Properties of Surface Modified 45S5/PDLLA Composite Films Treated with Boiling Water
沸水处理对45S5生物活性玻璃/聚乳酸复合膜性能的影响

45S5 bioactive glasses(BGs) were surface-modified with dodecyl alcohol through esterification reaction to get 45S5/PDLLA composite films.The properties of the composite films before and after treatment in boiling water for 20min were investigated.The results show that water contact angles of the composite films decrease sharply after the boling water treatment,indicating the improvement of the hydrophilicity of the composite films.Furthermore,after boiling water treatment,the tensile strength of the composi...
