In this thesis, we study the application of nano-starch in ordinary sizing starch was replaced by nano-starch as surface sizing in paper surface sizing, and its impact on paper properties was examined. It includes the study of Nano-starch, its influence on the performance of the sizing and on paper properties as sizing agents. The experimental data showed that the viscosity of the nano-starch solution was moderate. And the viscosity grown slow with the increase of concentration. JN and sodium dihydrogen phosphate both improved nano-starch solution viscosity. The effect of JN is more than sodium dihydrogen phosphate. When conventional surface sizing starch was replaced by Nano-starch, the physical properties of the paper, such as the tightness, burst index, breaking length, tear index, folding degree, sizing degree, have been greatly improved. And in comprehensive consideration, the best ratio between conventional surface sizing starch and Nano-starch was 6:2. The deposition properties of Nano- starch was good.
