High Performance Polymers solution fabrication

One of major changes for high performance polymer nanocomposites is to optimize the processing of CNT-reinforced polymer nanocomposites with low costs. Four processing techniques are in common use to fabricate the CNT/polymer nanocomposites direct mixing, solution method, in situ polymerization, and melt compounding [26-35]. Among these... 

There are several major m ods reported for preparation of high performance polymer nanocompo-sites solution casting, in situ polymerization, and melt conpoimding [10-13]. Of these processing techniqnes, melt compounding has been accqjted as a simple and effective method, particularly from an indnstiial perspective, because this process makes it possible to fabricate high performance polymer nanocomposites at low cost and to fabricate large scale-up for conuneicial appUcation [14-16]. In addition, incorporation of very... 

Organic field effect transistor (OFET) devices have been fabricated from pBTTT polymer solutions and hole mobility values of up to 0.8cm /V s were reported in a nitrogen atmosphere. These values approach that of high performing evaporated small molecule devices and are comparable to amorphous silicon. In bottom gate, bottom-contact devices, in which the active semiconductor layer is the exposed top surface, the effect of different ambient conditions has been evaluated. Exposure to unpurified, ambient air in which the humidity is -50%, results in an initial increase in the off-current of the device. In filtered, low humidity air, transistor devices remain very stable over time.
