Thermodynamic and dynamic characteristics of hydroxypropylmethylcellulose adsorbed films at the air-water interface

Surface pressure isotherms and structural and surface dilatational properties of three hydroxypropylmethycelluloses (HPMCs, called E4M, E50LV, and F4M) adsorbed films at the air-water interface were determined. In this work we present evidence that HPMC molecules are able to diffuse and saturate the...
