Special Issue Information

Dear Colleagues,

I am glad to invite you into this Special Issue of Polymers, entitled ‘’The Synthesis and Application of Fluorescent Polymers, Conjugated Polymers, and Conducting Polymers’’. Over decades, electroactive polymers, including fluorescent polymers, conjugated polymers, and conducting polymers, have unveiled their unique characteristics, providing us with hope that they might replace heavy, rigid, and precious metals and inorganic materials in the traditional application fields. Some successful stories of the early electroactive polymers can be found in the areas of light emitting diodes and polymer solar cells. As we are experiencing new rapidly changing and diversified environments, the application area of polymers is concurrently corresponding to the needs of the traditional field. The emerging areas of polymers are not only cover the conventional fields but also cover the biomedical, energy, optoelectronics, nanotechnology, agricultural, and military areas. This Special Issue of Polymers aims to deliver readers superb polymers of conjugated polymers, fluorescent polymers, and conducting polymers that can be niche candidates for advanced fields (as shown in the Keywords below). I hope this Special Issue can enhance your professional career, by providing you and your colleagues with innovations in science, technology and engineering.

Core/shell pigments allow for the combination of the active anti-corrosion effect of the shell and the barrier effect of the core. This makes it possible to obtain anti-corrosion pigments, with a high—protective effect and low toxicity. Thus, the need for a comprehensive study of the properties of these pigments grows more urgent, before their application to paints and varnishes. The hiding power of core/shell pigments comes close to the one of pure polyaniline (PANi), when the PANi content in the pigment reaches 50 wt.%, with sulfuric and phosphoric acids used as dopants. This paper, also, shows that the blackness value of core/shell pigments with 10 wt.% PANi is around 35 and constant; for pure PANi, their blackness value is 40. When PANi content is 5 wt.%, kaolin-based pigment shows the lowest blackness, which happens due to a generally higher whiteness of kaolin. However, when the PANi content surpasses 10 wt.%, there seems to be no influence on the blackness of the core/shell pigments. The core/shell pigment with a 20 wt.% PANi is, optically, identical to a black-iron-oxide pigment. An increase in the PANi content of the core/shell pigment leads to an increase in the oil absorption of the samples. It was found that the dispersion process would be the most energy efficient for core/shell pigments, containing kaolin and talc as a core. Full article

Secondary dopants and the doping methods were identified for increasing the electrical conductivity of a highly processable and a primarily doped polyaniline dinonylnaphthalene sulfonic acid (PANI-DNNSA). The secondary doping was carried out using film, solution, and vapor doping methods. The doping methods and functional groups of secondary dopants were observed to play a critical role for inducing electrical characteristics of polyaniline. When secondary film doping method and p-toluenesulfonic acid were used, the electrical conductivity of the secondary doped polyaniline was measured to be increased from 0.16 to 334 S/cm. A novel vapor annealing doping method was developed to incorporate secondary dopants into solution cast polyaniline films. Full article

Metalla-ynes and poly(metalla-ynes) have emerged as unique molecular scaffolds with fascinating structural features and intriguing photo-luminescence (PL) properties.

Metalla-ynes and poly(metalla-ynes) have emerged as unique molecular scaffolds with fascinating structural features and intriguing photo-luminescence (PL) properties. Their rigid-rod conducting backbone with tunable photo-physical properties has generated immense research interests for the design and development of application-oriented functional materials. Introducing a second d- or f-block metal fragment in the main-chain or side-chain of a metalla-yne and poly(metalla-yne) was found to further modulate the underlying features/properties. This review focuses on the photo-physical properties and opto-electronic (O-E) applications of heterometal grafted metalla-ynes and poly(metalla-ynes). Full article
