Micellar Polymers with Hydrocarbon and Fluorocarbon Hydrophobic Chains. A Strategy to Multicompartment Micelles

Macromolecules, 2002
Cationic ionenes bearing hydrophobic side chains were synthesized, which behave as micellar polymers of the polysoap type. The hydrophobic chains were either hydrocarbons or fluorocarbons, or a mixture of both, in the form of statistical as well as block

Surface Enrichment of Fluorocarbon End-Capped Polymers with Different Fluorocarbon Lengths

Journal of Nanoscience and Nanotechnology, 2016
This study investigated the surface structure of fluorocarbon end-capped l-poly(lactide)s (F-PLLA) with different fluorocarbon lengths by electron spectroscopy for chemical analysis (ESCA). Fluorocarbon chains of three lengths (F(CF2)n(CH2)2, where n = 6, 8, and 10) have been synthesized as the terminal group to PLLA.

Diffusion of gases in fluorocarbon polymers

Journal of Applied Polymer Science, 1963
AbstractThe diffusion and solubility coefficients and their temperature coefficients of several gases in fluorocarbon polymers were measured by a spring balance and radiotracer method. The activation energies of small molecule diffusion in polytetrafluoroethylene increase with the diffusate molecular diameter squared.

Surface Modification of Fluorocarbon Polymers by Synchrotron Radiation

Japanese Journal of Applied Physics, 2003
Fluorocarbon polymers are fluorishingly used as the material for industry from some characteristic advantages - chemical stability, thermal stability, excellent electric property and so on. One of other characteristics of fluorocarbon polymers was hydrophobicity of these surfaces, and fluorocarbon polymers were applicable to various industrial yields ...

Ultraviolet Photoablation of a Plasma-Synthesized Fluorocarbon Polymer

Optical Society of America Annual Meeting, 1990
Plasma polymerized tetrafluoroethylene (PPTFE) is shown to undergo efficient 248 nm excimer laser ablation. The principle difference between this material and the analogous polytetrafluoroethylene (PTFE), which results in only poor quality ablation, is PPTFE's much greater absorption coefficient.

A synthesis for SF5 substituted fluorocarbon polymers

Journal of Polymer Science Part C: Polymer Letters, 1990
Synthesis of both hydrocarbon and perfluorocarbon vinyl polymers containing the SF5 group have been accomplished by the reaction of elemental fluorine with poly (S-vinyl-O-t-butylthiocar bonate(. The resulting linear polymers have pendant SF5 groups with similar structures to polytetrafluoroethylene and polyethylene.

Pretreatments of Hydrocarbon and Fluorocarbon Polymers

The Journal of Adhesion, 1992
Abstract Pretreatments of polyolefins and fluoropolymers are usually necessary to achieve satisfactory adhesion for bonding and related technologies. In this paper results for various pretreatments of these polymers are presented. These are the treatment of polyolefins with aqueous reagents, dilute fluorine and a natural gas flame, the treatment of ...

Hydrocarbon versus Fluorocarbon in the Electrodeposition of Superhydrophobic Polymer Films

Langmuir, 2010
To elaborate on superhydrophobic surfaces, we report the electrochemical synthesis, surface morphology, and wettability of hydrocarbon conductive polymer films obtained by the electrodeposition of polythiophene, poly(3,4-ethylenedioxythiophene) (i.e., PEDOT), and poly(3,4-ethylenedioxypyrrole) (i.e., PEDOP) derivatives.
