Abstract

Hybrid interpolymeric complexes (HICs) compose a new class of materials. Such complex consists of inorganic and organic complexing polymers bonded one with another by noncovalent interactions like DNA double helix. Inorganic chain polymers stabilized in organic matrix can be produced from HICs through solid state synthethis. These materials can be used in different applications.

8.1 Introduction

8.1.1 Historical Overview

Hybrid interpolymeric complexes (HICs) are a new class of materials. Such complex consists of inorganic and organic polymers bonded one with another by noncovalent interactions. Earlier, organic interpolymeric complexes were known. The most prominent representative of such organic complexes is deoxyribonucleic acid (DNA). It is known that DNA complex includes two polymeric chains bonded through complementary nucleotide groups. HIC can be viewed to some extent as an analog of DNA where one component is inorganic polymer. The existence of HICs as a new class of materials was predicted for the first time in 2013 [1]. Earlier, only two representatives of this class were discussed. One of them is a complex of copper hydroxide with polyvinyl alcohol (PVA) (–CH₂–CHOH–)n [2]. Then, well-known ...
