The present invention relates to an organic polymer adsorbent, an organic polymer adsorbent composition, and a method for preparing an organic polymer adsorbent and, more specifically, to an organic polymer adsorbent to be used for a ventilation device such as a desiccant dehumidifier. According to the present invention, an adsorbent material is changed to an organic polymer adsorbent such that the mechanical stability and durability of the material itself can be ensured, and the specific surface area of interconnected inner pores and adsorbents and the size of formed pores can be controlled since toluene is contained as a pore generator of the adsorbent. Therefore, the adsorbent of the present invention has superior adsorption performance over that of other conventional organic polymer adsorbents containing a salt-type carboxyl group and has remarkably improved desorption performance, and thus has an effect of very remarkable energy efficiency.

Freestanding porous polyethylene thin film, and a method for preparing a freestanding porous polyethylene thin film. The method includes dissolving polyethylene in an organic solvent to form a solution under reflux conditions; adding a swellable pocket forming agent to the solution and mixing the solution until the swellable pocket forming agent is well-dispersed therein; applying the well-dispersed solution onto a solid substrate through spin coating to form a thin film on the solid substrate; peeling the thin film off the solid substrate; and extracting the swellable pocket forming agent from the peeled thin film by washing the peeled thin film in water, thereby obtaining a freestanding porous polyethylene thin film with swellable pockets, macro-voids, and micropores. The freestanding porous polyethylene thin film can be used as an oil sorbent. The freestanding porous polyethylene thin film has about 500 to about 800 swellable cavities per cm.sup.2.

Polypropylene (PP) and polyethylene (PE) blends derived from plastic waste streams and a method to prepare reusable oil sorbents. A method includes separating plastics of group-A from group-B using a float-sink technique, where group-A comprises various PP and PE materials, and group-B comprises polystyrene, polyethylene terephthalate, and polyvinyl chloride; dissolving the group-A plastics in a solvent; adding a cavity forming agent to the solution; applying the solution onto a solid substrate through spin-coating followed by controlled heating; and extracting the cavity forming agent, obtaining a thin film sorbent with swellable cavities for oil sorption. The film contains 400-800 swellable 3D cavities/cm.sup.2, each cavity capable of swelling 20-30 times the thickness of the film when contacted with oil. The method improves compatibility of PP-PE blends without using compatibilizers, resulting in high oil uptake capacity due to swellable cavities, and reusability of sorbent with an oil recovery of more than 98%.
