摘　　要：以海藻酸钠(SA)为基体,盱眙凹凸棒石(AT)为无机增强材料,采用溶液共混法制备了海藻酸钠/凹凸棒石复合材料。力学性能试验结果表明,当凹凸棒石用量为海藻酸钠质量的2.5%和甘油用量为海藻酸钠质量的3%时,海藻酸钠/凹凸棒石复合材料的力学性能较好。FTIR和SEM测试结果表明,复合材料中海藻酸钠和凹凸棒石之间存在强烈的相互作用和良好的相容性,两者共混明显改善了复合材料的力学性能。The attapulgite（ AT）were dispersed into sodium alginate（ SA）matrix to get sodium alginate/attapulgite composites through blending method with different composition. The mechanical properties show that when the amount of attapulgite and glycerine were 2. 5% and 3%,respectively,compared to so-dium alginate,the mechanical properties of the sodium alginate/attapulgite composites were best. The composites were characterized by FTIR and SEM. The results indicate that the FTIR characteristic peaks of sodium alginate/attapulgite composites appear when introducing attapulgite,and the mechanical per-formance of blend films is improved due to the strong interaction between sodium alginate and attapulgite.
