Extracts of fruits, herbs, vegetables, cereals, and other plant materials are rich in polyphenols. Polyphenols are rich in conjugated benzene rings with high electron density. Can the concentrated extract of these plants acts as a conductive substance to impart conductivity for textiles, papers or non-conducting polymers? If yes, to what extent would the conductivity of the treated polymers be? Can the treated polymers act as semiconductors?
Polyphenols are Anti Oxidant ( H+ ion doner) hence are coductive. Tannic Acid, Gallic Acid, Ellagic Acid are the name which belong to polyphenols category and have electrical conductivity.
Yes, polyphenolic substances present in the most immature fruits extract, The benefit of the plant as a means of defense, Associated with the protein portion of the enzyme.
Yes, one common example is Tannic acid. However, the electrical conductivity of biopolymer is related to its chemical structure as the electrical conductivity of organic molecule depends mainly on whether you are concerned with its proton conductivity or with its extended conjugation.
It is conducting in a solution - your proposition would require a solid I suppose - it would be intersting to research

I sincerly dobt his possibility. Aromatic conjugated polymers as polyaniline, polypyrrole, polythiophene (the best known examples) have a continuous conjugation, i.e. there is only one bond between the aromatic rings. In polyphenols even if they are chemically linked to each other there are two single bonds (an ether bond) between the two aromatic rings, i.e. the conugation is not continuous, there is not possibility of transferring the electron.
Please have a look at the following website: http://www.holdcroftgroup.com/picp.html
polyphenols are not conductive; conjugated benzene rings are not sufficient for conductvity, you need to have conjugation over several benzene ring in the chain.
to the question "What about polymerization of phenol? Is polyphenol produced from the polymerization conductive?" my statement is:
I don't think so as the link between the benzene rings is an ether bridge (Ph-O-Ph-O-...) which does not provide delocalisation (the polymerisation result should be called "polyphenyl ether")

Thanks to you all for your valuable answers. As seen, answers are either with or against! Practical research work will determine this issue.
