Description

一种疏水型磁化木的制备方法
技术领域
本发明涉及一种疏水型磁化木的制备方法。
背景技术
磁性NiFe2O4纳米粒子是一种性能优异的磁性纳米粒子，其具有较高的饱和磁化强度和较小的娇顽磁力，广泛的运用于磁记录材料、磁流体、催化剂和医药领域。通过水热法将无机纳米材料高效负载于木材表面来制备功能性无机纳米/木材新型无机-有机物复合材料，这不仅继承了木材天然的物理、化学、力学特性，而且因为无机纳米粒子的小尺寸效应和表面效应衍生出众多新的特殊性能，对木材的高附加值利用和功能化拓展具有重要的研究意义，为制备磁化木复合材料提供了一种新的方法和研究思路。
同时，由于木材是一种亲水性物质，其表面存在大量的羟基，使木材极易产生吸水膨胀、翘曲变形等情况，这极大地限制了木材的应用范围。通过对磁化木进行了疏水处理，在保证磁化木原有磁性不变的基础上在其表面构建了疏水膜层，实现了磁化木的由亲水性到疏水性的转变，从而制备的具有疏水性和磁性的双功能木材，极大的拓展了木材的使用范围。

(2)向反应容器内加入适量的NH3·H2O后使其混合溶液的pH值为9-12，反应温度为室温，反应时间为3～12h；
(3)将经步骤(2)处理后的木材于20～110℃条件下真空干燥1～48h，即可制得磁化木；
(4)将步骤(3)制得的磁化木在室温下浸入1H，1H，2H，2H-全氟癸基三甲氧基硅烷(FAS-17)乙醇溶液中磁力搅拌1-100h；
(5)将经过步骤(4)FAS-17改性的磁化木于20～110℃条件下真空干燥1～48h，即制备得到疏水型磁化木。
上述步骤(1)中Fe3+的来源是硝酸铁、氯化铁、硫酸铁中任何一种形式的三价铁盐，NI2+的来源是硝酸镍、氯化镍、硫酸镍中的任何一种含有镍离子的盐。
