Surface polarity of the polymer

The interfacial tension between the various polymer phases in the composite latex particles is of paramount importance in determining their final morphology. Other factors, such as the mode of monomer addition, the surface polarity of the polymer particles, initiator type, surfactant type, the presence or absence of crosslinking of one or more of the polymer phases, and the presence of chain transfer agents will also strongly influence the final particle structure. In addition, a survey of methods used to characterize the composite latex particles has been given. 

The surface polarity of the polymer is responsible for the adhesion between the active polymer and the electrodes, which is an important factor in charge injection, and... 

The incorporation of 5 wt% of a different OMMT in rPET was evaluated [41]. To get a well-exfoliated structure, the surface polarities of the polymer matrix and OMMT should be matched [74, 75]. The ammonium cations in Cloisite 30B, lOA and 25A are more polar, while those in Cloisite 6A, 15A and 20A, containing two long alkyl groups, are nonpolar. Hence, Cloisite 3 OB, lOA and 25A revealed a strong interaction with PET chains. In these samples, the maximum level of delamination was found in samples containing Cloisite 25A and 30B.
