Study on the Preparation and Performance of Natural Polygonum Cuspidatum Sieb.et Zucc Pigments Dyed PBS Composite
The Polygonum Cuspidatum Sieb.et Zucc natural pigments were extracted and compounded with PBS in this paper.The performances of the pigment and the dyed films were studied.The results showed that:both the natural pigment and the dyed films had good thermal stability.Under the acidic conditions,the absorbance of the pigment changed little.The effect to the dyed films by pH indicated the pigments dissolved out of PBS with the degradation.The antibacterial evaluation demonstrated that the natural pigments had good inhibition against Staphylococcus aureus and Escherichia coil The antibacterial properties of the films were not obvious,but it also revealed that the pigment and PBS had the good compatibility.
