Abstract:
A method to prepare polymer woven fabric surface with selective oleophilicity or hydrophobicity and oil-oil separation and oil-water separation filter prepared by using the surface. The method to prepare the surface with selective oleophilicity or hydrophobicity includes steps comprising a step to form nano meter sized pores on the surface of the polymer woven fabric surface with micro sized pores through drying type etching; and a step to form selective oleophobic or hydrophobic film on the nano meter sized pores. It is possible to control hydrophobic/oleophobic property according to pore size, material or thickness of the film and this polymer surface with hybrid pores can be used in various areas such as an oil filter for car capable of selective separation of oil-oil mixture and water-oil mixture, disposal of waste oil, treatment of marine oil leakage, and pretreatment of crude oil refinement.
Abstract:
Disclosed are a polylactide stereocomplex with improved thermal stability and thus improved processability and a method for preparing the same. In order to confer flexibility to polymer chains, D-type polylactide polymer containing a small amount of caprolactone (poly D-lactide-caprolactone copolymer) is synthesized and it is uniformly mixed with L-type single-phase polylactide to prepare a flexible polylactide stereocomplex. Since the polylactide stereocomplex having flexible polymer chains has superior heat resistance and mechanical stability and experiences little decrease of the degree of stereocomplex formation even after thermal processing, the polylactide stereocomplex having improved thermal stability can be advantageously used for engineering plastics requiring high strength and good thermal stability, alternative materials for general-use plastics, high-performance medical materials, or the like because of its remarkably improved processability.
