Abstract

The blend films of poly(3-hydroxybutyric acid) (PHB) with chitosan were prepared and water vapor transmission rate, oxygen permeability and lipid permeability of the PHB/chitosan films were measured. Additionally, the biodegradability of the PHB/chitosan films was also evaluated. Water vapor transmission rate and oxygen permeability of the films decreased by the addition of chitosan. The addition of polyethylene glycol (PEG, plasticizer), however, increased the water vapor transmission rate and oxygen permeability of the films. In the evaluation of lipid permeability, all the films except PHB (the film made of only PHB) and PHB-P (the film made of PHB and PEG) did not permeate beef tallow for 24 hours. The consumed oxygen for PHB/chitosan films during incubation was greater than that for the control on the biodegradability determination of the films, which implies that PHB/chitosan films were degraded by the microorganisms. The higher PHB ratio of the films was, the faster biodegradation of the films occurred.

PHB/chitosan 필름의 수분 투과도는 PHB 필름께서 280.25 g/m$^2$ㆍ24 hr로 가장 높았고 chitosan의 함량이 증파할수록 수분 투과도는 낮아지는 경향을 보였다. PEG가 첨가된 PHB/chitosan 필름에서도 PHB-P 필름의 수분 투과도가 294.5 g/m$^2$ㆍ24 hr로 가장 높았고, chitosan의 함량이 증가할수록 수분 투과도는 낮아졌다. 산소 투과도의 경우 PHB 필름이 0.026${\times}$$10^{-10}$$cm^3$(STP) cm/$cm^2$ㆍsecㆍcmHg로 가장 높았으며 chitosan의 첨가 비율이 증가할수록 산소 투과도는 낮아졌다. 또한 가소제인 PEG가 첨가되지 않은 필름이 PEG가 첨가된 필름보다 산소 투과도가 더 낮았다. 유지 투과도에서는 PHB와 PHB-P를 제외한 필름들이 24시간동안 유지론 통과시키지 않아 유지 차단성이 우수한 것으로 나타났다. 필름의 생분해도 측정시 필름을 첨가하지 않은 대조군에 비해 필름이 첨가된 실험군의 산소 소모량이 높아 필름이 생분해되고 있음을 확인할 수 있었으며 필름의 PHB의 비율이 높을수록 분해도가 높은 것으로 나타났다.
