Polimero biobateragarrien garapena biomedikuntzan erabiltzeko

Abstract

Plastiko biobateragarrien garapenak erronka zientifikoa izaten jarraitzen du biomedikuntzan material hauek erabili ahal izateko. Polimeroen artean, poliuretanoak (PUak) oso erabiliak dira eta gainera azken urteetan forma-memoria duten PUak asko garatu dira. Hauek estimulu baten aurrean forma aldatzeko gaitasuna dute eta horrela, beste polimero batzuekin lor ezin daitezkeen aplikazioetan erabilgarriak izan daitezke. Izan ere, gaur egun ingurumena kaltetzen ez duten materialen sintesian oraindik garapen asko falta da. Lan honetan, biobateragarriak diren forma-memoria PUetan sakonduko da.

The development of biocompatible plastics remains a scientific challenge for the use of these materials in biomedicine. Among them, polyurethanes (PUs) are widely used and, in recent years, PUs with shape memory have developed a lot. These have the ability to change the shape before a stimulus and can be useful in applications that cannot be achieved with other polymers. In fact, much development is still lacking in the synthesis of materials that currently do not harm the environment. This work will delve into the biocompatible shape memory PUs.
