Nylon membrane was modified by binding with polyhydroxyl-containing materials to increase its hydrophilicity and reduce its nonspecific interaction with proteins. The effect of binding hydrophilic materials on amount of ligand bound-Cibacron Blue F3GA (CBF) was investigated. Experimental data showed that the amount of CBF bound can be increased significantly after binding of hydrophilic materials. 展开更多

Developing high-performance electrode material with excellent flexibility still remains a big challenge.Herein,we report a simple interfacial polymerization method to fabricate interconnected polypyrrole(PPy)on a commercial nylon membrane(NM).Owing to the special and uniform microstructure of PPy/NM composite film,the free-standing electrode shows a maximal specific capacitance of 2911.4 mF cm^(-2) at 1mA cm^(-2) and superior capacitance retention of 88.7% after charge/discharge for 10,000 cycles.The symmetric all-solid supercapacitor assembled by the PPy/NM composite film exhibits outstanding cyclic stability(capacitance retention of 92.4% after 5000 cycles)and excellent flexibility(capacitance decreasing by 3.3% after bending around a rod with a diameter of 9mm for 1000 times).The results indicate that the PPy/NM composite film has great potential for high performance flexible supercapacitors. 展开更多

Microporous polyamide membrane (Nylon 6, PA) was modified by add hydrolysis and then coupled with hydroxyethyl cellulose (HEC) to amplify reactive groups and reduce nonspecific interaction with proteins. 1,6-Diaminohexane (DAH) as space arm and phenylalanine (Phe) as ligand were immobilized onto nylon membrane through the activation of s-triazine trichloride (CyCl3). The affinity membrane obtained can be used to adsorb γ-globulin specifically. The optimum conditions of preparing affinity membrane and adsorbing bovine γ-globulin were studied. 展开更多
