聚合物PS和PMMA良溶劑和不良溶劑問題
|
||||
|
乳液聚合合成的一個聚苯乙烯PS核聚甲基丙烯酸甲酯PMMA殼的乳膠球,想找兩種溶劑,一種是只溶解(或溶脹)PMMA,對PS沒有一點影響,另一種是只溶解(或溶脹)PS,對PMMA沒有一點影響. 謝謝大家熱心幫忙,或者告知怎么去查相關(guān)資料 |

在Thurn-Albrecht, T., et al., Adv. Mater. (2000) 12, 787.(Nanoscopic templates from oriented block copolymer films)文章的789頁:It is clear from the results shown that, by a selective removal of the PMMA, an ordered nanoporous material can be produced if the surrounding PS matrix remains intact. FESEM images of the surface of a film that was exposed to 25 J/cm2 deep UV radiation, placed in acetic acid, (a selective solvent for PMMA) for 2 h and then rinsed in deionized water, show an ordered array of circular holes, in keeping with the electron microscopy and small-angle neutron scattering (SANS) results. 所以acetic acid(乙酸)就可以溶解(或溶脹)PMMA,對PS沒有一點影響。 |

在Albert, J. N. L. and T. H. Epps (2010). "Self-assembly of block copolymer thin films." Materials Today 13(6): 24-33.中的30頁:In one example, Xuan et al.70 compared ultrathin (< ½ × L0 thickness) lamellar PS-b-PMMA films annealed with acetone (strongly PMMA selective), chloroform (slightly PMMA selective), toluene (slightly PS selective), and carbon disulfide (highly PS selective). 我想這段話,更能解決你的問題吧。在這方面的研究,應(yīng)化所的韓艷春研究員的研究很出色,呵呵 |
