Nanocomposites Based on Acrylic Oligomers and Modified Montmorillonite

Abstract

This comprehensive review encompasses a comprehensive analysis of nearly all established methodologies developed within the last 15-20 years to fabricate silicate/polymer nanocomposites based on acrylic oligomers and modified montmorillonite. The review thoroughly examines the diverse strategies employed to create these specific nanocomposites, categorizing them according to the distinct methods employed for mineral modification. The review systematically investigates three principal avenues of layered silicate modification. The first avenue involves the utilization of montmorillonite which has been modified with alkylammonium surfactants, shedding light on the intricacies and outcomes associated with this approach. The second avenue focuses on montmorillonite modification achieved through photopolymerization initiators, exploring the nuances and advancements within this context. The third avenue delves into the functionalization of montmorillonite with reactive groups, offering a comprehensive evaluation of this avenue’s potential and limitations. Each direction is dissected in terms of its distinctive advantages and drawbacks, contributing to a thorough understanding of the factors influencing the choice of a particular approach. This multidimensional exploration allows for a well-informed consideration of the most suitable method for a given application. By presenting a holistic perspective on the various methodologies, advantages, and challenges, the review aids in enhancing the collective understanding of this specialized area and promoting further advancements in the development of innovative silicate/polymer nanocomposites. This review also encompasses a comprehensive exploration of fundamental techniques instrumental in studying these intricate materials. The review also includes a number of basic methods used to study polymer/silicate nanocomposites. The main ones are small-angle X-ray scattering SAXS, X-ray diffraction XRD, transmission electron microscopy TEM, Scanning electron microscopy SEM, Dynamic mechanical analysis DMA and Dynamic mechanical thermal analysis DMTA. By illuminating the investigative tools used to unveil the structural and mechanical intricacies of these materials, the review empowers researchers to make informed decisions, advance their research, and contribute to the continued evolution of nanocomposite science.
