RESUMO
Durability is still the main issue hindering the practical applications of superhydrophobic surfaces. In the case of superhydrophobic coatings, employing nanoparticles for constructing and retaining superhydrophobic surfaces without lowering the robustness is still a conundrum. Herein, inspired by concrete, which has a high filler portion and high robustness, we fabricated a superhydrophobic coating using a synthesized hydrophobic organic/inorganic hybrid resin and categorized micro/nano fillers with varying sizes. The hybrid resin improved the hydrophobicity and robustness of the coating. Also, by optimizing the content of categorized wearable (silica sand with varying sizes)/functional (aluminum nanoparticles)/low-surface-energy (PTFE) phases, the prepared superhydrophobic surfaces could achieve long abrasion distance coupled with a high retention rate. Also, the prepared sample retained its superhydrophobicity after abrasion by sandpaper (180 grit) for 10 m under a pressure as high as 22.5 kPa or 600 grit sandpaper for 12.8 m under the same pressure or when impacted by 1400 g sand particles from 30 cm. Also, the coating had a strong adhesion of 5B with the substrate. Thus, the designed attractive materials have the potential for self-cleaning, anti-icing, and anti-fouling applications in industries.
RESUMO
Objective To investigate and analyze the clinical efficacy of psychological intervention in the treatment of uterine atony postpartum hemorrhage and its influence on the quality of life. Methods 100 cases of uterine atony postpartum hemorrhage were selected in our hospital from March 2015 to September 2016.The subjects were randomly divided into the control group and the experimental group, 50 cases in each group. The patients in the control group were treated with oxytocin, and the experimental group was treated with Xinmu Pei combined with psychological intervention.The treatment effect and quality of life total score were compared between two groups. Results After the corresponding treatment, the effective rate of the experimental group was 92.0％, which was significantly higher than that of the control group(72.0％), the difference was statistically significant (P<0.05). The total score of quality of life in the experimental group was (75.2±11.2) points, significantly higher than that of the control group (64.2±9.3), the difference was statistically significant (P<0.05). Conclusion The clinical effect of psychological intervention of hemabate in treatment of postpartum hemorrhage maternal, can improve the therapeutic effect to a great extent, improve the quality of life of patients, with further clinical promotion and application significance.
