Effect of Draw Ratio on the Surface Energy of Polycapramide Film

연신비가 폴리카프라미드 막의 표면 에너지에 미치는 영향

Critical surface tension γc, dispersion γsd, polar γsp including hydrogen bonding, polar γspr excluding hydrogen bonding, and hydrogen bonding γsh contributions of the solid surface tension γs for polycapramide film prepared under various draw ratios were determined by Zisman's plot, Kaelble's computational analysis and extended Fowkes' equation, respectively. It is indicated that the increase in γs of the film surface with draw ratio is mainly due to hydrogen bonding contribution.
