PILs em escala de laborat?rio.Submitted by PPG Engenharia e Tecnologia de Materiais (engenharia.pg.materiais@pucrs.br) on 2019-01-11T18:10:26Z No. of bitstreams: 1 vers?o final vinicius.pdf: 7710156 bytes, checksum: ff30c6a366731378b7bcf5c6aeb3e372 (MD5)Approved for entry into archive by Caroline Xavier (caroline.xavier@pucrs.br) on 2019-01-18T11:19:46Z (GMT) No. of bitstreams: 1 vers?o final vinicius.pdf: 7710156 bytes, checksum: ff30c6a366731378b7bcf5c6aeb3e372 (MD5)Made available in DSpace on 2019-01-18T11:30:19Z (GMT).
