摘要:
以新鲜海带为原料，经盐酸酸化和NaOH溶液碱处理，利用真空冷冻干燥方法制备海带发泡缓冲材料，并对其结构和性能进行研究。结果表明：海带发泡缓冲材料呈致密的枝化结构，由薄壁构成开孔。当NaOH质量分数为 1.1%时 ，缓冲材料的密度（ ρ * ）、孔壁材料的密度（ ρ s ）和相对密度（ ρ */ρ s ）最小，分别为0.0449g/cm 3、 0.6483g/cm 3 和0.0693，而缓冲材料的平均孔径、初始弹性模量和压缩吸收能最大，分别为0.4 mm、0.15 MPa和 42.38 kJ/m 3。随着NaOH质量分数的增加，海带发泡缓冲材料的平均孔径减小， ρ*、 ρ s 和 ρ */ρ s 则增大，初始弹性模量先减小后略微增大，压缩吸收能呈减小趋势。因此当NaOH浓度为1.1%时，海带发泡缓冲材料的静态缓冲性能最好。
