“…The produced composites exhibited an intercalated and/or exfoliated structure, which promoted improved thermal stability and mechanical properties compared with pure polymer. Prado et al [107] synthesized several PMMA/MMT composites by in-situ polymerization and using a chloroform solution under probe sonication. The prepared composites exhibited mixed and intercalated morphologies, which contributed to promising properties for optical electronic devices.…”

Recent advancements in material technologies have promoted the development of various preparation strategies and applications of novel polymer–nanoclay composites. Innovative synthesis pathways have resulted in novel polymer–nanoclay composites with improved properties, which have been successfully incorporated in diverse fields such as aerospace, automobile, construction, petroleum, biomedical and wastewater treatment. These composites are recognized as promising advanced materials due to their superior properties, such as enhanced density, strength, relatively large surface areas, high elastic modulus, flame retardancy, and thermomechanical/optoelectronic/magnetic properties. The primary focus of this review is to deliver an up-to-date overview of polymer–nanoclay composites along with their synthesis routes and applications. The discussion highlights potential future directions for this emerging field of research.

“…When the temperature reached up to 290 °C, the degradation rate of PCTFE-co-acrylate is 5wt%. By comparison, common polymethyl methacrylate (PMMA) matrix has 5% weight loss at 279 °C [22]. As a matter of fact, the fluorine components tend to be enriched on the surface of PCTFE-coacrylate.…”

With the continuous growth of industrialization, residual dyes degradation has been a hotspot in present research. Herein, the immobilization of ZnO into polychlorotrifluoroethylene-coacrylate (PCTFE-co-acrylate) matrix render hybrid film with good hydrophilicity and ageing resistance. We studied the effects of different ZnO/PCTFE-co-acrylate ratio on photocatalytic behavior under ultraviolet illumination. The best degradation ability of methylene blue (MB) was obtained for PZ-1 owe to Zn 2+ and defect levels, which achieved up to 96.3% at 120 min later. Meanwhile, concerned kinetics property was adequately explored, which match well with pseudofirst order reaction. Such a simple, green and convenient approach provides a high-performance hybrid film for dyes wastewater purification.

“…Kheroub et al [47] applied in-situ polymerization for the preparation of poly (furfural alcohol)/MMT compounds. The resulting composite has upgraded mechanical and thermal properties due to an intercalated or peel-able structure as compared to original polymers [48]. By use of in-situ polymerization and solution of trichloromethane in an environment of an ultrasonic probe Prado et al prepared many PMMA/MMT composites.…”

Clays are the naturally existing mineral having layered structures with at least one dimension in the nano-range that are economical and environment friendly. There exist two types of nanoclays, anionic and cationic, depending on the surface charge layered. Nanoclays have wide application in different areas for improving physical properties like heat resistance, mechanical strength and anticorrosion quality of the polymer matrix. Clay and its composite have promising applications including tissue engineering, petroleum, drug delivery, food packaging and enzyme immobilization. Due to their superior properties like flame retardancy, non-toxic, magnetic properties and large surface areas; hectorites and their composite are of great interest. The primary focus of this chapter is Composite Formation by in-situ polymerization of hectorite/clay materials and its application in different areas.
