Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Wound dressing, a powerful tool for repairing and protecting injured skin from secondary damage, has been widely manufactured. However, the design of wound dressings with waterproofness, breathability, mechanical robustness, and outstanding biocompatibility remains a challenge owing to the imbalance between the multiple desirable properties. Herein, a strategy is proposed to fabricate biocompatible membranes via a facile one-step electrospinning method. Polydimethylsiloxane (PDMS)-based polyurethane (Si-PU) is successfully prepared to construct durable hydrophobic surfaces to endow the membrane with high hydrophobicity (water contact angle = 141.0°). The porous structure is optimized by adjusting the solution concentration and heat treatment temperature, enabling the membrane with an optimum water vapor transmission rate of 8.2 kg·m−2·h−1, a hydrostatic pressure of 52.3 kPa (approximately 14.1 times that of the PU fibrous membrane), and an enhanced tensile stress of 6.60 MPa. Furthermore, the membrane can be used within a very wide temperature range from –123°C to 160°C due to the low glass transition temperature and superior thermal stability. Importantly, both in vitro and in vivo experiments verified the excellent biocompatibility and negligible toxicity to normal cells and mice skin, as characterized by hematoxylin and eosin (H&E) and Masson staining. Our work presents a new approach for designing waterproof, and breathable, mechanical robust biomaterials and enhancing the performance and functionality of biomaterials in biomedical fields, especially in wound dressing applications.
