PolyDADMAC-based polymers are a class of synthetic polymers that incorporate poly(diallyldimethylammonium chloride) (polyDADMAC) units into their structure. These polymers are characterized by their cationic nature, which arises from the presence of quaternary ammonium groups along the polymer backbone. The cationic nature of polyDADMAC-based polymers makes them useful in various applications, including water treatment, coatings, and biomedical applications.

In water treatment, polyDADMAC-based polymers are employed as coagulants and flocculants. The cationic charges on the polymer chains facilitate the aggregation of negatively charged particles, such as colloids and suspended solids, into larger, more easily removable flocs. This process is crucial in the treatment of wastewater and drinking water, where the removal of impurities is essential for maintaining water quality.

In coatings, polyDADMAC-based polymers are used to enhance the adhesion and durability of coatings on various substrates. The cationic charges on the polymer chains can interact with anionic groups on the substrate surface, promoting strong adhesion. Additionally, the cationic nature of these polymers can provide antimicrobial properties, making them useful in applications where resistance to microbial growth is required.

In biomedical applications, polyDADMAC-based polymers are explored for their potential in drug delivery and tissue engineering. The cationic charges on the polymer chains can interact with negatively charged biomolecules, such as DNA and proteins, facilitating their encapsulation and controlled release. Furthermore, these polymers can be functionalized with bioactive molecules to promote cell adhesion, proliferation, and differentiation, making them valuable in tissue engineering and regenerative medicine.

The synthesis of polyDADMAC-based polymers typically involves the polymerization of diallyldimethylammonium chloride (DADMAC) monomers using various polymerization techniques, such as free radical polymerization or cationic ring-opening polymerization. The resulting polymers can be further modified through chemical or physical methods to tailor their properties for specific applications.
