The results of attenuated total reflectance - fourier transform infrared ( atr - ftir ) , x - ray photoelectron spectroscopy ( xps ) and contact angle measurement showed that the amphiphilic copolymer could self - segregate on the hydrophobic pdl - la surface 利用衰减全反射傅立叶转换红外光谱( atr - ftir ) 、 x -射线光电子能谱( xps )分析以及接触角测定对改性聚乳酸材料表面进行了表征。
百科解释
Attenuated total reflectance (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation.
