Aggregation States of Polyamide 4 Thin Films under an Aqueous Environment |
| 초록 |
Polyamide 4 (PA4) having only four carbons between neighboring amide groups exhibits enhanced biodegradability, and thus, has been studied as one of candidates for eco-friendly structural materials. However, the biodegradation mechanism for PA4 is far clear for a moment. We here examined the aggregation states of PA4 thin films coated on a hydrophobized SiOx substrate using atomic force microscopy (AFM) and neutron reflectivity (NR) analyses in air and water environments. AFM observation revealed that the outermost surface of the PA4 film was featureless and flat at a nanometer level. Once the film was immersed into water, the thickness increased by approximately 1.1 times. NR made it clear that the PA4 film was swollen due to the water sorption in the film, and that there existed multiple layers having different densities along the direction normal to the interface. Effect of annealing temperature on such the aggregation states and the degradability will be also discussed. |
