A Mixed Covalent–Supramolecular Interpenetrated Copper–Phosphonate Network
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Zigzag Cu–bisphosphonate double strands are connected by dipyridyl linkers to two‐dimensional layers which are organized via hydrogen bonds into a three‐dimensional, two‐fold interpenetrated hydrogen‐bonded framework. A novel copper‐based coordination network [Cu(1,4‐DPB)(H2NBP)] was synthesized via a hydrothermal process using 1,4‐di(pyridin‐4‐yl ...

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT Hybrid CFRP/GFRP laminates offer an attractive balance between mechanical performance, damage tolerance, and cost efficiency. However, fiber bridging during mode I delamination increases crack‐growth resistance while masking the intrinsic fatigue behavior of the material. This study applies a traction–separation‐based superposition approach to

Potential of organogel‐based colloidal hydrogels for new cosmetic formulations
International Journal of Cosmetic Science, EarlyView.Colloidal hydrogels are formed by combining anionic, cationic, or nonionic surfactants with two oils of cosmetic interest: sweet almond oil and phytosqualane. These systems are obtained through hot emulsification followed by cooling, which leads to the aggregation of gel‐like particles.

Interpenetrating Polymer Networks
Angewandte Chemie International Edition in English, 1978AbstractBesides mechanical blending and copolymerization there is a third possible way in which two polymers can be combined. Each polymer forms its own network, while both networks interpenetrate each other. There are no covalent bonds between the polymers. Such interpenetrating networks have been synthesized sequentially (from polymer A and monomer B)

Interpenetrating Polymer Networks for Biological Applications
Biomaterials, Medical Devices, and Artificial Organs, 1979The use of a sequential polymerization method for preparing interpenetrating polymer networks with biocomatible surfaces has been studied. A hydrogel monomer was made to undergo polymerization with simultaneous cross-link formation, in the presence of a swollen thermoplastic elastomer heterophase block copolymer.

Interpenetrating Polymer Networks
Composite Interfaces, 2010Interpenetrating polymer networks (IPNs) are a new class of polymer blends in network form in which at least one component is polymerized and/or cross-linked in the immediate presence of the other. IPNs possess several interesting characteristics in comparison to normal polyblends, because the varied synthetic techniques yield IPNs of such diverse ...

Nomenclature of Interpenetrating Polymer Networks
Journal of Elastoplastics, 1973A nomenclature scheme for various types of interpenetrating polymer networks (IPN) based on morphology, topology, and method of synthesis is presented. In this scheme, IPN is the generic name of all polyblends of this type, regardless of their origin, as opposed to Sperling's recent classification of polyblends and graft copolymers, (Polymer Preprints,

Interpenetrating polymer networks
British Polymer Journal, 1985AbstractInterpenetrating polymer networks (IPNs) composed of two or more chemically distinct networks are not only intrinsically interesting as examples of macromolecular chemical topological isomerism but are in practice useful means of controlling mutual miscibility and phase morphology in crosslinked polymers.

Functional Semi‐Interpenetrating Polymer Networks
Macromolecular Rapid CommunicationsAbstractSemi‐interpenetrating polymer networks (SIPNs) have garnered significant interest due to their potential applications in self‐healing materials, drug delivery systems, electrolytes, functional membranes, smart gels and, toughing. SIPNs combine the characteristics of physical cross‐linking with advantageous chemical properties, offering broad ...
