METHOD FOR PREPARING A HYDROGEL MATRIX BY PHOTOPOLYMERIZATION

摘要

The invention relates to a method for preparing a hydrogel matrix comprising at least two contiguous zones of distinct rigidities, comprising a step of photopolymerization of a solution comprising one or more polymerizable compounds and a photopolymerization initiator, by application of a light on the entire solution and according to a different intensity at the level of at least two zones of the solution, as a result of which a hydrogel matrix is produced which comprises at least two contiguous zones of distinct rigidities, characterized in that the step of photopolymerization is carried out in the presence of a polymerization catalyst.
