纳米改性内外墙涂料

一．技术名称纳米改性内外墙涂料 一、成果简介纳米粉体作为纳米科技的重要组成部分，其制备过程正在不断成熟，但如何应用于传统产业的提升是当前广泛关注的研究课题。据统计，我国的涂料产量已位居世界前四位，但涂料行业的问题仍然十分突出。目前，国内建筑涂料普遍存在开罐效果差、贮存稳定性不好、耐擦洗性能较差、外墙涂料抗污染能力不高、易分层、易脱落、粉化、褪色、老化等缺陷，这些都急待克服解决。因此，将纳米材料应用于建筑涂料的改性研究，提高其技术含量，势在必行。

The Bisphosphonate Clodronate Modifying Hydroxyapatite Bioceramics for Bone Scaffold

To investigate the efficiency of clodronate modifying HA bioceramics,and to evaluate the effect of clodronate modifying HA bioceramics on the cells in vitro,clodronate modified the porous HA bioceramics for bone scaffold by chelation .The outermost layer of the specimens was analyzd by XPS and FI-IR ,The depth profile was investigated by the argon-ion sputtering method.The cell culture test was conducted using MC3T3-E1 osteoblastic cells,The cells were inoculated and cultured on the scaffolds.Morphological observation of the cells,MTT test and ALP activity test evaluated the cell attachment ,proliferation and activity on the scaffolds.The cell culture test in cell quantity and morphology indicated active proliferation of the cells on the scaffolds.The ALP activity of the cells cultured for 3d and 7d on clodronate-HA bioceramics was slightly higher than that on HA bioceramics ,but the difference was not signifcant,This result indicated that clodronate-HA bioeramics had favorable cytocompatibility to be used as bone scaffold with potential ability to improve asteogensis.
