In the above examples, which may be called simple colloids, a clear distinction can be made between the disperse phase and the dispersion medium. However, in network colloids this is hardly possible since both phases consist of interpenetrating networks, the elements of each being of colloidal dimensions. Porous solids, in which gas and solid networks interpenetrate, two-phase glasses (opal glasses), and many gels are examples of this category. [Pg.3]

Interpenetrating and Semi-Interpenetrating Polymer Networks The void space in the stmcture of the polymer network can be occupied by other molecules. When this space is occupied by other polymer network, interpenetrating or semi-interpenetrating polymer networks result. [Pg.189]

The p-quinol clathrate inclusion compounds are beautiful and early examples of solid-state catenation. In P-quinol each hydrogen-bonded network is single and three-dimensional two such networks interpenetrate, to use Powell s original term, but are linked neither by covalent nor by hydrogen bonding. We would describe them as being catenated. [Pg.122]

At some compositions and under some hydrolysis conditions, bicontinuous phases can be obtained (with the silica and polymer phases interpenetrating one another). The mechanism may be spinodal decomposition, occuning either before or after the polymerization. Since the two networks interpenetrate one another, the mechanical properties first exhibited by the material can be very peculiar. In a first deformation, the silica network would give a very high initial modulus, but once this structure is broken, additional deformation cycles would indicate much lower values of the modulus. [Pg.406]

The PtS network consists of equal numbers of tetrahedral and square-planar centers. Two such networks interpenetrate in the structure of [ Cu (tcp) Cu ]BF4-I7C6H5NO2 [Cu (tcp) = 5,10,15,20-tetrakis(4-cyano-phenyl)-21H,23H-porphine copper(II)]. The networks interpenetrate in an asymmetric fashion, i.e., the second net does not lie in the center of the channels and cavities of the first, but rather lies to one side. Attractive internet porphyrin... porphyrin interactions are the likely cause, and it produces larger channels and cavities, which contain large amounts of essentially liquid solvent, than would normally be expected. [Pg.737]

The existence of more than one type of network super-stracture for the same molecular building block represents supramolecular isomerism. Therefore, it is related to stractural isomerism at the molecular level. Supramolecular isomerism is the existence of different architectures (i.e., architectural isomerism) or superstructures. Polymorphism is a type of supramolecular isomerism but not vice versa. Supramolecular isomerism can be classified as structural (the same components result in different network superstructures), conformational (different conformations of a flexible molecule generate different, but often related, network architectures), catenane (the different maimer and degrees in which networks interpenetrate or interweave), and optical (chirai networks that... [Pg.971]

No significant examples of network interpenetration were found, analogous to the interpenetration known to obtain in ice VII and ice VIII. [Pg.149]

Within a singular framework, stiff networks are less able to respond to the local environment by adapting their molecular configuration than more flexible polymers. This means that, for the individual framework, a stiff polymer is more likely to be open and the nodes well dispersed. A flexible polymer will be able to pack more efficiently, even if no network interpenetration is taken into account. [Pg.162]

Network interpenetration is energetically favourable as it increases the van der Waals interactions between frameworks and therefore allows space to be packed more efficiently. Frameworks where the node-to-node distance is comparatively large compared to the width of the strut will have space for network interpenetration to occur. Those that have comparatively short struts may inhibit network interpenetration simply due to geometric space considerations. [Pg.162]

The flexibility of the network can also directly influence the degree of network interpenetration. CMPs with long flexible node-struts are able to respond to the local environment through bending of the strut and twisting around the node to allow individual frameworks to find space to pack efficiently in to. [Pg.162]
