However, the shell solution viscosity should be high enough to maintain the coaxial structure of the solution jet from the injection nozzle until full solidification.33 At a too-low viscosity ratio of PAN/PMMA of 0.67, we could observe Figure 2 FTIR spectra of PAN and PAN/PMMA fibers. ...

(DDS)固化时相分离结构的控制在反应初期为均相体系随固化反应的进行,环氧的分子量增大,体系发生相分离相差显微镜观察结果表明,温度较低时相分离进行缓慢,遵循族节相分离的机理利用这一特点,在低温进行共混物预固化,调控反应程度,在环氧树脂达到不同的分子量时再行固化电子显微镜(SEM),红外(FTIR)分析的结果表明通过...
1. Introduction Poly(methyl methacrylate) (PMMA) is a very versatile polymer due to its excellent properties such as resistance to strong alkaline or acid solutions and its stability to heat and light. The polymer behaves quite satisfactory in the presence of very aggressive environments. Therefore...
