Research Progress of Filler Engineering and New Fillers in Papermaking

Fillers are extensively used in the papermaking industry either to lower the manufacturing cost,or to improve the critical properties of paper and paperboard products.In recent years,filler engineering has become a research field with great significance,and the relevant re- search work has been generally focused on modification and improvement of inorganic fillers.The preparation technologies of engineering fill- ers including modification with hydrophobic/partly hydrophobic natural polymer deposit film,modification with water-soluble polymer,and modification with inorganic compound are now among the hot topics under investigation.Also,development of new fillers including fibrous fillers,starch based organic fillers,swelling sericite and other related types of fillers with specific desired properties has been proved to be of vital importance in papermaking applications.In this paper,the present status and emerging technologies of filler engineering and new fillers are reviewed,and the corresponding prospective applications are analyzed and presented.
