气泡在膨胀的过程中可以对周围高聚物做功,并利用相互作用力能够对纳米材料进行有效分散,实验分别通过对膨胀石墨和自制棒状纳米级甲基丙烯酸甲酯与苯乙烯共聚物(MMA-At)与聚甲基丙烯酸甲酯(PMMA)共混过程中使用和不使用原位气泡拉伸法(IABA)进行研究,通过扫描电镜(AEM),X射线衍射(XRD)分析证明使用IABS方法后石墨的长度为未使用的1/7.5,自制的棒状纳米高聚物团聚颗粒在基体中几乎没有了,全部均匀分散到基体中,实验也对加工制得的标准样条进行力学性能测试,数据表明:使用ISBS方法分散添加膨胀石墨可以提高材料的冲击强度达到214%,而使用此方法分散添加自制的棒状纳米PMMA-At可以提高材料的拉伸强度达到72.9%。
Bubbles in the process of expansion can work on the surrounding polymer, and the use of the interaction force can effectively disperse the nano-materials, experiments were conducted on expanded graphite and self-made rod-shaped nano-methyl methacrylate and styrene copolymer (MMA -At) and polymethylmethacrylate (PMMA) with and without the use of in situ bubble stretching (IABA) were studied by scanning electron microscopy (AEM), X-ray diffraction (XRD) analysis showed that the use of IABS After the method, the length of the graphite is unused 1 / 7.5. The self-made rod-shaped nano-polymer agglomeration particles are almost not dispersed in the matrix and are uniformly dispersed in the matrix. The mechanical properties of the prepared standard spline are also tested The data shows that the ISBS method can increase the impact strength of the material by 214%. However, using this method to disperse the self-made rod-shaped nano-PMMA-At can increase the tensile strength of the material to 72.9%.
