Highly crystalline polyaniline (PANI) nanostructures were synthesized via oxidative polymerization using ammonium persulfate (APS) as an oxidant and sucrose octaacetate as in situ seeds and a soft template. Using 2 and 3 grams of sucrose octaacetate resulted in the formation of PANI nanofibers and nanorods, respectively.
Synthesis of Polyaniline
Under acidic conditions, PANI nanofibers were synthesized by the oxidative polymerization of aniline using APS as the oxidant and sucrose octaacetate as in situ seeds and a soft template. The synthesis procedure is as follows: a specific amount of sucrose octaacetate (0.5, 1, 2, 3, 4, and 5 grams) was dissolved in 54 ml of ethanol to prepare six different concentrations of sucrose octaacetate solutions. Subsequently, 2 grams (0.021 mol) of aniline monomer was added to each sucrose octaacetate solution. The mixtures were cooled to 0 °C while being mechanically stirred and maintained at this temperature for 30 minutes. Then, 36 ml of 2.8 M HCl was added to each mixture, followed by an additional 30 minutes of mechanical stirring. A 25 ml distilled water solution containing 4.9 grams (0.021 mol) of APS was then added dropwise over 1 hour. The reaction mixtures were stirred at 0 °C for 5 hours to complete the polymerization process. The resulting precipitates were filtered and sequentially washed with ethanol, acetone, and distilled water to thoroughly remove any residual sucrose octaacetate. Finally, the obtained PANI products were dried in an oven at 60 °C for 24 hours.

Surface coating of paper is a common method in the paper industry to enhance paper quality. Surface sizing can improve mechanical strength, smoothness, water resistance, and reduce surface porosity. In this study, the surface sizing of paper using sucrose octaacetate (SOA) is reported. Studies indicate that SOA surface coating is smooth and uniform. Contact angle measurements and adsorption studies reveal that the SOA-coated paper surface is hydrophobic. It is observed that the mechanical properties of SOA-coated paper are superior to those of uncoated paper.
Preparation of SOA-Coated Paper
Initially, sucrose octaacetate (SOA) is loaded into a cell, and the paper to be sized (5 cm × 1 cm) is suspended at the top of the cell. The temperature of the cell is maintained at 25 °C using a water circulation system connected to a temperature controller. Compressed CO2 is introduced into the cell using a JASCO pump, and the CO2 pressure is increased to 65 bar. SOA melts into the CO2 and then dissolves completely, with the paper immersed in the SOA-CO2 solution. Finally, the observation chamber is depressurized at a constant rate of 1 bar/min using a back pressure regulator. The sized paper obtained is then collected and characterized.
