Computational analysis of tunneling conduction in piezoresistive carbon nanotube polymer composites
Autor: Wolfgang Klimm, Kawai Kwok
Publikováno v: Journal of Intelligent Material Systems and Structures. 34:928-943
Carbon nanotube polymer composites exhibit piezoresistivity that can be utilized for flexible strain sensors. Piezoresistive modeling is critical for improving sensor performance, but remains a challenging subject due to the complex CNT network micro

Electro-thermo-mechanical behavior of carbon nanopaper shape memory polymer composites
Autor: Kawai Kwok, Veli Bugra Ozdemir
Publikováno v: Journal of Intelligent Material Systems and Structures. 33:489-500
An electro-active composite based on carbon nanopaper (CNP) shape memory polymer (SMP) composite is proposed for actuating deployment of composite deployable structures. Carbon nanopaper shape memory composites are stimuli-responsive materials that c

Tunneling resistance model for piezoresistive carbon nanotube polymer composites
Autor: Wolfgang Klimm, Kawai Kwok
Publikováno v: Nanotechnology. 34(4)
Carbon nanotube (CNT) polymer composites exhibit outstanding electrical conductivity that enables a myriad of sensing and actuation applications. Highly sensitive strain sensors can be realized through piezoresistivity in which a resistance change is

Inflated Cone Experiment for High-Throughput Characterization of Time-Dependent Polymer Membranes
Autor: Veli Bugra Ozdemir, Kawai Kwok
Publikováno v: Journal of Applied Mechanics. 89
Long-term behavior of polymer membranes in the nonlinear regime is probed by strain histories under various stress levels. Current characterization methods for polymer membranes impose a uniform stress field and hence require a series of long-duratio

Interface Fracture Energy of Contact Layers in a Solid Oxide Cell Stack
Autor: Belma Talic, Henrik Lund Frandsen, Kawai Kwok, Li Han, Peter Vang Hendriksen
Publikováno v: Han, L, Talic, B, Kwok, K, Hendriksen, P V & Frandsen, H L 2020, ' Interface fracture energy of contact layers in a solid oxide cell stack ', Applied Energy Materials, vol. 3, no. 3, pp. 2372-2385 . https://doi.org/10.1021/acsaem.9b02026
A critical factor for improving the long-term stability/reliability of solid oxide cell stacks is ensuring good adhesion between the stack components. Specifically, ensuring strong adherence between the oxygen electrode and the interconnect is challe
