Polymer Complexes Collector

Polymer complexes collector refers to the mixture of water-insoluble macro-molecular polymer and general oxide collector. Therefore, polymer complexes collector is characterized by water-soluble and good collecting performance. For example, two polymer complexes solutions are obtained when polyvinyl acetate (PVAC) is, respectively, mixed into laurylamine hydrochloride (LAHCL) and sodium dodecyl sulfonate (NaLS). The structure of PVAC can be expressed as follows  

It is reported that the molecule of LAHCL gets adsorbed on the hydrocarbon chain of PVAC via van der Waals force. 

The flotation results of magnetite using the above two polymer complexes collectors are given as follows  

It can be seen that the collecting performance of polymer complexes collector is relatively stronger.

NaLS-PVAC polymer complexes collector The mass ratio of NaLS to PVAC is 1 5. 

The flotation processes are characterized by wide flotation pH and no limit of PZC of mineral when the above two polymer complexes used as collector. 

Kozlowski et al. [20] presented the cyclodextrin polymers obtained by crosslinking P-CD with phtalic or 3-nitrophtalic anhydrides. It should be noted that molar mass fraction of the polymers over 100 kDa was obtained at higher temperatures, i.e. 65°C and 100°C. Preparation of polymers was carried out at concentration ratio P-CD NaH anhydrides equal to 1 7 7. For both polymers the similar fractions of molar masses were found. The high floatability of copper (II) obtained with the use of nonylphenol polyoxyethyl glycol ether as an non-anionic surfactant and P-CD polymers as complexation collector agent, show that the removal of metal ions decreases with increase of molecular mass of P-CD polymers linked by phtalic or 3-nitrophtalic anhydrides. For both derivatives of P-CD polymers with pH increase the... 

Most practical electrodes are a complex composite of powders composed of particles of the active material, a conductive diluent (usually carbon or metal powder), and a polymer binder to hold the mix together and bond the mix to a conductive current collector. Typically, a composite battery electrode has 30% porosity with a complex surface extending throughout the volume of the porous electrode. This yields a much greater surface area for reaction than the geometric area and lowers polarization. The pores of the electrode structures are filled with electrolyte. 

Electroluminescence from clay/polymer intercalation compound has been reported (287). Electroluminescent poly[2-methoxy-5-(2 -ethyl-hydroxy)-1,4-phenylenevinylene] was complexed with dimethyl dehydrogenated-tallow ammo-nium-montmorillonite. The product was fabricated as thin films by spin coating the suspension on ffO-coated glass substrate and subsequent deposition of A1 on the films as cathodes. Complexation with clay led to improved photostability and photoluminescence output. The absorption characteristics of dyes also have been utilized to prepare clay-dye hybrids as possible ultraviolet radiation collectors (288-290). 

To the best of the authors knowledge to date, it is still not possible to obtain a single continuous electrospun nanofiber, let alone one with a constant diameter. The best that has been achieved so far are randomly oriented nonwoven mats that are not so attractive for use as composite reinforcements. Attempts have been made to align electrospun nanofibers, however, due to the complex nature of the polymer jet trajectory, this is difficult. Most of the techniques employed use a collector moving or rotating at high speeds... 

The well known complexing properties of macrocyclic compounds towards metal ions have led to their incorporation into polymeric matrices. Polymer-supported crown ethers have many advantages, such as easy handling and recoverability when used for the removal of the toxic metal ions from the environment. Crown ether-, calixarene-, calixcrown- and cyclodextrin- based polymers have been recently receiving attention as the new polymers and may be processed into materials suitable as the extractant (solvent extraction), collector (ion flotation) or the ion carrier (transport across liquid membranes or ion selective electrodes).
