“…The idea is to neutralize DCS by using something relatively inexpensive, on a mass basis. Benefits to the performance of retention aids following the use of scavengers to at least partly neutralize the DCS have been reported (Auhorn and Melzer 1979;Chung et al 1993;Glittenberg et al 1994;Näsman et al 1998;Zhang et al 2007Zhang et al , 2009Liu et al 2010;Ni et al 2011). Similarly, significant improvements in drainage rates (Auhorn and Melzer 1979;Linhart et al 1987;Miao et al 2006;Liu et al 2010), and sizing performance (Li et al 2002b;Hu et al 2004;Chen et al 2012a,b) have been reported following the use of high-charge cationic additives.…”

“…Studies have shown that peroxide bleaching of mechanical pulp can greatly increase the cationic demand of the corresponding process water (Nyström et al 1993;Thornton et al 1993;Sundberg et al 2000a;Bräuer et al 2001;He et al 2004;Pranovich et al 2005;Mou and Qin 2006;Miao et al 2006;Ni et al 2011;Pruszynski et al 2011). As will be discussed later in more detail, the charge demand contribution can mainly be attributed to the demethylation of uronic groups in pectins, giving rise to solubilization and release of the corresponding pectic acids or polygalacturonic acids (PGAs) (Sundberg et al 1993(Sundberg et al , 1994a(Sundberg et al , 2000aPranovich et al 2003).…”

“…Numerous published articles have documented the presence and consequences of DCS in papermaking process systems (see, for instance Holmbom and Sundberg 2003;Sjöström et al 2006;Ni et al 2011, Hu et al 2004Chen et al 2012a,b). In order to provide an introduction to the subject, this section will review publications that deal with charge demand in general, without reference to different components of DCS.…”

“…There are many reports documenting such adverse effects (Auhorn and Melzer 1979;Pelton et al 1980a;Ström et al 1982;Alince 1987;Nurmi and Eklund 2000;Reid and Ricard 2000;Polverari et al 2001;Zhang et al 2007;Ordonez et al 2009;Ni et al 2011;Pruszynski et al 2011). The decrease in effectiveness of cationic retention aids in such situations has been attributed to formation of polyelectrolyte complexes between cPAM and DCS (Mikkonen and Eklund 1998;Nurmi et al 2004).…”

“…Greater deposition of colloidal matter onto the wetted surfaces of the paper machine can take place, especially if the colloidal matter remains within the stock system for an extended time before it is retained (Allen 1980;Petander et al 1998;Hubbe et al 2006). Adverse effects of DCS on sizing, wet-strength treatments, and other paper properties have been reported (Auhorn and Melzer 1979;Sjöström et al 2006;Ni et al 2011).…”

Dissolved and colloidal substances (DCS) in the process waters of paper machine systems can interfere with the retention of fine particles, retard the drainage of water from the wet web, and generally hurt the intended functions of various polyelectrolytes that are added to the process. This review considers publications that have attempted to characterize the nature and effects of different DCS fractions, in addition to some of the ways that paper technologists have attempted to overcome related problems. The consequences of DCS in a paper machine system can be traced to their ability to form complexes with various polyelectrolytes. Such tendencies can be understood based on a relatively strong complexing ability of multivalent materials, depending on the macromolecular size and charge density. Continuing research is needed to more fully understand the different contributions to cationic demand in various paper machine systems and to find more efficient means of dealing with DCS.

Herein, a fully paper‐based all‐solid‐state supercapacitor with functionalized cellulose paper as electrodes, carboxymethyl cellulose gel as solid electrolyte and cellulose paper as separator was fabricated. The electrode was fabricated by a conventional papermaking process with silver‐modified fibers and graphene oxide (GO)‐modified fibers followed by reduction of GO. The Ag‐modified fibers and GO‐modified fibers were obtained by in situ growth of Ag nanoparticles and self‐assembly of GO sheets on cellulose fibers, respectively. Ag‐modified fibers act as a flexible current collector with rich three‐dimensional interconnected electron transport pathways to make the reduced GO‐modified fibers as electrode materials to achieve high conductivity (1.93 Ω sq−1) and high‐rate capability. Simple drying can reduce 40% weight of the supercapacitor to facilitate transportation and storage, and its capacitance efficiency can be recovered by wetting when needed. This work opens up a new way of developing cheap, green and high performance full‐paper flexible electronics by conventional papermaking process.

In this work, a novel polymeric fluorescent brightener agent based on 4,4 0-diamino-stilbene-2,2 0disulfonic acid-triazine structure has been synthesized by radical polymerization. The structure of 4,4 0-diamino-stilbene-2,2 0-disulfonic acid-based polymeric fluorescent brightener agent was characterized by Fourier-transforminfrared spectroscopy, 1 HNMR, and gel permeation chromatography. Photo-property was measured and analyzed by the ultraviolet-vis spectra and fluorescence spectra. The performance on paper was evaluated by determining the surface strength and smoothness, the brightness degree, and the post color number value of paper. Results showed that 4,4 0-diamino-stilbene-2,2 0-disulfonic acid-based polymeric fluorescent brightener agent had a better light stability in water solution than that of 4,4 0-diamino-stilbene-2,2 0disulfonic acid-based fluorescent monomer as light stabilizer. Through the surface-sizing experiment and ultraviolet aging experiment, the 4,4 0-diamino-stilbene-2,2 0-disulfonic acid-based polymeric fluorescent brightener agent not only enhanced the surface strength and smoothness of paper as a surface-sizing agent, but also had a better effect on anti-ultraviolet aging than that of 4,4 0-diaminostilbene-2,2 0-disulfonic acid-based fluorescent monomer as a light stabilizer and fluorescent brightener agent.
