“…An alternative approach to enhancing the wetability of hydrophobic polymers is plasma treatment. Even short plasma treatment times have been shown to result in a significant reduction in contact angles with water for aliphatic poly(ketones), 25 poly(etheretherketone) 26 and even for poly(tetrafluoroethylene). 27 When argon plasma is used, incorporation of oxygen into the material can either occur via reaction of oxygen containing species during plasma treatment (i.e., H2O, O2) 28 or by reaction of surface free radicals with atmospheric oxygen upon exposure to air after plasma treatment.…”

“…29 The introduction of oxygen into the material results in the formation of polar groups that enhance the interaction with water. 25,29 Plasma treatment is inexpensive, cheap, and scalable, but there are no examples, to our knowledge, of its use to modify organic photocatalysts. Here we report a new approach to modifying conjugated polymer films by using plasma treatment.…”

Novel functional poly(1,4‐ketone) terpolymers have been prepared by the Pd(II)‐catalyzed alternating copolymerization of carbon monoxide, an apolar alkene and functional termonomers 2‐allylphenol 1 and 2‐allylanisole 2, respectively. In these experiments [Pd(DPPP)(CH3CN)2](BF4)2 3 served as the catalyst precursor, activated by the addition of a defined amount of methanol. The thermal as well as the physical properties of the obtained functional materials were governed by (a) the concentration of the termonomer within the polymer and (b) the chemical structure of the 1‐alkene. Terpolymers containing 1, ethene and carbon monoxide, where 1 is incorporated up to 8.6 mol‐% relative to CO displayed a semi‐crystalline morphology. Crystallinity and melting were strongly depending on the concentration of the functional component. If propene was applied instead of ethene, amorphous polymers were formed, which offer relatively high glass transition temperatures (up to 141.7°C). Apolar functional materials with a broad range of glass transition temperatures as well as tunable surface polarity result from the use of higher 1‐alkenes.

“…PK material is cheaper than general engineering plastics such as polyamide, polyester, and polycarbonate. 11,12 In addition, there is great interest in developing environmentally friendly materials to replace the conventional engineering plastics. 13 However, there have been no reported biomedical applications of these biomaterials, despite their several advantages.…”

Biomaterials for clinical applications such as medical and implant devices require evaluation to determine their biocompatibility. This study aimed to evaluate the initial biological safety of polyketone (PK) polymers, which have potential use as biomaterials. It presents results from cytotoxicity and genotoxicity assays and tests determining the levels of skin irritation, sensitization, and acute systemic toxicity caused by PK. The PK polymers showed no cytotoxicity, genotoxicity, allergenicity, irritancy, and systemic toxicity. These results indicate that the PK polymers are potentially biological safe and could be used to replace non-degradable polymeric biomaterials.
