Interpenetrating polymer network
WebA hybrid semi-interpenetrating silica network containing a large amount of quaternary ammonium groups was prepared by two sol–gel routes, in situ with a single precursor, N-trimethoxysilylpropyl-N, N, N-trimethylammonium chloride (TMSP), or ex situ mixing two … An Interpenetrating polymer network (IPN) is a polymer comprising two or more networks which are at least partially interlaced on a polymer scale but not covalently bonded to each other. The network cannot be separated unless chemical bonds are broken. The two or more networks can be envisioned … See more The first known IPN was a combination of phenol-formaldehyde resin with vulcanized natural rubber made by Jonas Aylsworth in 1914. However, this was before Staudinger's hypothesis on macromolecules … See more Molecular intermixing tends to broaden the glass transition regions of some IPN materials compared to their component polymers. This unique characteristic provides excellent mechanical damping properties over a wide range of temperatures and … See more Most IPNs do not interpenetrate completely on a molecular scale, but rather form small dispersed or bicontinuous phase morphologies with characteristic … See more IPNs have been used in automotive parts (including modern automotive paint), damping materials, medical devices, molding compounds, and in engineering plastics.
