[求助] 几句论文求大神翻译成中文谢谢

Surface Wettability of Unmodified and Modified
PHBV Films. The surface wettability of different PHBV films
was investigated through a water contact angle method. The
contact angle of the PHBV film was found to be 72 ( 1. After
NH3 plasma treatment, the contact angle decreased to 36 ( 4
because of the increasing polarity and roughness of the surface
caused by the introduction of hydrophilic groups.21,22 However,
it was reported that within the first 3 h after treatment, the
contact angle increased significantly. After 1 day of storage in air,
the contact angle of theNH3 plasma-treated PHBV films reached
a value similar to that of an unmodified surface. The effect of
wettability reversal is likely due to chain relaxation processes and
postreaction with the storage environment.

未修饰和修饰的PHBV膜的表面润湿性。通过水接触角法研究了各种PHBV膜的表面润湿性。经发现PHBV膜的接触角为72 ( 1。经NH3血浆治疗后,接触角减少到36 ( 4这是因为由引入亲水基团所引起是表面极性和粗糙度增大。 21,22然而,据报道治疗后3小时之内接触角显著地增大。空气中存放1天之后, NH3等离子体处理过的PHBV膜的接触角达到与未修饰表面相似的值。润湿性逆转的影响很可能是由于链松弛过程和对贮存环境的补充反应。
