  Preparation of polymer/LDH nanocomposite by UV-initiated photopolymerization of acrylate through photoinitiator-modified LDH precursor

  摘要：

  The exfoliated polymer/layered double hydroxide (LDH) nanocomposite by UV-initiated photopolymerization of acrylate systems through an Irgacure 2959-modified LDH precursor (LDH-2959) as a photoinitiator complex was prepared. The LDH-2959 was obtained by the esterification of 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure 2959) with thioglycolic acid, following by the addition reaction with 3-(2,3-epoxypropoxy)propyltrimethoxysilane (KH-560), finally intercalation into the sodium dodecyl sulfate-modified LDH. For comparison, the intercalated polymer/LDH nanocomposite was obtained with additive Irgacure 2959 addition. From the X-ray diffraction (XRD) measurements and HR-TEM observations, the LDH lost the ordered stacking-structure and well dispersed in the polymer matrix at 5 wt% LDH-2959 loading. The glass transition temperature of UV-cured exfoliated nanocomposites increased to 64 degrees C from 55 degrees C of pure polymer without LDH addition. The tensile strength was improved from 10.1 MPa to 25.2 MPa, as well the Persoz hardness enhanced greatly, while the elongation at break remained an acceptable level. (C) 2010 Elsevier Ltd.

  乙氧基硅烷改性的多功能聚合光引发剂通过溶胶-凝胶法引发的紫外线辐照固化的有机-无机杂化纳米复合材料

  摘要：

  紫外线固化的有机-无机杂化纳米复合材料（nano-Si-m-PI）是通过乙氧基硅烷改性的多功能低聚光引发剂（Si-m-PI）引发的丙烯酸树脂的光聚合制备的。进行2-羟基-4'-（2-羟基乙氧基）-2-甲基苯乙酮（Irgacure 2959）与巯基乙酸的酯化反应，然后与二季戊四醇六丙烯酸酯然后进行3-氨基丙基三乙氧基硅烷进行加成反应以制备Si-m ‐PI。Si-m-PI表现出与Irgacure 2959相似的UV吸收和摩尔消光系数。通过photo-DSC分析进行的光引发活性研究表明，Si-m-PI在最高峰（R p max）和峰值处具有较高的光聚合速率。最终不饱和转化率（Pf）在固化的杂化膜中。从扫描电子显微镜（SEM）观察，SiO 2纳米颗粒均匀地分散在形成的Nano-Si-m-PI中，而纳米颗粒的聚集发生在nano-Irg中，这是通过Irgacure引发的丙烯酸树脂的光聚合制备的2959年
