Conjugated polymers matrix

In the active layer of the device, positive carriers (holes) are transported through the conjugated polymer matrix, and negative carriers (electrons) are transported by hopping between fullerene molecules. Importantly, these two...

Some of the research focused on the nanosized loaded on conductive conjugated-polymer matrix. Mho et al. prepared V Oj/PANI composite films by a two-step electrochemical method and evaluated for their application in Li-ion batteries [64]. As a first step, the PANI film was... 

Ex-situ method can be defined as the method, where the nanomaterials are synthesized or mixed up within the pre-synthesized conjugated polymer matrix (Figure 12.5). 

The presence of conducting nanoparticles like metal in the conjugated polymer matrix has a catalytic influence in the sensing process. This catalytic effect is also responsible for the better response, better recovery, good... 

These conjugated polymers can be chemically and electrochemically reduced and reoxidized in a reversible manner. In all cases the charges on the polymer backbone must be compensated by ions from the reaction medium which are then incorporated into the polymer lattice. The rate of the doping process is dependent on the mobiHty of these charge compensating ions into and out of the polymer matrix.

Batteries. Many 7t-conjugated polymers can be reversibly oxidized or reduced. This has led to interest in these materials for charge-storage batteries, since polymers are lightweight compared to metallic electrodes and liquid electrolytes. Research on polymer batteries has focused on the use of polymers as both the electrode and electrolyte. Typical polymer electrolytes are formed from complexes between metal-ion salts and polar polymers such as poly(ethyleneoxide). The conductivity is low at room temperature due to the low mobility of cations through the polymer-matrix, and the batteries work more efficiendy when heated above the glass-transition temperature of the polymer. Advances in the development of polymer electrolytes have included polymers poly(ethylene oxide) intercalated into layered silicates (96). These solid-phase electrolytes exhibit significantly improved conductance at room temperature.
