“…Agricultural residues are used in many types of applications such as biomass energy, fertilizers, livestock feeding, and furniture. In Egypt, agriculture residues like rice straw, bagasse, and cotton stalks are produced in mass amounts [20] and they are currently used in the paper industry [21]. In this industry, paper with improved intrinsic properties obtained from agricultural waste is significantly very important in terms of control of secondary pollution and sustainability.…”

Different amounts of a stable aqueous TiO2 hydrosol were used to fabricate paper sheets having photocatalytic activity. The TiO2 hydrosol was prepared in aqueous medium using titanium butoxide as precursor and acetic acid as catalyst for the hydrolysis of titanium butoxide. An aging process at room temperature and atmospheric pressure was finally applied to obtain crystalline anatase TiO2 hydrosol. The effects of different TiO2 hydrosol loadings on the mechanical strength and barrier properties of modified paper sheets were investigated in detail. The photocatalytic behavior of TiO2-modified paper sheets was investigated as well using methylene blue (MB) as target pollutant.

“…Nanocellulose is a new class of nanomaterials, which has unique properties, such as nanoscalability and biocompati-bility and being a renewable and biodegradable material, that enable its use in many fields [4,5]. Nanocellulose is used in optoelectronics, in the production of chemical current of sources and sorbents, for reinforcing and improving the thermal stability of polymeric and paper composites [6][7][8]. Nanocellulose has been incorporated into polymer matrices to produce reinforced composites of tenfold to hundredfold mechanical strength [9], as well as enhanced optical transparency [10].…”

Miscanthus x giganteus stalks were used to make organosolvent pulp and nanocellulose. The organosolvent miscanthus pulp (OMP) was obtained through thermal treatment in the mixture of glacial acetic acid and hydrogen peroxide at the first stage and the alkaline treatment at the second stage. Hydrolysis of the never-dried OМP was carried out by a solution of sulfuric acid with concentrations of 43% and 50% and followed by ultrasound treatment. Structural changes and the crystallinity index of OMP and nanocellulose were studied by SEM and FTIR methods. X-ray diffraction analysis confirmed an increase in the crystallinity of OMP and nanocellulose as a result of thermochemical treatment. We show that nanocellulose has a density of up to 1.6 g/cm3, transparency up to 82%, and a crystallinity index of 76.5%. The AFM method showed that the particles of nanocellulose have a diameter in the range from 10 to 20 nm. A thermogravimetric analysis confirmed that nanocellulose films have a denser structure and lower mass loss in the temperature range of 320–440°C compared to OMP. The obtained nanocellulose films have high tensile strength up to 195 MPa. The nanocellulose obtained from OMP exhibits the improved properties for the preparation of new nanocomposite materials.

“…Based on the literature, the most common paper strengthening additives are starch, [1][2][3][4][5][6] polyacrylamides 3 and cellulose nanofibers (CNFs). [7][8][9][10][11][12] Starch is the most common and economical additive that increases paper strength, compared to the other conventional resins. 6 Starch is also a main component in the food industry and this makes a competitive demand and sometimes limited availability or periodic price variability for the use in the paper industry.…”

One of the key properties of paper is its breaking length, which is usually controlled in many paper products. To achieve this, several natural and synthetic polymers are used in paper industries in accordance with paper grades and customer needs. In this study, the combination of cationic starch (CS) and/or polyacrylamide (CPAM) as common additives, and cellulose nanofibers (CNFs), were added to a short-fiber pulp suspension to investigate the reinforcement effects and to compare such properties with those of paper prepared with 20% softwood long-fiber. The breaking length was measured on the prepared handsheets. The results showed that adding 1% CS significantly improves paper breaking length, which was well comparable to the handsheets reinforced with 15% softwood pulp. The results showed that adding less CS (0.5%) along with 3% CNFs significantly increased the paper breaking length, while reducing process difficulties associated with CS. The same result was also achieved adding 3% CNFs along with 0.03% CPAM. Furthermore, a triple system of CNFs, CS, and CPAM additives significantly enhanced the paper breaking length and surpassed the breaking length of paper made with 20% softwood pulp. Using this triple system led to the least changes in handsheet thickness as well. Therefore, this triple system of additives can replace softwood pulp, thereby significantly expanding the spectrum of paper products for the countries with limited softwood pulp sources.
