Electron transport and photoelectrical behavior of poly(N-vinylcarbazole)/Poly(3,4-ethylenedioxythiophene) composite honeycomb-patterned films
Macromolecular Research - Tập 24 - Trang 267-275 - 2016
Chitragara Basavaraja, Eun Jin Jo, Do Sung Huh
New type of poly(N-vinylcarbazole) (PVK) polymer nanocomposites were prepared by a solid-state polymerization of N-vinylcarbazole in the presence of different concentration (wt%) of poly(3,4-ethylenedioxythiophene) (PEDOT). The prepared PVK/PEDOT nanocomposites were characterized by using Fourier transform infrared (FTIR) and UV-vis spectra. The transmission electron microscopy (TEM) and X-diffrac...... hiện toàn bộ
Low-loss polymeric waveguides having large cores fabricated by hot embossing and micro-contact printing techniques
Macromolecular Research - Tập 12 - Trang 474-477 - 2004
Keun Byoung Yoon
We present simple, low-cost methods for the fabrication of polymeric waveguides that have large core sizes for use as optical interconnects. We have used both hot embossing and micro-contact printing techniques for the fabrication of multimode waveguides using the same materials. Rectangular and large-core (60 × 60 μm2) channels were readily prepared when using these methods. The dimensions of the...... hiện toàn bộ
Optimization of chondrogenic differentiation of human adipose tissue-derived stem cells on poly(L-lactide-co-ɛ-caprolactone) scaffolds
Macromolecular Research - Tập 20 Số 7 - Trang 709-714 - 2012
Jung, Youngmee, Kim, Sang-Hee, Kim, Sang-Heon, Kim, Young Ha, Rhie, Jong Won, Kim, Soo Hyun
Mechanical stimuli should enhance cartilaginous tissue formation in elastic mechano-active poly(L-lactide-co-ɛ-caprolactone) (PLCL) scaffolds similar to what is observed in the body. The conditions for stem cell differentiation are also crucial for cartilage tissue engineering. Here, we investigate cartilaginous tissue formation of human adipose-tissue derived stem cells (hASCs)/hybrid scaffold co...... hiện toàn bộ
Dual-Responsive Shape Memory and Thermally Reconfigurable Reduced Graphene Oxide-Vitrimer Composites
Macromolecular Research - - 2019

Radiation grafting of binary monomers for the preparation of organic/inorganic hybrid membrane for proton exchange membrane fuel cell application
Macromolecular Research - Tập 20 Số 9 - Trang 912-919 - 2012
Joon-Yong Sohn, Hae-Jun Sung, Junhwa Shin, Bum-Seok Ko, Ju‐Myung Song, Young Chang Nho
Preparation of new red perylene fluoroionophores containing azacrown and their ionophoric properties
Macromolecular Research - - 2007
Young-Min Jeon, Tai-Ho Lim, Jong-Gyu Kim, Myoung-Seon Gong
The physical properties of thermotropic side-chain triblock copolymers ofn-butyl acrylate and a comonomer with azobenzene group
Macromolecular Research - Tập 17 - Trang 313-318 - 2009
Kyung Sik Dan, Byoung Chul Kim, Yang-Kyoo Han
The side chain liquid crystal triblock copolymers (TBCs), which underwent phase transitions below their decomposition temperature, were prepared by copolymerization of poly(n-butyl acrylate) and a comonomer containing the mesogenic azobenzene group. The physical properties of TBCs in the distinctive transition temperature ranges were investigated in terms of the liquid crystal (LC) content in the ...... hiện toàn bộ
Dopa-Empowered Schiff Base Forming Alginate Hydrogel Glue for Rapid Hemostatic Control
Macromolecular Research - Tập 27 - Trang 119-125 - 2018
Chung Kil Song, Min-Kyoung Kim, Junghan Lee, Enkhzaya Davaa, Rengarajan Baskaran, Su-Geun Yang
In this study we prepared tissue-adhesive hemostatic glue and assessed hemostatic effects on hepatic bleeding animal model. Alginate was used as primary polymer for the fabrication of hemostatic glue, oxidized for the introduction of the tissue-adhesive Schiff base forming aldehyde and then encoded with mussel-inspired dopa. In addition, polyallylamine (PAA) was selected for as an intra-structurin...... hiện toàn bộ
Polypyrrole-coated woven fabric as a flexible surface-heating element
Macromolecular Research - Tập 11 - Trang 481-487 - 2003
Jun Young Lee, Dong Won Park, Jeong Ok Lim
Polypyrrole (PPy) was coated sequentially by chemical and electrochemical methods on a woven fabric, giving rise to a fabric having high electrical conductivity. We investigated the effects of the preparation conditions on the various properties of the resulting fabric. The PPy-coated fabric with optimum properties was obtained when it was prepared sequentially by chemical polymerization at the el...... hiện toàn bộ
Preparation of new polyelectrolyte/ silver nanocomposites and their humidity-sensitive properties
Macromolecular Research - Tập 16 - Trang 308-313 - 2008
Min-Su Park, Tae-Ho Lim, Young-Min Jeon, Jong-Gyu Kim, Myoung-Seon Gong, Sang-Woo Joo
A simple strategy was developed based on polyelectrolyte/silver nanocomposite to obtain humidity-sensitive membranes. The major component of a humid membrane is the polyTEAMPS/silver nanocomposite obtained by thermal heating the mixture of a polyelectrolyte and silver isopropylcarbamate complex. Humidity sensors prepared from polyTEAMPS/silver (w/w=100/0 and 100/6) nanocomposites had an average im...... hiện toàn bộ
