dc.description.abstract | 本研究中利用原子轉移自由基聚合法製
備不同分子量及鏈段長度之PS-b-PMSMA 嵌
段共聚物。GPC 結果顯示在適當的操作條件
下製備所得之PS-b-PMSMA 其分子量在
30,000 以下,其分子量分布可控制在1.3 以
下。另外,此雙親性之PS-b-PMSMA 嵌段共
聚物的化學結構亦由FTIR 及NMR 的分析結
果證實。SEM 圖可看出PS-b-PMSMA 嵌段共
聚物在油相溶劑中之微胞大小隨PS 及
PMSMA 鏈鍛大小而不同。XPS 、DES 及SCMS
分析亦證實CdS 粒子已成功被製備在
PS-b-PMSMA 的複合膜中。由TEM 及SEM
圖分析得知所製備複合膜結構為數百nm 之
compound micelle 中包含許多大小在4~6 nm
的小微胞(single micelle)。UV-Vis 及PL 的分
析結果則顯示本實驗中所得到的懸浮CdS 粒
子其最大吸收及發射波長隨CdS 粒徑大小增
加而有紅移的現象產生,且CdS 的顆粒大小
約為4-5 nm 。由本研究可知由雙親性嵌段共
聚物PS-b- PMSMA 可控制CdS 之成長粒徑並
形成compound micelle 中有single micelle 之
結構,並具發光特性,這將於多層結構之光
電複合薄膜將極具應用潛力。 | zh_TW |
dc.description.abstract | In this study, block copolymers of
PS-b-PMSMA with various molecular weight
and block length were synthesized by atom
transfer radical polymerization (ATRP). The
GPC analysis showed that the molecular weight
distribution of the prepared PS-b-PMSMA could
be controlled to be lower than 1.3 for the
molecular weight less than 30,000. The
chemical structures of the amphiphilic block
copolymers of PS-b-PMSMA were well
identified by FTIR and NMR. The TEM and
SEM images showed that the lengths of PS and
PMSMA segments could control the size of
micelles in solution or film. The morphology of
the composite films exhibited as several
hundred nm compound micelles contained a few
4-6 nm single micelles. The results of XPS 、
DES and SCMS analysis indicated that the
nano-size CdS particles have been successfully
prepared in the PS-b-PMSMA composite films.
The UV-Vis and PL analysis also revealed that
the λ max of prepared CdS particles were red-shift
as the CdS particle size increased. Besides, the
diameter of CdS particles estimated from Brus
formula was about 4-5 nm. Our study
demonstrated the successful preparation of
CdS/polymer composite films with controllable
structure within structure morphology, which
would be potential used for multifunctional
optoelectronic composite films. | en |
