Embodiment 1

[0038] 10% by weight of polyvinyl alcohol (PVA, 87-89% hydrolyzed, Sigma-Aldrich) was dissolved in distilled water under a temperature condition of 60°C to prepare a PVA solution. To the obtained PVA solution, sulfosuccinic acid (SSA, Aldrich) as a crosslinking agent was added at 20% by weight relative to the weight of the PVA, and stirred for 1 hour or more. In addition, 1% by weight of zeolite A based on the weight of PVA was added to prepare a polymer composite material solution.

[0039] The prepared polymer composite solution was electrospun with an electrospinning device (NT-PS-35K, NTSEE Co., Korea) to fabricate a polymer nanofiber sheet. The voltage used for electrospinning was 20 kV, while the distance between the positively charged needle and the negatively charged cluster was 18 cm. The syringe for injecting the spinning solution used a 10 ml syringe made of glass, and the diameter of the needle was 0.5 mm. The supply rate of the solution was 0.7 ml per hour, and ...

Embodiment 2-4

[0043] 10% by weight of polyvinyl alcohol (PVA, 87-89% hydrolyzed, sigma-aldrich) was dissolved in distilled water under a temperature condition of 60°C to prepare a PVA solution. In addition, 10% by weight of a polystyrenesulfonic acid / maleic acid copolymer (PSSA-MA, sigma-aldrich) was produced using distilled water. The obtained 10% by weight PVA solution and 10% by weight PSSA-MA solution were mixed and stirred so that the ratios of PVA:PSSA-MA were 9:1 (Example 2), 8:2 (Example 3) and 7 : 3 (embodiment 4), to make PVA / PSSA-MA solution. To the prepared mixed solution, sulfosuccinic acid (SSA, Aldrich) as a crosslinking agent was added in an amount of 20% by weight based on the weight of PVA, and stirred for more than 1 hour to perform a crosslinking reaction.

Embodiment 5-7

[0048] 10% by weight of polyvinyl alcohol (PVA, 87-89% hydrolyzed, sigma-aldrich) was dissolved in distilled water under a temperature condition of 60°C to prepare a PVA solution. In addition, 10% by weight of a polystyrenesulfonic acid / maleic acid copolymer (PSSA-MA, sigma-aldrich) was produced using distilled water. The prepared 10% by weight PVA solution and 10% by weight PSSA-MA solution were mixed and stirred so that the ratio of PVA:PSSA-MA became 9:1 to prepare a PVA / PSSA-MA solution. In the prepared mixed solution, add sulfosuccinic acid (SSA, Aldrich) as a cross-linking agent in an amount of 20% by weight based on the weight of PVA and stir for more than 1 hour to carry out a cross-linking reaction, thereby obtaining a polymer solution (Example 6). Here, 1% of zeolite A was added based on the polymer weight to prepare a polymer composite material solution (Example 7).

Abstract

The present disclosure relates to the preparation of a polymer composite material for building air conditioning or dehumidification having superior water-adsorbing ability, durability and antibacterial properties by electrospinning. Specifically, the disclosed method for preparing a polymer composite material for building air conditioning or dehumidification includes: (Sl) adding a crosslinking agent or a crosslinking agent and a porous filler into a hydrophilic polymer solution or a polymer mixed solution for conferring durability and antibacterial properties, so as to prepare a polymer composite material solution; (S2) electrospinning the polymer composite material solution to prepare a nanofiber sheet; and (S3) crosslinking the nanofiber sheet by heat-treatment. Since the disclosed polymer composite material for building air conditioning or dehumidification has superior antibacterial properties and excellent water-adsorbing ability and durability, the polymer composite material can adsorb latent heat load contained in moisture of the indoor air when used for air conditioning of a building, thereby reducing air conditioning load, saving energy, and supplying fresh air for the indoor environment. Further, through dehumidifying cooling, the high-efficiency polymer composite material can remove moisture from the hot and humid air in the summer, and can separate sensible heat load from latent heat load, thereby reducing air conditioning load by decreasing latent heat load and saving energy. In addition, the polymer composite material can be used in moisture-sensitive production processes, industrial applications requiring moisture control or protection from damage or corrosion by moisture to reduce moisture in the air and obtain dry air.
