Thermal behavior and fi re performance of nylon-6,6 fabric modi fi ed with acrylamide by photografting
Our previous study shows that surface photografting modi fi cation with maleic anhydride followed by
reacting with triethanolamine can improve the fl ame retardancy of nylon-6,6 fabric. In this study,
acrylamide was used as a grafting monomer to improve the fl ame retardancy of nylon-6,6 fabric. The
effects of monomer conce...

Novel benzo[1,2-b:4,5-b’]dithiophene-benzothiadiazole derivatives with variable side chains for high performance solar cells
Low band gap copolymers were prepared by incorporating thiophene modified benzo[1,2-b:4,5-b’]dithiophene and alkyloxy or fluorine modified benzothiadiazole as donor and accepter units. These copolymers showed desired deep HOMO and LUMO levels allowing the high Voc and Jsc. PCEs of over 6% are demonstrated in solar cell studies indicating their promising photovoltaic application as donor mate...

Effect of substituents on electronic properties, thin film structure and device performance of dithienothiophene-phenylene cooligomers
Dithienothiophene-phenylene cooligomers with n-hexyloxy or n-dodecyloxy substituents have been synthesized and compared to the previously reported unsubstituted parent compound. The effect of substituents on the thermal, electronic, optical. thin film structure and field-effect transistor (OFET) properties was investigated. Structural phase transitions from highly-ordered nanocrystalline to l...

Hypochlorite treatment on thin film composite RO membrane to improve boron removal performance
Controlled hypochlorite treatment was conducted on three commercial RO membranes to improve their boron removal performance. The effects of hypochlorite treatment on membrane performance, including permeate flux, NaCl rejection as well as boron removal were investigated. The effect of pH of feed water on both original and chlorinated membranes was also investigated. In order to better understand t...

Dependence of material quality on performance of flexible transparent conducting films with single-walled carbon nanotubes
Several single-walled carbon nanotubes (SWCNTs) prepared by different methods have been used to investigate the material dependence on the optimal film performance of flexible transparent conducting films. The nanotubes were dispersed in water with sodium dodecyl sulfonate by sonication. These SWCNT solutions were then sprayed onto the polyethylene terephthalate substrate by a spray coater to form...

Synthesis of Novel High-Performance Polymers via Pd-Catalyzed Amination of Dibromoarenes with Primary Aromatic Diamines.
A series of novel polymers have been obtained by the condensation polymerization of different dibromoarenes with different primary aromatic diamines via palladium-catalyzed aryl amination reaction. The structures of polymers are characterized by means of FT-IR, H NMR spectroscopy, and elemental analysis; the results show an agreement with the proposed structure. DSC and TG measurements show that...

57. Growth of Carbon Nanotubes on Clay: Unique Nanostructured Filler for High-Performance Polymer Nanocomposites. W.D. Zhang*, I.Y. Phang, T.X. Liu*. Adv. Mater. 18(1), 73-77, 2006.
Carbon nanotubes (CNTs) have been grown on the Fe-modified montmorillonite (clay) by chemical vapor deposition and the as-prepared CNTs-clay hybrid, without any further purification, was directly incorporated into nylon-6 (PA6) by melt-blending. The intercalation of the clay by Fe2O3 was further delaminated to well-separated nanoclay platelets by the growth of CNTs on them, thus forming a th...

Synthesis and Characterization of Novel Blood-Compatible Soluble Chemically Cross-Linked Polyurethanes with Excellent Mechanical Performance for Biomedical Applications.
A controlled cross-linking polymerization system was designed, and soluble chemically cross-linked polyurethane was synthesized using laurylamine, n-octylamine, n-pentylamine, and ethylenediamine chain extenders. The mechanical analysis showed that the polyurethane materials synthesized in this paper have very excellent mechanical properties with a breaking elongation of 1914% and a tensile streng...
