Poly(n‐undecyl isocyanate) (PUDIC)/n‐dodecylbenzenesulfonic acid (DBSA)‐doped polyaniline (PANIDBSA) polyblend was prepared and the effect of the H‐bonding between these two polymers on the compatibility, conjugation chain length of PANIDBSA, and helixity of PUDIC in the polyblend system were studied. The monomer and polymer were characterized by NMR spectra and the polyblend was analyzed by FTIR,...
A nanotubular polyaniline (PANINT) was prepared from a simple emulsified polymerization method without oil solvent present. A mechanism of the formation of the nano-fibers/tubes was proposed to show that it started with the connecting arrangement of the neighboring anilinium micelles before and during polymerization, which resulted in the formation of the intermediate morphology of centipedes converting...
We propose a complete self-defined empirical large-signal model, particularly including the noise characteristics, for the enhancement-mode AlGaAs/InGaAs pHEMTs. This model achieves the excellent fitting of the dc I-V and microwave performance by considering the different contribution of the drain-to-source impedance (R ds ) between dc and rf measurement. In addition, for a full perdition...
