Resumo

Tal como qualquer outro material, as telas são suscetíveis à degradação, levando à perda da capacidade dos têxteis de suportar as camadas de tinta. Historicamente, o revestimento tem sido o método predominante para resolver o problema. Os riscos associados a esta abordagem têm sido amplamente documentados, encaminhando para soluções alternativas. A utilização de nanocristais de celulose (CNC) para o tratamento de consolidação representa uma alternativa biológica aos produtos de conservação convencionais, com vantagens na compatibilidade e sustentabilidade. Com base em estudos anteriores, a investigação de doutoramento em curso visa aprofundar a compreensão de questões-chave relacionadas com os CNC, que não foram suficientemente exploradas em estudos anteriores. Estas incluem aspetos como a penetração dos CNC no substrato, a sua adesão à tela e métodos para reduzir a quantidade de água necessária para a sua aplicação. O objetivo principal deste estudo é evidenciar as potencialidades e limitações de um material ecológico promissor.
