摘　　要：为了提高Cs0.33WO3粒子的分散性及其涂层的近红外遮蔽性能,对球磨和分散剂对粒子分散和近红外遮蔽性能的影响进行了研究,以聚乙烯醇(PVA)、聚乙烯醇缩丁醛(PVB)和聚乙烯吡咯烷酮(PVP)为成膜物质制备了Cs0.33WO3涂层。研究结果表明,球磨和分散剂聚乙二醇-400能够显著降低Cs0.33WO3粒子的平均粒度,提高Cs0.33WO3粒子分散稳定性。其中,PVA/Cs0.33WO3和PVP/Cs0.33WO3涂层均具有良好的可见光透过率和近红外遮蔽率,并且PVP/Cs0.33WO3涂层同时还具有最佳的附着强度。In order to obtain good dispersion of Cs0.33WO3 particles and improve their near-infrared（NIR）shielding efficiency,the influence of ball-milling and dispersant on the dispersion stability of Cs0.33WO3 particles and its near infrared shielding properties was investigated.The Cs0.33WO3 coating was prepared with polyvinyl alcohol（PVA）,polyvinyl butyral（PVB）and polyvinylpyrrolidone（PVP）as film former,respectively. The results indicated that ball-milling and polyethylene glycol-400 could decrease the particles size of Cs0.33WO3 and improve its dispersion stability.The coating of PVA/ Cs0.33WO3 and PVP/Cs0.33WO3 showed the best visible light transmittance and near-infrared shielding properties,while PVP/Cs0.33WO3 coating showed excellent adhesion.
