【摘要】 以平板流延法制备了液晶/高分子/冠醚/棕榈酸四元复合膜,探讨了膜的结构和K~+离子输送、透过性能,确认了以上四元复合膜中液晶连续相的存在。液晶微区的存在是载体扩散输送的有效介质。肯定了以冠醚、脂肪酸联合为载体时复合膜对K~+离子的透过性能,同时也测定了在磁场下的K~+离子主动输送,在磁场下液晶分子的有序排列可极大地提高K~+离子透过率,并研究了不同形状及性能的冠醚对透过速率的影响。更多还原

【Abstract】 The composite membranes of four compounds of liquid crystal/ polymer/crown ethers/fatty acid have been formed by fluidify development at plate. The membranes structure and their properties of transporting and penetrating K~+ are discussed. The presence of continuous phase of liquid crystal in above described.membranes and the effective medium of support diffusion, i.e. liquid crystal division are confirmed. The property of K~+ penetrating through the membranes is affirmed. The affect of active transportation of K~+ under the magnetic field is also measured and we found out that under the magnetic field the arrange in order of liquid crystal molecules can greatly increase the penetrating rate, as well as the influence of crown ethers with various shapes and properties on penetrating rate is discussed.更多还原
