Talk:Polyaniline

Polyaniline and conductive Polymer
Dear "materialscientist". Please explain what was wrong with my editing of these two subjects which you mainly undid a short while after I edited. I trust my updating was correct (e.g., the use of polyaniline dispersions in printed circuit board manufacturing is widespread). Moreover, the article which I cited (http://www.mdpi.com/2073-4360/2/4/786/) has a high relevance for the understanding of properties and applications of Polyaniline (and conductive polymers in general). There are many other citations in these 2 articles which do not necessarily represent a correct description for Polyaniline / conductive polymers, and even those which I do not agree to, I do not remove them; that would be scientifically unfair and biased. Please incorporate the articvle reference again to offer the readers the chance to build their own opinion. 80.187.110.107 (talk) 12:47, 3 January 2011 (UTC)


 * The edits made by 80.187.110.107 appear to have merit except for the deletion of reference to the Li 2006 study which is unexplained in the edit summary. The references cited should be respected. This user should get a user account and should report possible conflicts of interest (for example being an active researcher in the field). The edit made by Materialscientist appears sloppy, it contains much more than just deleting the reference? — Preceding unsigned comment added by V8rik (talk • contribs)
 * This discussion was continued at Talk:Conductive polymer. In short, an editor (likely on a floating IP) was promoting addition of a new theory based on unreliable (for such claims) source, presenting a recent primary research article as a review.

More edits, April 2012
The article was partly a vehicle to support the cause of PProctor and others who often complain about the Nobel prize that they should have gotten, it seems instead of others for the conductive polymers. Their method is to build up a "history" section that tries to diminish the work of McDiarmid and Heeger by highlighting the fact that many conductive polymers and organic materials were known in the early 60's and 50's. The point of this kind of correcting history essay is just lost on most readers who just want to read about polyaniline. So I removed the articles to polypyrrole and polyacetylene (except the general reviews to conductive polymers). Otherwise the article does not discuss the chemical structure or degree of protonation very much. A lot of the article was about applications, but I have not been able to identify any. We really need to address the structural and chemical aspects of polyaniline in this article.--Smokefoot (talk) 13:04, 16 April 2012 (UTC)

Excised content to be re-considered
Wikipedia has two guidelines that apply to the material below. Conflict of interest WP:COI and WP:SECONDARY.--Smokefoot (talk) 14:39, 11 February 2018 (UTC)

Since the second half of 70s, J. J. Langer has begun systematic research on electrical properties at Organic Semiconductor Laboratory (UAM Poznań, Poland). Subsequent to his investigation of other highly-conductive organic materials, MacDiarmid demonstrated the conductive states of polyaniline which arose upon protonic doping of the emeraldine form of polyaniline. Conductive polymers such as polyaniline remain of widespread interest, providing an opportunity to address fundamental issues of importance to condensed matter physics, including, for example, the metal-insulator transition, the Peierls Instability and quantum decoherence, the light emission, including SRS LED and random laser electrically powered.

. The different colors, charges and conformations of the multiple oxidation states also make the material promising for applications such as actuators, supercapacitors and electrochromics. Although polyaniline has been historically considered as a battery material, its intrinsic pseudocapacitive behavior has shifted the energy storage potential to supercapacitors. Polyaniline is, in fact, the most common conductive polymer for the fabrication of supercapacitors. An interesting feature of polyaniline, as well as other conducting polymers, is the versatility in manufacturing electrically conducting yarns, antistatic coatings, electromagnetic shielding, and flexible electrodes.

Polyaniline an attractive for acid/base chemical vapor sensors, supercapacitors and biosensors

Attractive fields for current and potential utilization of polyaniline is in antistatics, charge dissipation or electrostatic dispersive (ESD) coatings and blends, electromagnetic interference shielding (EMI), anticorrosive coatings, hole injection layers, transparent conductors, indium tin oxide replacements, actuators, chemical vapor and solution based sensors, electrochromic coatings (for color change windows, mirrors etc.), PEDOT-PSS replacements, toxic metal recovery, catalysis, fuel cells and active electronic components such as for non-volatile memory.

Start of Process section
The synthesis of polyaniline nanostructures is facile.[13]

The definition of facile is "(especially of a theory or argument) appearing neat and comprehensive only by ignoring the true complexities of an issue; superficial." How the synthesis of polyaniline appears, or seems to be, is subjective and irrelevant. It sounds like someone copied and pasted the lead sentence of one paragraph of a research paper describing the process. It works as a lead sentence, as presumably it would be followed by enumeration and explanation of the "true complexities". As a standalone sentence, however, it's vacuous.

Using surfactant dopants, the polyaniline can be made dispersible and hence useful for practical applications. Bulk synthesis of polyaniline nanofibers, which has been researched extensively.[14]

This is a broad generalization, which again sounds excised from more substantive material. Why are we talking about applications in a section headed "Process"? The second sentence isn't a sentence at all.
