Nanofillers in Pulp and Paper

The growing demand for pulp and paper industries has made a continual improvement in the engineering applications of pulp and paper, leading to the emergence of addition for different nanofillers with advanced properties. Nanofillers uses such as from natural resources- silica, nanocellulose, and from metal oxides or metal particles are implemented to increase the strength especially in tear resistance and other properties such as in tensile strength, physical properties, dimensional stability, and also on fire resistance. However, the increasing awareness on environment legislation and consumers highlights the importance of using natural, environmentally friendly, cost-effective has becoming a serious consideration in choosing and applying nanofillers in papers. The uses of natural fibers and nanoclay are nowadays positively increase in demand and trend due to the tendency of these materials, which are considered as a green material, to provide high tear strength and some barrier properties for water retention and dimensional expand. This chapter briefly discusses the recent literature and study on various nanofillers in paper, covering the nanofillers, including their properties and applications in paper industries. Furthermore, this review also considered the pros and cons of the chosen nanofillers when applying them in papers.
