研究了以硬脂酸、铝酸酯偶联剂改性和烷基酚醛树脂、丁腈橡胶为改性剂经表面原位组合化学方法处理的3种改性氢氧化铝,在液体石蜡和邻苯二甲酸二辛酯中体系粘度随不同改性方法、填充量、温度、烘干和放置时间等因素的变化。研究结果表明,3种改性的氢氧化铝在液体石蜡和邻苯二甲酸二辛酯中均比未改性的具有明显的降粘效果,在邻苯二甲酸二辛酯体系中都具有快速而稳定的抗沉降性。在液体石蜡体系中铝酸酯偶联剂改性的氢氧化铝的降粘效果最好。表面原位组合化学改性的氢氧化铝在邻苯二甲酸二辛酯中的降粘效果最好,且在上述2种体系中抗沉降性最好。它们敞开放置于空气中吸湿后,通过80℃烘干2~4h可恢复改性效果。 相似文献

The electronic band structures and band gap bowing parameters of InxGa1-xN are studied by the firstprinciples method based on the density functional theory. Calculations by employing both the Heyd-ScuseriaErnzerh of hybrid functional(HSE06) and the Perdew-Burke-Ernzerhof(PBE) one are performed. We found that the theoretical band gap bowing parameter is dependent significantly on the calculation method, especially on the exchange-correlation functional employed in the DFT calculations. The band gap of InxGa1-xN alloy decreases considerably when the In constituent x increases. It is the interactions of s–s and p–p orbitals between anions and cations that play significant roles in formatting the band gaps bowing. In general, the HSE06 hybrid functional could provide a good alternative to the PBE functional in calculating the band gap bowing parameters. 相似文献
