Plasma Modification of Surface Wettability and Morphology for Optimization of the Interactions Involved in Blood Constituents Spreading on Some Novel Copolyimide Films

Semi-alicyclic polyimides as potential membrane oxygenators: Rheological implications on film processing, morphology and blood compatibility

“…Among them, literature [34] highlights the importance of the surface free energy in moderating the protein and cell interactions, and finally the host response. In previous works [18][19][20][21][22], the hemocompatibility was assessed by calculation of the work of spreading of the blood (including its cells and proteins) on PI surface. Here, we used another approach that involves direct contact of blood with PI film surface.…”

“…All these reports are focused on fully aromatic PIs of commercial nature [12] or synthesized from monomers containing fluorine and/or sulfone groups [14][15][16][17]. Since 2012, our research group initiated the studies on hemocompatibility of PI based on aliphatic sequences [18][19][20][21][22]. A particular attention was ascribed to PIs prepared from 5-(2,5-dioxotetrahydrofuryl)-3-methyl-3-cyclohexene-1,2-dicarboxylic acid anhydride (EPI), which was proven to have good biocompatibility with dental or dermal tissues [23,24].…”

Effects of O2Plasma Treatment on the Hydrophilic/hydrophobic Contrast of Film Substrates

“…초발수성을 부여하는 방법은 대 체적으로 고체표면에 "연잎효과"를 재현하는 것으로 고체 의 표면에너지와 표면요철을 제어함으로써 가능하다. 고체 표면에 요철을 부여하는 방법은 화학적 에칭 [2]과 플라즈 마 에칭이 널리 사용되고 있는데, 이중에서 플라즈마에 의 한 방법이 여러 분야에서 광범위하게 사용된다 [3][4][5][6] (1) 참고문헌…”

From superhydrophilic to superhydrophobic surfaces by means of polymeric Layer-by-Layer films

“…These techniques are combined with reagents such as Fluoroalkylsilane (FAS), Perfluorodecylsilane (PDS), Poly(tetrafluoroethalene) (PTFE), Alkyl-ketene dimers (AKDs) or Poly(alkylpyrrole) to improve the hydrophobicity. To produce this kind of surfaces, it is necessary to obtain a low energy of interaction with water [32]. Groups such as alkyl or fluorinated are very interesting for creating superhydrophobic surfaces because they satisfy this condition and water is very strongly repelled by these surfaces [33].…”
