Biodegradation study of enzymatically catalyzed interpenetrating polymer network: Evaluation of agrochemical release and impact on soil fertility

Biotechnology Reports, 2016
A novel interpenetrating polymer network (IPN) has been synthesized through enzymatic initiation using lipase as initiator, glutaraldehyde as cross-linker, acrylic acid as primary monomer and acrylamide as secondary monomer.

Shape memory behaviour of gelatin – alginate interpenetrating network hydrogel

, 2020
Gelatin – alginate interpenetrating network hydrogel was prepared. Glutaraldehyde was used to crosslink gelatin to form permanent netpoints for fixing the original shape of the hydrogel. Calcium ion was used to create coordination interaction with sodium

Biocompatible and Enzymatically Degradable Gels for 3D Cellular Encapsulation under Extreme Compressive Strain

Gels, 2021
Cell encapsulating scaffolds are necessary for the study of cellular mechanosensing of cultured cells. However, conventional scaffolds used for loading cells in bulk generally fail at low compressive strain, while hydrogels designed for high toughness ...

Wide-band underwater acoustic absorption based on locally resonant unit and interpenetrating network structure

, 2010
The interpenetrating network structure provides an interesting avenue to novel materials. Locally resonant phononic crystal (LRPC) exhibits excellent sound attenuation performance based on the periodical arrangement of sound wave scatters.

Carbodiimide‐Driven Toughening of Interpenetrated Polymer Networks

Angewandte Chemie, 2023
AbstractRecent work has demonstrated that temporary crosslinks in polymer networks generated by chemical “fuels” afford materials with large, transient changes in their mechanical properties. This can be accomplished in carboxylic‐acid‐functionalized polymer hydrogels using carbodiimides, which generate anhydride crosslinks with lifetimes on the order ...
