Abstract: A pressure impulse mitigating barrier including a crosslinked gel, the gel including water and gelatin which has been crosslinked using a functional silane compound, the compound including an electrophilic group (where the electrophilic group is not a silane) and a group of formula (B) where R is a C1-10 alkyl group, C6-10 aryl group, or C7-12 arylalkyl group; R? is a C1-10 alkyl group, C6-10 aryl group, or C7-12 arylalkyl group; n is 0-1, and where the functional silane has Mw of 800 g/mol or less.
Abstract: A multilayer armored panel comprising: (I) at least one layer that is non moldable when dry but moldable when wet; (II) at least one hydrogel based layer in contact with layer (I) which, when wet enables the molding of layer (I) but which is capable of drying out to leave a non moldable layer (I).
