Relation Between Charge Transport and the Number of Interconnected Lamellar Poly(3-Hexylthiophene) Crystals

Wang, Binghua; Chen, Jingbo; Shen, Changyu; Reiter, Günter; Zhang, Bin

We have investigated the lateral charge transport in a multilamellar network of crystalline structures of poly(3-hexylthiophene) (P3HT) embedded in a matrix of small crystallites and amorphous polymers resulting from crystallization at temperatures close to the melting point. Removing the matrix by an appropriate washing process allowed us to observe a…

Liquid Crystal Elastomer Waveguide Actuators

Kuenstler, Alexa S.; Kim, Hyunki; Hayward, Ryan C.

While most photomechanical materials developed to date have relied on free-space illumination to drive actuation, this strategy fails when direct line-of-site access is precluded. In this study, waveguided light is harnessed by liquid crystal elastomer (LCE) nanocomposites to drive actuation. Using photo-chemical reduction of gold salts to plasmonic nanoparticles, prescription…

Thermally Conductive and Electrically Insulating PVP/Boron Nitride Composite Films for Heat Spreader

Liu, Y.; Wang, N.; Ye, L.; Zehri, A.; Nylander, A.; Nkansah, A.; Lu, H.; Liu, J.

Thermally conductive materials with electrically insulating properties have been extensively investigated for thermal management of electronic devices. The combined properties of high thermal conductivity, structural stability, corrosion resistance and electric resistivity make hexagonal boron nitride (h-BN) a promising candidate for this purpose. Theoretical studies have revealed that h-BN has a
