在Introducition部分，稿件与一篇发表的文章有如下雷同，算抄袭么？ 第一处： 稿件：Exploring crystal structures of semicrystalline polymers is of both scientific and technological interest and importance because of their dramatic impact on most of their performances.1,2 Spherulites, as the most common morphology of polymer crystal, can be obtained when many polymers crystallized from cooling melt or concentrating solution. Specially, ring-banded spherulites, as interesting and representative morphological feature of polymer crystalline aggregates, have been attracting considerable attention for several decades.3-7 发表的文章：Exploring crystal morphologies of semicrystalline polymers is of both scientific and technological interest and importance because of their dramatic impact on material performance.1−4 Spherulites, as the most common morphology, can be encountered when polymers crystallized from disordered melt or concentrated solution. Specially, ring-banded spherulites have received extensive attention due to their attractive feature. 第二处： 稿件：Generally, in ultrathin films of crystallized polymer, in addition to extinction banding, concentric rings that possess sharp contrast in both polarized and unpolarized light,24,25 or even appear directly opposite optical features with extinction banding, i.e., poor contrast under polarized light and clear appearance in unpolarized light,26-29 were also observed in two-dimensional polymer spherulites. Actually, these concentric rings are a reflection of periodic change of thickness caused by the rhythmic-crystallization-induced structural discontinuity. Ring-banded spherulites with this kind of discrete structure also occurred in some polymer blends.30-32 发表的文章：Yet, in thin films, in addition to extinction banding, concentric rings that possess sharp contrast in both polarized and unpolarized light,10,11 or even appear directly opposite optical features with extinction banding, i.e., poor contrast under polarized light and clear appearance in unpolarized light,12−15 were also observed in two-dimensional polymer spherulites. Actually, these concentric rings are a reflection of periodic change of thickness stemming from rhythmic-crystallization-induced structural discontinuity. Ringbanded spherulites with the discrete structure also occurred in some polymer blends.16−18 第三处： 稿件：Consequently, the effects of structural feature and crystallization condition on polymer lamellar packing and orientation and then formation of different ring-banded spherulites are quite unclear. In the present work, we further explored the spherulite morphologies of poly(trimethylene terephthalate) from a standpoint of controlling lamellar packing by tuning the crystallization condition aiming to reveal the possible factors that influence lamellar actions and the appearance of ring-banded shperulites. To our knowledge, it is the first time that two kinds of ring-banded spherulites were encountered in the same homopolymer. Morphological transitions among different spherulites and the crystallization of PTT were analyzed. Finally, we discussed the effects of crystallization condition on radial lamellar organization of polymer spherulites. 发表的文章:Concomitantly, the effects of structural feature and crystallization condition on radial lamellar packing and orientation and then formation of different ring-banded spherulites are quite unclear. In the present work, we further explored the spherulite morphologies of a highly asymmetrical poly(ε-caprolactone-bethylene oxide) diblock copolymer from a standpoint of tuning lamellar organization by controlling evaporation of solutioncast films in an attempt to unveil possible factors that govern radial lamellar packing and orientation and then appearance of different ring-banded patterns in polymer thin films. To our knowledge, it is the first time that three kinds of ring-banded spherulites were encountered in the same polymer. Morphological transitions among various spherulites and the crystallization of PEO block were also analyzed. Finally, we discussed the effects of structural feature and crystallization condition on radial lamellar organization of polymer spherulites. |
