Combining organic polymers with

While the intellectual importance of polyacetylene is undeniable, the technological importance is less so. The material is insoluble, brittle, and thus difficult to process. Recall that a key promise of electronic organic materials is to combine the facile synthesis and process-ability features of organic polymers with novel electronic properties. Polyacetylene does not quite meet the goal. 

In principle, every metal complex (or metal salt) can be incorporated into an organic polymer monomolecular or aggregated with the result of a solid composite material. Because of several hundred papers that have been published in this field, the following survey considers only few examples. The combination of organic polymers with included metal complexes olfers the advantage of preparing more flexible films with higher mechanical stability. In addition, polar polymers impress the activity in devices with metal complexes as active parts. 

Metal containing polyynes are multifunctional materials which combine the properties of organic polymers with those of metal centers coordinated to the organic moiety and are able to form nanotemplates, colloidal photonic crystals, multilayer capsules and hollow vesicles [127, 128], An example of a rod-like polymetallayne self-assembly in hollow nanorods has been recently reported [129] the computer simulations of the nanostructure show that the polymer chains are ordered in parallel lines that give rise to a tubular morphology rather unusual for these materials, but promising for sensor devices applications. 

The combination of organic polymers with inorganic oxides by means of the sol-gel process is one of the most convenient and attractive ways to prepare... 

MMMs consist of an inorganic or inorganic-organic hybrid material in the form of micro or nanoparticles (discrete phase) incorporated into a polymeric matrix. Use of two materials with different flux and selectivity provides the possibility to design a better gas separation membrane, allowing the synergistic combination of polymers, with easy processability and the superior gas-separation performance of inorganic materials. 

The presence of carbon—fluorine bonds in organic polymers is known to characteristically impart polymer stabiUty and solvent resistance. The poly(fluorosibcones) are siloxane polymers with fluorinated organic substituents bonded to siUcon. Poly(fluorosibcones) have unique appHcations resulting from the combination provided by fluorine substitution into a siloxane polymer stmcture (see Silicon compounds, silicones). 

Although not designed to control filtration, HEC may be effective as a filtration control agent in combination with other organic polymers in waters having salinities up to saturation. 

Microwave or radio frequencies above 1 MHz that are appHed to a gas under low pressure produce high energy electrons, which can interact with organic substrates in the vapor and soHd state to produce a wide variety of reactive intermediate species cations, anions, excited states, radicals, and ion radicals. These intermediates can combine or react with other substrates to form cross-linked polymer surfaces and cross-linked coatings or films (22,23,29). 

Properties. Hydroxypropylcellulose [9004-64-2] (HPC) is a thermoplastic, nonionic cellulose ether that is soluble in water and in many organic solvents. HPC combines organic solvent solubiUty, thermoplasticity, and surface activity with the aqueous thickening and stabilising properties characteristic of other water-soluble ceUulosic polymers described herein. Like the methylceUuloses, HPC exhibits a low critical solution temperature in water.
