Abstract
A formulation for coating surfaces, for example gloves, with a tacky film comprises a hydrophobically modified biopolymer, where the hydrophobic modifications of the biopolymer correspond to between 1 and 90% of available functional groups, a plasticizer, and a volatile solvent. The formulation quickly dries into a tacky film that provides an enhanced friction of the surface.
Claims20
A formulation, comprising:
- a hydrophobically modified biopolymer, where between 1 and 90% of available functional groups of the biopolymer are covalently attached to a hydrophobic moiety, a plasticizer, and a volatile solvent;
- wherein the formulation quickly dries into a tacky film.
A tacky biopolymer film, comprising:
- a dried tacky hydrophobically modified biopolymer;
- where between 1 and 90% of available functional groups of the biopolymer are covalently attached to a hydrophobic moiety, a plasticizer, and an enhancer.
A method of using a tacky biopolymer film, comprising:
- applying a tacky biopolymer film solution comprising a hydrophobically modified biopolymer, where between 1 and 90% of available functional groups of the biopolymer are covalently attached to a hydrophobic moiety, a plasticizer, and a solvent to a surface;
- allowing the tacky biopolymer film solution to dry.
