Three different wet and cold-plasma treatments were used in order to create hydrophobic layers on beans surface. Hexamethyldisilazane (HDMS) was the precursor solution for based organosilicon composition film formation. Structures such as SiCH3 and Si2CH2 were identified as composing the surface after plasma treatments. Ultra-violet exposure promoted corsslinking in the polymeric film but no interference in hydrophobic properties was found. Combination of HDMS vapor plus 5 minutes plasma showed the best result in avoiding beans germination in wet environmental condition. |
