Dette manuskript detaljer protokoller for at fabrikere en glat overflade med høj temperatur resistens. Vores forberedt overflade glat ejendom blev demonstreret ved at observere den let-glidende opførsel af en vanddråbe. Derefter, anti-befugtning af den forberedte glatte overflade på forskellige høje temperaturer blev undersøgt ved at deponere en vanddråbe på den varme overflade. Resultaterne viser at rede glatte overflade vedligeholdes sin glatte ejendom, selv når det var opvarmet til over 300 ° C. Vi har også...

Anti-friktion ved høje temperaturer til brug med væsker og bløde væv har modtaget betydelig interesse på grund af deres omfattende ansøgning potentielle i elektrokirurgiske instrumenter, motorer, rørledninger osv. 1 , 2 , 3 , 4. Bioinspired overflader, især superhydrophobic overflader, der betragtes som det ideelle valg på grund af deres fremragende anti-befugtning evner og selvrensende egenskaber5. I superhydrophobic overflader, bør muligheden for anti-befugtning tilskrives den låste luft i strukturen overflade. Men den superhydrophobic tilstand er ustabil, fordi det er i Cassie-Baxter stat6,7. Også, ved høje temperaturer, anti-befugtning for flydende dråber kan mislykkes på grund af befugtning staten overgangen fra Cassie-Baxter til Wenzel stat8. Denne befugtning overgang er foranlediget af små flydende droplet befugtning i strukturerne, som resulterer i manglende låse luft på plads.
For nylig, inspireret af de glatte egenskaber af peritome af den pitcher planten Nepenthes, Wong et al. rapporterede et koncept til at opbygge glatte overflader ved infusion af et smøremiddel til overfladen strukturer9,10 ,11. På grund af kapillær kraft, kan strukturerne fast holde smøremidlet på plads, ligesom i den låste luft lomme på superhydrophobic overflader. Smøremiddel og overfladen strukturer kan således, danne en stabil fast/flydende overflade. Når smøremidlet har en præferentiel affinitet for den overfladestruktur, flydende dråben på den sammensatte overflade kan glide let, med kun en meget lav kontakt vinkel hysterese (f.eks., ~ 2 °)12. Denne smøremiddel lag sætter også overflade har bemærkelsesværdige anti-befugtning kapaciteter13, viser store muligheder for medicinsk udstyr14,15. Men tidligere undersøgelser på glatte overflader primært fokuseret på forberedelserne til anvendelse ved stuetemperatur eller lave temperaturer. Der er meget få undersøgelser om forberedelse af glatte overflader med høj temperatur resistens. For eksempel, viste Zhang et al. , at den hurtig fordampning af smøremiddel hurtigt forårsager svigt af egenskaben glatte på selv lidt høje temperaturer16.
Glatte overflader med høj temperatur resistens kan udvide programmet potentiale; for eksempel kan de bruges som flydende hindringer for at mindske bløddele vedhæftning til elektrokirurgiske instrument tips. Under en kirurgisk operation opstår alvorlige bløddele vedhæftning på grund af den høje temperatur af de elektrokirurgiske instrument tips. Det bløde væv kan være forkullede, får det til at overholde instrument tip, som derefter tårer det bløde væv omkring tip17,18,19. Overholdt bløddelene elektrokirurgisk instrument spids påvirker negativt driften og også kan medføre svigt af hæmostase19,20. Disse effekter væsentligt skade folks sundhed og økonomiske interesser. Derfor er løse spørgsmålet om bløddele vedhæftning til elektrokirurgiske instrumenter meget presserende. I virkeligheden, giver glatte overflader mulighed for at løse dette problem.
Vi præsenterer her, en protokol for at fremstille glatte overflader fås ved høje temperaturer. Rustfrit stål blev valgt som den overflademateriale på grund af dens høj temperatur resistens. Rustfrit stål var ru af fotolitografi-assisteret kemisk ætsning. Derefter, overfladen var functionalized med en biokompatible materiale, saltvand octadecyltrichlorosilane (OTS)21,22,23,24. En glat overflade blev udarbejdet ved at tilføje silikone olie. Disse materialer aktiveret den glatte overflade for at opnå høj temperatur resistens. Egenskaben anti-befugtning ved høje temperaturer og de anti-friktion virkninger på blødt væv blev undersøgt. Resultaterne viser potentiale til at anvende glatte overflader til at løse anti-friktion ved høje temperaturer.

preparation and high-temperature anti-adhesion behavior of a slippery surface on stainless steel

Anti-friktion med høj temperatur resistens har en bred anvendelse potentielle i elektrokirurgiske instrumenter, motorer og rørledninger. En typisk anti-befugtning superhydrophobic overfladen ikke let når de udsættes for en høj temperatur væske. For nylig, Nepenthes-inspireret glatte overflader demonstrerede en ny måde at løse vedhæftning. Et smøremiddel lag på den glatte overflade kan fungere som en barriere mellem de frastødt materialer og den overfladestruktur. De glatte overflader i tidligere undersøgelser viste imidlertid sjældent høj temperatur resistens. Her, beskriver vi en protokol for forberedelse af glatte overflader med høj temperatur resistens. En fotolitografi-assisteret metode blev brugt til at fabrikere søjle strukturer på rustfrit stål. Af functionalizing overflade med saltvand, udarbejdede en glat overflade ved at tilføje silikone olie. Rede glatte overfladen vedligeholdes egenskaben anti-befugtning for vand, selv når overfladen var opvarmet til 300 ° C. Også, den glatte overflade udstillet store anti-friktion indvirkning på bløde væv ved høje temperaturer. Denne type af glatte overfladen på rustfrit stål har applikationer i medicinsk udstyr, mekanisk udstyr, osv.

Den glatte overflade var forberedt ved at tilføje silikone olie til OTS-belagt, kemisk ætset rustfrit stål. På grund af deres tilsvarende kemiske egenskaber, var overfladen helt chloroformvædet af silikone olie. Befugtning processen er vist i figur 1a. Den røde stiplede linje markerer linjen befugtning. Efter befugtning, kunne en synlig olie lag skelnes fra den tør overflade. Rede glatte overfladen glat ejendom blev undersøgt ved at deponere en vanddr...

Resultaterne viser, at de glatte overflader viste anti-befugtning for væsker og en bemærkelsesværdig anti-friktion effekt på bløde væv ved høje temperaturer.
