Formaldehyde is a major ingredient of heat insulating materials and adhesives, and it has been known as a cause of sick house syndrome. The exposure to formaldehyde for a long time leads to fatal diseases. In this study, the electrospinning method was applied to prepare the blended nanofiber of polyethyleneimine(PEI) and polyvinylalcohol(PVA), and formaldehyde adsorption experiments were carried out. The PVA/PEI blended nanofiber was analyzed by scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). SEM observations showed PVA/PEI blended nanofiber having a diameter of about 113.5 nm. And XPS showed the deconvoluted peak of C=N-C at 399 eV for N1s. The peak area of C=N-C was quantified by performing a deconvoluted peak analysis and it was increased from 8.3% to 55.9%.
