Facile approach to fabricate waterborne polyaniline nanocomposites with environmental benignity and high physical properties.

摘要: Waterborne polyaniline (PANI) dispersion has got extensive attention due to its environmental friendliness and good processability, whereas the storage stability mechanical property have been challenge for waterborne PANI composites. Here we prepare through chemical graft polymerisation of into epichlorohydrin modified poly (vinyl alcohol) (EPVA). In comparison with prepared physical blend in situ polymerisation, PANI-g-EPVA is greatly improved keeps stable one year. addition, as-prepared film displays more uniform smooth morphology, as well enhanced phase compatibility. homogeneously distributed EPVA matrix on nanoscale. different morphology at aniline content. The electrical conductivity corresponds 7.3 S/cm when only 30% incorporated composites, then increases up 20.83 S/cm further increase Simultaneously, tensile strength from 35 MPa 64 MPa. can be directly used conductive ink or coatings cellulose fibre paper flexible high property, which also suitable large scalable production.
