【摘要】：在本研究中,著重介紹了用作金屬納米粒子穩(wěn)定劑的聚酰胺-胺、聚縮水甘油和聚乙烯亞胺等幾類超支化聚合物的研究進(jìn)展。聚酰胺-胺類超支化聚合物可用于堵水劑和化學(xué)驅(qū)油劑,用于金屬納米粒子反應(yīng)器時既作還原劑,又作分散劑,能穩(wěn)定分散金屬納米粒子,還能提高納米復(fù)合材料的循環(huán)再生性能;聚縮水甘油類含有大量的端羥基,經(jīng)修飾可得到兩親性的納米膠囊,具有良好的生物相容性,可用作優(yōu)質(zhì)的原油破乳劑,金屬納米粒子的粒徑可通過其相對分子質(zhì)量來調(diào)控;聚乙烯亞胺-胺類具有眾多的胺官能團(tuán),為金屬離子的配位提供了豐富的位點(diǎn),其包裹的金屬納米粒子可用于溫敏材料等。結(jié)合超支化聚合物的結(jié)構(gòu)可控性以及納米金屬優(yōu)秀的催化性能,這類物質(zhì)在石油工程領(lǐng)域中會有較大的應(yīng)用前景。
[Abstract]:In this study, the research progress of polyamide-amine, polyglycidyl and polyethyleneimine as metal nanoparticles stabilizers are introduced. Polyamide-amine hyperbranched polymers can be used as water shutoff agents and chemical oil removers. They can be used as both reducing and dispersing agents in metal nanoparticle reactors to stabilize the dispersion of metal nanoparticles. Polyglycidyl, which contains a lot of hydroxyl groups, can be modified to obtain amphiphilic nano-capsules with good biocompatibility and can be used as a high quality demulsifier for crude oil. The particle size of metal nanoparticles can be controlled by their relative molecular weight, and polyvinyleneimide-amine has a large number of amine functional groups, which provides abundant sites for coordination of metal ions, and its encapsulated metal nanoparticles can be used as temperature-sensitive materials. In combination with the structural controllability of hyperbranched polymers and the excellent catalytic performance of nanometallic materials, these materials will have great application prospects in petroleum engineering.
