A facile method for grafting functional hydrogel films on PTFE, PVDF, and TPX polymers

Abstract

The performance of polymeric materials in biomedical applications requires a judicious control of surface properties as it is directly related to cellular interactions and biocompatibility. The most desired chemical surface...

Achieving durable hydrophilic modification of polytetrafluoroethylene (PTFE) through organic/inorganic hybridization strategy

“…However, the long-term stability of grafting and production cost problems are remaining challenges to its industrial application. [23][24][25] The introduction of new groups by chemical modification is a conventional approach to achieve durable properties. 26,27 Over past decades, researchers have reported that PTFE can feasibly be etched by chemical reagents such as furan base solution, sodium-naphthalene solution, strong acid, and strong oxidizing salt.…”

Evaluation of Biocompatible Films Using Copolymers of N‐Vinylbenzamide with Cationic Moieties by Hydrolysis of N‐Vinylformamide

“…[ 24 ] In another example, a copolymer with a polycation and fluorine polymers were coated on fluorine polymers to introduce peptide on the surface. [ 25 ]…”

“…[24] In another example, a copolymer with a polycation and fluorine polymers were coated on fluorine polymers to introduce peptide on the surface. [25] On the other hand, polyphenylalanine is known as a biocompatible polymer. It has been used as the solid phase of HPLC [26] and peptide-like polymers.…”

Fabrication of poly(vinylidene fluoride)‐based composite powder coating with enhanced adhesion performance

“…This approach seeks to enhance the resistance against water penetration and improve the adhesion strength of the coating under “wet” conditions. By grafting suitable chemical compounds onto the PVDF matrix, researchers aim to create a protective barrier that effectively mitigates the adverse effects of water exposure 20–23 . Nonetheless, nearly all reported so far require the involvement of alkali pretreatment or rigorous condition during modified process, which makes it hardly possible for large‐scale production.…”
