技術摘要 / Our Technology: |
本發明係應用幾何分散技術(Geometric Inhomogeneity Factor,GIF),以高深寬比之片狀或層狀黏土阻隔奈米顏料顆粒的聚集,達到均勻分散顏料的效果,使所得到的奈米顏料可有效分散於有機溶劑與水之母液中,並有效防止其再度聚集,維持黏度變化之穩定性。
A method for dispersing a pigment in a solvent comprises mixing the pigment in a nanoscale with clay in a layered or platelet form and mixing the resultant mixture with the solvent. The method is based on geometric inhomogeneity and mutually exclusive aggregation. The layered or platelet clay having a high aspect ratio is provided to hinder aggregation of the pigment nanoparticles. The pigment nanoparticles can be stably dispersed in a matrix containing an organic solvent and water without aggregation again.
