摘　　要：通过控制尼龙6和ε-聚赖氨酸在三氟乙醇和水中的溶解量、三氟乙醇的浓度和混合顺序,以溶剂法实现尼龙6和ε-聚赖氨酸真溶液分散,然后经过旋转蒸发和真空干燥,制备得到不同ε-聚赖氨酸含量的尼龙6系列复合材料。利用热重分析仪和差示扫描量热仪考察商品尼龙6、ε-聚赖氨酸和系列样品的热性质,结果表明:通过溶剂法处理,提纯和重结晶商品尼龙6,尼龙6的结晶温度提高了9℃,熔点提高了7℃;ε-聚赖氨酸的加入影响了尼龙6的规整度,使尼龙6的熔点和结晶温度稍有变化,变化幅度小于3℃,不影响其加工性能。The dispersion of nylon 6(PA6)and ε-polylysine(ε-PL)solution was achieved by controlling the solubility of PA6 and ε-PL in trifluoroethanol and water,the concentration of trifluoroethanol and the mixing order,and then PA6 series composites with different ε-PL content were prepared by rotary evaporation and vacuum drying.The thermal properties of commercial PA6,ε-PL and a series of samples were investigated by thermal gravimetric analyzer and differential scanning calorimeter.The results showed that commercial PA6 was purified and recrystallized by solvent treatment,and the crystallization temperature of PA6 was increased by 9℃,and the melting point was increased by 7℃.The addition of ε-PL affected the regularity of PA6,so that the melting point and crystallization temperature of PA6 decreased slightly,but the decrease was less than 3℃,which did not affect its processing performance.
