｢Macromolecular Research｣ 목차 고분자 과학과 기술 제 30 권 6 호 2019년 12월 585 Enhancement of Thermal Conductivity of Poly methylmethacrylate Composites at Low Loading of Copper Nanowires Nhat Anh Thi Thieu, Minh Canh Vu, Eui Sung Lee, Vu Chi Doan, and Sung-Ryong Kim* Macromol. Res., 27, 1117 2019 The exceptionally long copper nanowires CuNWs with high aspect ratios were synthesized by the chemical reduction method and incorporated into the poly methylmethacrylate PMMA matrix to fabricate thermally conductive PMMA composites. The thermal conductivity of PMMAcomposites reached the highest value of 0.85 W/mK at 2.0 wt% of CuNW loading, which corresponds to an enhancement of more than 400% compared to that of the neat PMMA. The significant improvement of thermal conductivity is attributed to the well-dispersed CuNWs in the PMMA matrix and the high aspect ratio of CuNWs. The experimental results of thermal conductivity fitted well with the Agari model. Reconstituted Fib...

Res., 27, 1167 2019 A high-speed and low-cost fabrication process using intense pulsed light sintering of metal nanoparticles was studied. Silver, copper, and four different alloy composition of copper-silver core-shell type nanoparticles were synthesized. The power conversion efficiency PCE and lifetime of the organic photovoltaic OPV fabricated with sintered metal electrode were studied. The device performance of OPV can be maintained with the copper to silver alloy ratio of 2. The use of metal alloy electrode could reduce the price of the silver electrode down 33%.

Res., 27, 1185 2019 By adding diammonium phosphate DAP or aluminum diethyl phosphinate OP as flame retardants, flame retardancy of composites based on polypropylene and wood flour PP-WF improved significantly. A loading of 25 wt% DAP achieved a UL-94 V-0 rating as well as LOI value of 29%, which increased by 52.6% compared with that of the PP-WF composite alone. A 30 wt% OP loading provided a rating of UL-94 HB standard, and achieved LOI value of 28%. Meanwhile, the PP-WF composite without flame retardant, completely burned to the sample holder clamp with low LOI value 19% Thermal properties of the PP-WF composite with and without DAP and OP flame retard...

｢Macromolecular Research｣ 목차 고분자 과학과 기술 제 30 권 6 호 2019년 12월 591 Sulfonated Cross-Linked Poly ether ether ketone Films with Wrinkled StructuresPreparation and Vanadium Ions Permeability Abdul G. Al Lafi*, Reem Hasan, and Nedal Al-Kafri Macromol. Res., 27, 1239 2019 Sulfonation of ion irradiated poly ether ether ketone introduced a variety of wrinkling patterns on the surface of membranes. The wrinkles were controlled by varying the degree of sulfonation, cross-linking density and ion irradiation conditions. The membranes produced are promising for applications that require large-surface area and uniform surface patterning. They had a low permeability of vanadium ions, i.e. 1.5×10-7 cm2 min-1.
