“…The adverse effects of mineral additives, such as calcium carbonate and clay particles, on paper strength are well known (Bown 1985a(Bown , 1998Tanaka et al 2001;Li et al 2002). In general terms, such effects have been attributed to the fact that mineral particles at the surfaces of fibers can get in the way of potential bonding interactions between adjacent fibers.…”

“…Various authors have shown cases in which the addition of dry-strength additives to papermaking furnish has helped them to achieve the stated goal of the present article -to maintain strength properties with less reliance on virgin cellulosic fibers. For instance, dry-strength additives have made it possible to use higher levels of mineral products as fillers in paper (Fineman and Lindström 1985;Tanaka et al 2001;Brouillette et al 2010). Alternatively, the strength of products made from recycled furnish has been improved by such additives (Eichinger 1981;Gaspar 1982;Strazdins 1984;Hipple 1991;Pelton 2004;Mocchiutti et al 2006;Fatehi et al 2010).…”

“…When using a filler product that has a bulky composite structure, it can be easier to maintain the caliper at least as high as the required minimum value. Although, in general, a bulky type of filler tends to have a greater debonding effect on paper (Gill 1989), such effects can be at least partly compensated by use of cationic starch and other bonding agents at the wet end (Lindström and Florén 1984;Lindström et al 1985;Alince et al 1990;Tanaka et al 2001;Sang et al 2011), as well as application of size-press starch to the paper's surface (Gerli et al 2011).…”

Paper production requires large amounts of cellulosic fiber, whereas the world's forested lands and croplands have a finite capacity to supply such resources. To deal with likely future pressure on forest resources, as well as to hold down costs of materials, publications examined in the preparation of this review suggest that the paper industry will need to implement several concurrent strategies. In particular, the industry can be expected to view recycling as a central part of its activities. Basis weights of various paper-based products can be expected to decrease over the coming decades, and more of the fiber content will be replaced with fillers such as calcium carbonate. Such trends will place intense demands upon chemical-based strategies to enhance the bonding within paper and paperboard. Based on the literature, further progress in reducing the amount of new forest resources used to meet a given set of paper product requirements will require a combined approach, taking into account various fiber attributes, nanostructures, novel concepts in bond formation, and advances in the unit operations of papermaking.

“…Interestingly, we observed a sharp increase in stiffness (Young’s modulus reached 2.56 vs 1.02 GPa for the reference paper), which is surprising because stiffness otherwise typically has an inverse correlation with the content of mineral fillers. 23 , 24 …”

“…An increase in the fiber–fiber bonding degree is a common explanation for the increase in the tensile stiffness of papers when, for example, adding carboxy-methyl cellulose 28 or a formula of cationic starch with mineral fillers. 23 , 24 …”

Eco-friendly and cost-effective materials and processes to manufacture functional substrates are crucial to further advance the area of printed electronics. One potential key component in the printed electronics platform is an electrically functionalized paper, produced by simply mixing common cellulosic pulp fibers with high-performance electroactive materials. Herein, an electronic paper including nanographite has been prepared using a standardized and scalable papermaking technique. No retention aid was needed to achieve a conducting nanographite loading as high as 50 wt %. The spontaneous retention that provides the integrity and stability of the nanographite paper, likely originates partially from an observed water-stable adhesion of nanographite flakes onto the fiber surfaces. The resulting paper exhibits excellent electrical characteristics, such as an in-plane conductivity of 107 S/cm and an areal capacitance of 9.2 mF/cm 2 , and was explored as the back-electrode in printed electrochromic displays.
