Microwave-Assisted Aqueous Polyimidization Using High-Throughput Techniques

Geomimetics and Extreme Biomimetics Inspired by Hydrothermal Systems-What Can We Learn from Nature for Materials Synthesis?

'Extreme biomimetics' and 'geomimetics' are relatively recent fields of materials chemistry. Both take inspiration from natural materials for generating novel synthetic materials or enhanced properties in known materials. In geomimetics, the source of inspiration is geological systems, while extreme biomimetics is motivated by organisms operating in-from an anthropocentric point of view-extreme conditions. This review article focuses on geomimetic and extreme biomimetic hydrothermal synthesis. Since hydrothermal preparative chemistry typically uses nothing but water and the required precursors, the field belongs to the research area of 'green materials chemistry'. Geomimetics, on the one hand, takes inspiration from natural materials formation. Extreme Biomimetics, on the other hand, is inspired by materials found in extremophile organisms, instead of aiming to implement their actual biosynthesis. In this contribution, both extreme biomimetics and geomimetics are first defined, and further critically discussed on the basis of recent, selected examples. Moreover, the necessity for the two closely related fields as well their prospects are commented on.

Water-borne Polyimides via Microwave-assisted Polymerization

In the present study, the synthesis of high molecular weight polyimides was conducted in water using microwave irradiation. High molecular weight polymers were obtained after only 5 min of reaction time. The influence of different experimental parameters is discussed in connection with a thorough characterization of the synthesized polymers. From these polymers, self-supporting films were obtained.

Recent Advances in Microwave-Assisted Polymer Synthesis

In the past few years the use of microwave irradiation in polymer science has become a well-established technique to drive and promote chemical reactions. The main advantages of microwave heating are a strong reduction in reaction time and a high potential to contribute to green and sustainable chemistry. This article provides a short review of recent examples in the field of microwave-assisted polymer synthesis with special emphasis on radical polymerizations, step-growth polymerizations, ring-opening polymerizations, and polymer modifications.
