Plazemska obdelava polimerov: od osnov do industrijskih izzivov

 

izr. prof. dr. Alenka Vesel

Institut »Jožef Stefan«, Ljubljana, Slovenija

 

 

Polimeri so v sodobni družbi nepogrešljivi, vendar imajo površinske lastnosti, ki pogosto otežujejo njihovo uporabo. So namreč hidrofobni, imajo slabo omočljivost in slabe adhezijske lastnosti. V predavanju bom razkrila, kako lahko plazemska obdelava površin polimerov povsem spremeni njihove lastnosti, doda nove funkcionalne skupine, vpliva na morfologijo površin, izboljša adhezijo površin, poveča omočljivost in celo ustvari superhidrofilne površine. Skozi primere, meritve in razlago osnovnih fizikalno-kemijskih mehanizmov bom pokazala, kako deluje ta tehnologija, kateri plazemski delci so ključni, zakaj je pomembno poznavanje doz plazemskih radikalov in kako rezultate laboratorijskih raziskav prenesti v industrijsko prakso.

 

O predavateljici: Alenka Vesel je znanstvena svetnica na Institutu »Jožef Stefan«, kjer je vodja Odseka za tehnologijo površin, in izredna profesorica na Mednarodni podiplomski šoli Jožefa Stefana v Ljubljani.

Polymer plasma treatment: from basics to industrial challenges 

 

Assoc. Prof. Dr. Alenka Vesel

Jožef Stefan Institute, Ljubljana, Slovenia

 

 

Polymers are indispensable in modern society, but they have surface properties that often make their use difficult. Namely, they are hydrophobic, have poor wettability and poor adhesion properties. In this lecture, I will reveal how plasma treatment of polymer surfaces can completely change their properties, add new functional groups, affect surface morphology, improve surface adhesion, increase wettability and even create superhydrophilic surfaces. Through examples, measurements and explanation of basic physical-chemical mechanisms, I will show how this technology works, which plasma particles are crucial, why it is important to know the doses of plasma radicals and how to transfer the results of laboratory research into industrial practice.

 

About the lecturer: Alenka Vesel is a scientific councilor at the Jožef Stefan Institute, where she heads the Surface Engineering department, and an associate professor at the Jožef Stefan International Postgraduate School in Ljubljana.
