| 中文摘要 | a polytetrafluoroethylene(ptfe) capillary ubbelohde viscometer was designed and constructed. the relative viscosities of aqueous solutions of a polyethylene oxide and a polyvinylpyrrolidone sample were carefully determined down to an extremely dilute concentration region. in comparison with the data obtained from the common glass capillary viscometer, slippage is believed to occur in the ptfe capillary due to its hydrophobic nature. while for the glass capillary viscometer, conventional viscous flow is operative and adsorption phenomena occur since both the solvent water and aqueous solution are wet and/or adsorbed onto the glass capillary surface due to the existence of hydroxyl groups on glass surface. the data were analyzed with a recently developed wall-effect theory and satisfactory results were obtained. |
