Abstract: The present invention relates to a manufacturing method of a carboxymethyl cellulose nonwoven fabric which includes the carboxymethylation of cellulose fibers and the subsequent paper-making process to prepare a carboxymethyl cellulose nonwoven fabric. Comparing with the conventional method involving carboxymethylation of a nonwoven fabric, the method of the present invention has convenience and easiness of the process and thus enables production on a large scale. Further, the carboxymethyl cellulose nonwoven fabric manufactured by the present invention is susceptible to gelation upon contact with body fluids or water and thus useful as a medical nonwoven fabric or a mask pack.

Abstract: The present invention provides a method for preparing a compound with a benzimidazole structure with an excellent yield using a low-cost starting material, not requiring an additional separation process, or not using a dangerous reagent during the manufacturing process. Furthermore, the present invention also provides an intermediate and a final product produced by the preparing method.

Abstract: Disclosed herein is a method for preparation of a meso-porous polymer nano-composite material which includes: drying a solid material having pores under vacuum; adding a first organic solvent to the vacuum dried solid material in the reactor and dispersing the first organic solvent in pores of the solid material; adding a constant amount of a material having radicals or functional groups relative to weight of the mixture containing the solid material and the first organic solvent in a reactor, and agitating the mixture; introducing a polymerization initiator into the reactor; using a second organic solvent to filter and wash the reaction product after completion of the polymerization; and drying the treated product to eliminate the second organic solvent from the same after removal of the unreacted material having radicals or functional groups as well as the polymerization initiator from the product.

Abstract: Disclosed herein is a method for preparation of a mesoporous polymer nano-composite material, more particularly, a method for preparation of a meso-porous polymer nano-polymerized composite material which includes: drying a solid material having pores under vacuum at ambient temperature and pressure; adding a first organic solvent to the vacuum dried solid material in the reactor and dispersing the first organic solvent in pores of the solid material by an ultrasonicator to remove air while wetting a surface of the solid material with acetonitrile; adding a constant amount of a material having radicals or functional groups relative to weight of the mixture containing the solid material and the first organic solvent in a reactor, which was prepared in the above step, and agitating the mixture; introducing a polymerization initiator into the reactor containing the mixture prepared in the above step, in order to initiate polymerization of the mixture in the reactor; using a second organic solvent to filter and w
