“…Images with similar morphology were obtained for granular envelope region. This observation corroborates previous works reporting that upon a-C:H coating, using either 1-butene [7] or 1,3-butadiene [8] as precursors gas, an homogeneous surface composed mainly of irregular oval shaped structures was observed on both matrix and granular regions. However, the size of surface features varied according to the precursor gas.…”

“…[6] A new approach to overcome this difficulty might be to protect the starch based materials from humidity changes with a thin polymeric layer, deposited by plasma polymerization. [7][8][9] In the present work, we studied the possibility of reducing the water sensitivity of cornstarch films by depositing carbon coatings from hydrocarbon gases. A subsequent surface treatment with sulphur hexafluoride (SF 6 ) on the amorphous carbon coated films was also evaluated.…”

Summary: In this work, a new coating strategy was successfully developed and promising results indicate a significant reduction of the water sensibility of cornstarch films coated by chemical vapour deposition (CVD). Amorphous carbon coatings (a-C:H) produced from methane (CH 4 ) were submitted to different sulphur hexafluoride plasma treatments. The best results were obtained for cornstarch films coated with a 50 nm-thick CH 4 plasma coating and treated with SF 6 for 60 s. This surface modification led to a significant increase in the surface hydrophobicity, with measured contact angle of 858. Atomic force microscopy (AFM) was used to evaluate local surface modifications upon the a-C:H coating and after the SF 6 plasma treatment. Results indicate that the cornstarch films were homogeneously coated using CH 4 . SF 6 treatment led to a plasma etching of the surface, changing completely the observed morphology. Fluorine was incorporated to the surface.

In the present work, D‐isosorbide and 1,3‐propanediol are proposed as alternative plasticizers obtained from renewable resources. Plasticized starch films were prepared by solvent casting method. The influence of using different “green” plasticizers in the final properties of starch‐based films was analyzed. Besides, the characterization of the films was also performed after storage time in order to evaluate the effect of the plasticizer on aging. UV‐spectrophotometry results showed better optical properties for both glycerol and D‐isosorbide films with higher transparency. The thermal and mechanical properties resulted influenced by the nature of the plasticizer. It was demonstrated that water vapor permeability was governed by the starch‐water interactions, whereas the oxygen permeability depended on the plasticizer's nature. The storage time affected the surface, mechanical, and thermal properties of the plasticized starch films. Atomic force microscopy results concluded that the topography of the films changed due to aging. The use of D‐isosorbide as plasticizer reduced the evolution of the mentioned properties and enhanced the reliability of the material. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
