Poly(3-hexylthiophene) wrapped carbon nanotube/poly(dimethylsiloxane) composites for use in finger-sensing piezoresistive pressure sensors

Jihun Hwang, +6 more
- 01 Jan 2011 - 
TL;DR: A piezoresistive composite using multi-walled carbon nanotubes (MWCNTs) as conductive filler and polydimethylsiloxane (PDMS) as a polymer matrix, which operated in the extremely small pressure range required for finger-sensing, was fabricated in this paper.
Journal ArticleDOI

Complementary Absorbing Star-Shaped Small Molecules for the Preparation of Ternary Cascade Energy Structures in Organic Photovoltaic Cells

Hyojung Cha, +9 more
- 25 Mar 2013 - 
TL;DR: In this paper, two anthracene-based star-shaped conjugated small molecules are used as electron-cascade donor materials by incorporating them into organic photovoltaic cells.
Journal ArticleDOI

Effects of morphology on toughening of tetrafunctional epoxy resins with poly(ether imide)

J.B. Cho, +4 more
- 01 Jan 1993 - 
TL;DR: In this article, the effects of morphology on the fracture toughness of modified epoxy resins were investigated and the co-continuous structure and morphology of the PEI spherical domain dispersed in the epoxy matrix were obtained.
Journal ArticleDOI

Effects of direct solvent exposure on the nanoscale morphologies and electrical characteristics of PCBM-based transistors and photovoltaics

Sooji Nam, +6 more
- 28 Feb 2012 - 
TL;DR: In this paper, the effects of direct solvent exposure on the properties of [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) films and poly(3-hexylthiophene) (P3HT)/PCBM blend films employed as active layers in, respectively, organic field effect transistors (OFETs) and organic photovoltaics (OPVs).
Journal ArticleDOI

Solvent additive to achieve highly ordered nanostructural semicrystalline DPP copolymers: toward a high charge carrier mobility.

Tae Kyu An, +11 more
- 01 Dec 2013 - 
TL;DR: A facile spin-coating method in which a small percentage of the solvent additive, 1-chloronaphthalene (CN), is found to increase the drying time during film deposition, is reported.
