“…[17][18][19][20][21][22] Meanwhile, DMDAAC is also usually copolymerized with other unsaturated monomers to form cationic or amphoteric polymers. [23][24][25][26][27][28][29][30][31] During the preparation of DMDAAC-based homopolymer and copolymer, the solution polymerization, inverse emulsion polymerization, and dispersion polymerization are the common methods. In our previous work, 32 copolymer of DMDAAC and a nonionic block polyether macromonomer (PEP-65) was prepared as a novel reverse demulsifier, which has both advantages of cationic reverse demulsifier and nonionic reverse demulsifier and has very well reverse demulsification performance.…”

Copolymerization of cationic monomer and nonionic macromonomer in water-ether mixture solution is useful for preparing the functional polymer. Copolymer of diallyldimethylammonium chloride (DMDAAC) and a nonionic block polyether macromonomer (PEP-65) has been found that has very well reverse demulsification performance, but the polymerization phenomenon cannot be described by any reported polymerization method. In this paper, the copolymerization behavior including polymer mechanism, polymerization kinetics, and reactivity rate of DMDAAC and PEP-65 in the mixture solution of water and propylene glycol methyl ether (PGME) was studied for explaining the special copolymerization phenomenon and its flotation performance for treating oily wastewater was also investigated. The results showed that DMDAAC-PEP-65 copolymerization in water-PGME mixture solution has four stages and has both characteristics of emulsion polymerization and dispersion polymerization. In addition, the copolymer also has excellent flotation performance.

The printing of polyester (PET) fabrics using binders and disperse dyes is an environmentally less harmful technique due to the exclusion of water‐intensive washing processes. Unfortunately, the conventional polyacrylate (PA) binders are inapplicable for this printing technique as the high PA‐disperse dye compatibility restrains the migration of disperse dye molecules from binder films into PET fabrics. Herein, we demonstrate a rational design and synthesis of novel PA binders by copolymerizing fluorosilicone monomers with multi‐vinyl groups for the sustainable printing of PET fabrics. The incorporated fluorosilicone functionalities significantly decrease the solubility parameter of PA, facilitating the dye molecules migration toward PET fabrics. Meanwhile, the crosslink structure formed via vinyl groups restrains the migration of polymer chains and thus allows for the anchor of F/Si segments, enabling the continuous migration of disperse dyes. As a result, both the utilization ratio of disperse dyes and the color yield and fastness of printed PET fabrics are substantially improved. Moreover, the washing‐free printing process using the developed binder can reduce 73% of water consumption, 74% of energy input, and 100% of wastewater discharge over the traditional printing process. Our study may provide insights into rational design of binders for the sustainable printing of PET fabrics.

Diseases and complications related to catheter materials are severe problems in biomedical material applications, increasing the infection risk and medical expenses. Therefore, there is an enormous demand for catheter materials with antibacterial and antifouling properties. Considering this, in this work, we developed an approach of constructing antibacterial surfaces on polyurethane (PU) via surface-initiated atom transfer radical polymerization (SI-ATRP). A variety of cationic polymers were grafted on PU. The biocompatibility and antifouling properties of all resulting materials were evaluated and compared. We also used a theoretical algorithm to investigate the anticoagulant mechanism of our PU-based grafts. The hemocompatibility and anti-biofouling performance improved at a 86–112 μg/cm2 grafting density. The theoretical simulation demonstrated that the in vivo anti-fouling performance and optimal biocompatibility of our PU-based materials could be achieved at a 20% grafting degree. We also discuss the mechanism responsible for the hemocompatibility of the cationic brushes fabricated in this work. The results reported in this paper provide insights and novel ideas on material design for applications related to medical catheters.
