Tg Confinement Effect of Random Copolymers of 4- tert-Butylstyrene and 4-Acetoxystyrene with Different Compositions
{{output}}
We observe that the Tg confinement effect of polymer films can saturate with polymer-substrate interaction. Thickness dependences of the glass transition temperature, Tg(h0), of random copolymer films of 4-tert-butylstyrene (TBS) and 4-acetoxystyrene (AS) supp... ...
