POLYMER GELATIN OBTAINED FROM MARINE NATURAL SOURCES ADAPTED TO COLD AND ITS USE

摘要

The present invention refers to a composition comprising a solution which in turn comprises an amino acidic chain gelatin polymer derived from natural sources of cold-adapted marine species, at a concentration from 1% to 20% (w/v), which optionally further comprises a polymerizing initiator such as a photoinitiator, and is chemically functionalized to become reactive to polymerization or crosslinking in presence of free radicals. This composition is especially useful for 3D printing, extrusion systems (additive fabrication), spray systems, casting, micro- and nano fibers fabrication systems (electrospinning, solution blow spinning) or microfluidics.
