为满足塔河油田裂缝封堵要求,分别以丁腈橡胶(NBR)和氢化丁腈橡胶(HNBR)为基体,耐盐型亲水树脂和聚醚型聚氨酯预聚体作为混合吸水剂,加工出遇水膨胀橡胶(WSR),用粉碎机将其破碎成堵剂。研究了物理复合型和反应复合型亲水树脂对WSR的力... 为满足塔河油田裂缝封堵要求,分别以丁腈橡胶(NBR)和氢化丁腈橡胶(HNBR)为基体,耐盐型亲水树脂和聚醚型聚氨酯预聚体作为混合吸水剂,加工出遇水膨胀橡胶(WSR),用粉碎机将其破碎成堵剂。研究了物理复合型和反应复合型亲水树脂对WSR的力学性能与吸水膨胀行为的影响,基体对WSR的力学性能和遇水膨胀行为的影响,以及堵剂在塔河矿化水中吸水膨胀性能的规律。结果表明,反应复合型WSR在高矿化水膨胀过程中表现出高膨胀倍率和吸水剂微析出现象。以HNBR为基体的WSR在130℃、2.0×10~5 mg/L塔河矿化水中,表现出较高的体积膨胀倍率。 展开更多

Organic electroluminescent device,also known as organic light-emitting diode (OLED),is a kind of solid state light emitting device by carrier injection which can directly transform electrical energy into luminous energy.Due to its low operating voltage,low energy consumption,high brightness,flexibility in the choice of materials and easy realization of full color display,OLED is the potential material both in the display and illumination fields.However,there is much scope to improve the efficiency,lifetime,and reduce the cost in mass production before OLEDs can replace traditional technology in some application fields.In this work,we report the oxygen plasma immersion ion implantation (PIII) to improve the surface oxygen ratio of ITO films for further increase of surface work function above the common treatment of O2 inductively coupled plasma (ICP).The ratio of oxygen content at the surface layer was improved to be much higher than by O2 ICP treatment.A further surface work function relative increase of 0.4e V above OICP sample and 0.4 eV above the as-prepared sample can be estimated by the peak relative shift in the X-ray photoelectron spectroscopy (XPS) diagram.Moreover,the XPS characterization was carried out at least 50 h after the PIII implantation to indicate that the surface modifying effects are stable.The variations of transparency and conductivity of the PIII treated ITO samples can be neglected. 展开更多
