“…The oriented fibers were shown to have a conductivity of an order of magnitude higher than thin films made of the same material. Nanostructured colloids of conducting PANI were polymerized with SBP in the presence of chitosan (69). The morphology and stability of colloids produced using SBP was shown to be sensitive to both temperature and pH (70).…”

“…The template guided synthesis of polyaniline provided a unique approach for the control of polymerization of aniline to an electroactive polymer under mild conditions [9]. The use of toluenesulfonic acid produced mainly oblong particles whereas rodshaped particles were obtained using camphorsulfonic acid [141]. The use of toluenesulfonic acid produced mainly oblong particles whereas rodshaped particles were obtained using camphorsulfonic acid [141].…”

“…Polymers such as chitosan have been used as steric stabilizers while toluenesulfonic or camphorsulfonic acids have been used as doping agents during the enzymatic polymerization of aniline. The use of toluenesulfonic acid produced mainly oblong particles whereas rodshaped particles were obtained using camphorsulfonic acid [141]. Gu et al [142] also showed that sodium dodecyl sulfate denatured bovine serum albumin was a good template for the synthesis of conductive polyaniline polymers in the presence of horseradish peroxidase [142].…”

Enzyme application in polymer engineering is rapidly increasing and is set to revolutionize many industries. Given the multidisciplinary nature of this field, it has become clear that successful development of functional polymers entails tapping into advances in bioengineering, molecular biology, genetic engineering, chemical engineering, biochemistry, material science, nanotechnology, etc. This review summarizes the different strategies and reaction conditions that can influence the synthesis or modification of polymers. It is hoped that this review will provide scientists from different backgrounds with information on the different reaction engineering strategies for the successful development of functional polymers using oxidative enzymes.

“…Unlike SPS -templated polymerization, in dispersion polymerization the stabilizer is attached mainly to the surface of the colloids, providing water dispersability without doping the PANI. We later expanded the study of the enzymatic synthesis of colloids to other steric stabilizers such as 8.3 Synthesis of PANI in Template-Free, Dispersed and Micellar Media 193 poly( N -isopropylacrylamide) and chitosan [36,37] . Takamuku et al .…”

Since their discovery [1] , intrinsically conducting polymer s ( ICP s) have changed our way of thinking about polymers. With properties such as light weight, organic functionality, and distinctive electronic behavior, new applications were soon devised for these materials. Polyaniline ( PANI ) is one of the most interesting ICPs because of its chemical stability, tunable conductivity, and interesting electrochromic behavior [2] . This polymer is usually synthesized by chemical oxidation of the monomer in strong acidic media. Besides PANI, polythiophenes and polypyrrole are other important ICPs that have also been synthesized by oxidative polymerization. These polymers have been extensively used in several applications in the fi elds of organic electronics [3] , sensors [4] , actuators [5] , separation technologies [6] , and energy storage [7] , among others, and new applications for them are found continuously.Enzymatic polymerizations have become an interesting alternative route for polymer synthesis [8] . They are generally carried out under milder conditions than similar synthetic routes. Enzymes are natural catalysts which are non -toxic, biodegradable, energy effi cient and obtained from renewable resources. In this chapter, we review the different strategies that have been used for the enzymatic synthesis of PANI. Xu et al .[9] reviewed published work regarding enzymatic polymerization of aniline derivatives from its beginning until 2004. However, more recently, several groups have developed either new approaches for the enzymatic synthesis of PANI or different methods inspired by it. Indeed, the infl uence of the enzymatic synthesis of PANI can be seen in the development of several biocatalytic and biomimetic synthetic routes not only for the synthesis of PANI, but also for other important conductive polymers, such as polypyrrole ( PPy ) and poly(3,4 -ethylendioxythiophene) ( PEDOT ).
