spherulites
解釋
球粒-
Pcl could form banded spherulites through blending with poly ( bisphenol a - co - decane ) lamellar structures of banded spherulites of poly ( s - caprolactone ) / poly ( vinyl chloride ) ( pcl / pvc ) blends were observed using tapping mode atomic force microscopy ( afm )
利用原子力顯微鏡( afm )的輕敲( tapping )模式,系統地研究了聚-己內酯聚氯乙烯共混體系形成的環帶球晶表面形貌和片晶結構。 -
The lamellae with edge - on and the flat - on orientation alternated to form the banded spherulites
利用原子力顯微鏡原位觀察了環帶球晶界面的片晶生長。 -
The thickness had some influence on the development of the banded spherulites : when the thickness reduced to some degree, pcl would develop chrysanthemum - like spherulites, which had no extinction rings or the maltese cross pattern under the crossed polarized optical microscopy. the results of the phase - contrast microscopy showed that growth speed of the chrysanthemum - like spherulites along the radius was not constant
發現薄膜厚度對球晶的生長有一定的影響,當共混物膜薄到一定程度時, pcl不能形成環帶球晶,而是形成一種類似菊花狀的晶體,在偏光顯微鏡下看不到環帶,也沒有典型球晶所特有的maltese十字消光圖案。 -
Spherulites dimension also decreases due to the chemical changes occurred during pan - milling. viscosity test shows that chain scission occurred during pan - milling, which caused slight reduction of mechanical properties. polypropylene / polyamide 6 ( pp / pa6 ) ultra - fine powder was prepared through pan - milling at ambient temperature
通過磨盤碾磨在常溫下制備了聚丙烯/尼龍6 ( pp / pa6 )超細復合粉體,其粒徑可通過碾磨時間、磨盤轉速、磨面靜壓力、碾磨溫度等工藝參數控s摘要一制。 -
The growth of lamellae at the interface of the banded spherulites was studied in situ using atomic force microscopy ( afm ) with a hot - stage
研究表明,片晶的扭轉不是一個漸變的過程,而是發生在相對較窄的區域。 -
The lamellae in different directions could join and stop growing by each other at the interface of spherulites, which lead the formation of defects
在球晶的edge - on片晶生長前沿相遇時,形成片晶束。也有的片晶在互相接觸后停止生長,導致缺陷增多。 -
The growth speed was forced to decreased by the spatial hindrance and limitation of the crystalline chain segment during the closing up of the two spherulites
在結晶的早期,片晶在生長過程中, edge - on片晶和flat - on片晶交替取向,逐漸充滿球形的空間。 -
The lamellae with edge - on orientation in the ridges and the flat - on lamellae in the valleys of the banded spherulites were observed clearly. the twisting between the edge - on and flat - on lamellae was also observed
片晶在凹下環帶區域的排列主要是flat - on取向,而凸起環帶區域的片晶排列主要是edge - on取向。 -
Polarized optical microscopy and phase - contrast microscopy were used to observe the banded spherulites of poly ( e - caprolactone ) / poly ( vinyl chloride ) ( pcl / pvc ) blends. the ring spacing and regularity of the banded spherulites decreased with the decrease of the crystallizing temperature
本文利用偏光顯微鏡和相差顯微鏡觀察了聚-己內酯聚氯乙烯形成的環帶球晶,環帶間距隨溫度的降低而減小,規整性亦隨之下降。 -
Study on the spherulites of polypropylene
聚丙烯球晶的研究 -
The surface of the pcl / pvc banded spherulites presented to be concentric periodic ups and downs. the period of the bands corresponded to the extinction rings under the polarized optical microscopy observation
Pcl環帶球晶的表面由周期性高低起伏的環狀結構組成,其凸凹起伏的環帶與球晶在偏光顯微鏡下的明暗交替相對應。
