The present invention discloses a method for preparing titanium dioxide-based synthetic paper, comprising steps of using titanium dioxide and polyurethane as main raw materials, stirring and mixing titanium dioxide powder and the prepared polyurethane solution, subsequently curing to form a film to obtain the titanium dioxide-based synthetic paper. The synthetic paper product of the present invention is of a porous structure which facilitates the adsorption of organic pollutants in the indoor air. During the production, lots of pores are formed both on the surface of the synthetic paper and inside the synthetic paper, by which the adsorption of the organic pollutants in the indoor air by the synthetic paper is improved greatly. It can effectively degrade organic pollutants under mild conditions. Inorganic filler can degrade the organic pollutants adsorbed onto the surface of the synthetic paper and inside the synthetic paper, with only nontoxic substance generated.

The invention is to provide a base paper for a raising seedling pot and a raising seedling pot produced from the base paper, wherein while the base paper maintains a sufficient strength during raising seedlings and planting in the field, it is degraded over time by soil microorganisms after transplanting in the field and is produced by using a crosslinking agent that does not contain formaldehyde, resulting in a reduced burden on the environment; the base paper for a raising seedling pot, wherein a citric acid crosslinking agent, as a crosslinking agent for cellulose, is used in order to block the hydroxy group of cellulose in paper through crosslinking; and the raising seedling pot produced by molding and processing the base paper.

A hydrated, nonwoven nanocellulose sheet and method for manufacturing the nanocellulose sheet are disclosed. The method of manufacture comprises the steps of diluting a purified nanocellulose slurry to form a colloidal nanocellulose suspension, dispersing pure nanocellulose crystals into the nanocellulose suspension in a nanocellulose crystal to total nanocellulose ratio less than 50% weight per weight (w/w), placing the suspension over a filter sheet in a dispensing device, and forming the hydrated, nonwoven nanocellulose sheet by filtering with a pressure difference across the filter sheet, via a high pressure or vacuum filtration process. The hydrated, nonwoven nanocellulose sheet thus manufactured has high conformability, drape-ability, good adhesion to the skin, and a high rate of evaporation, making it ideal for dermatological treatments.

Electrical insulating paper according to an embodiment of the present invention is used while being immersed in electrical insulating oil, and includes a paper base material mainly containing cellulose, an adsorption layer formed on an entire surface of the paper base material by adsorption, and a moisture barrier layer formed by being chemically bonded to the adsorption layer. The moisture barrier layer includes an amphipathic molecule containing both a hydrophobic hydrocarbon group and a hydrophilic functional group in one molecule. The amphipathic molecule is chemically bonded to the adsorption layer via the hydrophilic functional group. The hydrophobic hydrocarbon group covers the surface of the paper base material.
