Polymer Clay Nano-composites

Bionanocomposites are multifunctional materials, which contain biological origin and particles, have nanometer-scale dimensions (1–100 nm) and can be employed in a vast range of applications in fields like tissue engineering, electronic appliances, biosensors, regenerative medicine, drug delivery systems and food packaging due to their remarkable advantage of exhibiting biocompatibility, antibacterial activity, and biodegradability. To develop naturally biodegradable materials like bionanocomposites, several biopolymers are employed in recent years. Polysaccharides are made up of sugar molecules linked together by glycosidic bonds. These polymeric carbohydrates, which are the most prevalent polymers in nature, are gaining interests as a feasible replacement for synthetic polymers in nanocomposite materials manufacturing. Polysaccharides are promising matrix for the production of green nanocomposites due to their biodegradable nature and biocompatible qualities, hierarchical structure, and high film-forming ability. This chapter discusses the processing, properties, characterisation, and applications of bio-based nanocomposites with various polysaccharides functionalized by various nanofillers.

“…In another study, montmorillonite-chitosan-based nanocomposite also showed good biocompatibility and mucoadhesive properties in addition to their low solubility in acidic media. Biocompatibility of the above-mentioned composites has extensively been substantiated by aggregation, adhesion, and hemolysis experimentation [53,54] Table 1…”

2022

Clay-based biopolymers are among the most efficient and cost-effective composite materials that find applications in a variety of biomedical applications such as drug delivery. This chapter elaborates the different physical, chemical, and structural properties of clay biopolymeric composites, which makes them most reliable to use for the applications of drug delivery. The main focus of writing this chapter is to explore the composition, structural properties, and route of action of clay-based nanomaterials, along with elaborating the mechanism of the drug delivery system. The synthesis of clay-encapsulated drug formulation and their route of administration has been investigated in this chapter. Data for the synthesis of composites and in vitro study has also been included from the existing literature.

“…Scanning electron microscopy (SEM) imaging can reveal shape, topology, composition, and other details, as well as indicate if the clay has been correctly distributed inside the polymer matrix. There will be agglomeration if the additives are not dispersed well, which might lead to blockage of the percolation network and a lower the flame retardancy of the polymer composites [30].…”

Micro Clay/Nano Clay Polymer Composite Flame Retardant Applications

2022

The discovery of fire is one of the earliest and most significant achievements of man. However, it is a lethal power that has mostly stayed uncontrollable. Big fires occur practically daily and result in significant loss of life and property. The majority of the contents in the houses are flammable. Clothes, blankets, furniture, paper, synthetic polymeric materials, automobile and plane interiors, etc., all burn when the conditions are favorable. The addition of flame retardant to polymeric materials improves their flame retardancy and thermal stability. In this chapter, we will study the addition of micro clay/ nano clay to improve the flame retardancy of polymeric composites to make them feasible to be used in various potential applications.
