Complex-Forming Polyoxyethylene: Poly(acrylic acid) Interpenetrating Polymer Networks III. Swelling and Mechanochemical Behavior

Dynamic swelling behavior of interpenetrating polymer networks in response to temperature and pH.

Temperature responsive hydrogels based on ionic polymers exhibit swelling transitions in aqueous solutions as a function of shifting pH and ionic strength, in addition to temperature. Applying these hydrogels to useful applications, particularly for biomedical purposes such as drug delivery and regenerative medicine, is critically dependent on understanding the hydrogel solution responses as a ...

Interpenetrating Polymer Networks (IPN

Interpenetrating polymer network (IPN) refers to a type of elastomer in which two chemically distinct networks coexist, ideally having a structure that is homogeneous down to the segmental level [1]. The two components are present as co-continuous, interlocking networks (catenanes). This co-continuity can be achieved by kinetic retention of an initially miscible mixture of the monomers used to ...

Biomimetic interfacial interpenetrating polymer networks control neural stem cell behavior.

Highly-regulated signals surrounding stem cells, such as growth factors at specific concentrations and matrix mechanical stiffness, have been implicated in modulating stem cell proliferation and maturation. However, tight control of proliferation and lineage commitment signals is rarely achieved during growth outside the body, since the spectrum of biochemical and mechanical signals that govern...
