Several functionalized benzo[1,2-b:3,4-b':5,6-d'']trithiophenes have been synthesized and characterized. The fully planar and highly electron-rich material shows great promise as the donor constituent in donor-acceptor type copolymers for use in organic electronics. As a proof of concept, a copolymer with the electron acceptor, 2,1,3-benzothiadiazole, has been prepared. Side-chain modifications...

Each film coating formulation and film forming polymer has an individual limiting maximum viscosity value for processability which depends on the type of nozzle and coater used, as well as on the batch size. In order to optimize efficiency and quality, knowledge of the formulation dependant viscosity curves is absolutely necessary. Fig. 1: Thermo Scientific HAAKE RotoVisco 1 rotational rheomete...

We present the first micromachined rotational electret power generator, linearized theoretical model of electret power generation, and novel method to produce uniformly charged electret. We also improved our previously developed [ I , 21 thin film Teflon AF 1601-S electret technology with respect to dielectric thickness, charge uniformity, and processability. In demonstration, our prototype pow...
