CuO/Cu based superhydrophobic and self-cleaning surfaces
He, Zhiwei; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2016)CuO/Cu based superhydrophobic surfaces with ordered micro/nanostructures have been prepared via a solution-immersion process combining with photolithography and argon ion beam etching. CuO nanoneedles grow only inside ... -
Design and preparation of icephobic PDMS-based coatings by introducing an aqueous lubricating layer and macro-crack initiators at the ice-substrate interface
He, Zhiwei; Zhuo, Yizhi; Wang, Feng; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2020)Preventing ice accretion on exposed surfaces is important to the operational performance of various facilities and devices. As time elapses and temperature lowers sufficiently, ice accretion becomes inevitable. Herein, we ... -
Design and Preparation of Sandwich-Like Polydimethylsiloxane (PDMS) Sponges with Super-Low Ice Adhesion
He, Zhiwei; Zhuo, Yizhi; He, Jianying; Zhang, Zhiliang (Journal article, 2018)The mitigation of ice on exposed surfaces is of great importance to many aspects of life. Ice accretion, however, is unavoidable as time elapses and temperature lowers sufficiently. One practical solution is to reduce ice ... -
Design of Icephobic Surfaces by Lowering Ice Adhesion Strength: A Mini Review
He, Zhiwei; Zhuo, Yizhi; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2021)Ice accretion can lead to severe consequences in daily life and sometimes catastrophic events. To mitigate the hazard of icing, passive icephobic surfaces have drawn widespread attentions because of their abilities in ... -
Dynamic anti-icing surfaces (DAIS)
Wang, Feng; Zhuo, Yizhi; He, Zhiwei; Xiao, Senbo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2021)Remarkable progresses have been made in surface icephobicity in the recent years. The mainstream standpoint of the reported anti-icing surfaces yet only considers the ice-substrate interface and its adjacent regions being ... -
Enhancing the mechanical durability of icephobic surfaces by introducing autonomous self-healing function
Zhuo, Yizhi; Håkonsen, Verner; He, Zhiwei; Xiao, Senbo; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2018)Ice accretion presents a severe risk for human safety. Despite great efforts for developing icephobic surfaces (the surface with an ice adhesion strength below 100 kPa) have been devoted, expanding the lifetime of ... -
Nanotechnology for Anti-Icing Application: From Superhydrophobic Surfaces to Super-Low Ice Adhesion Surfaces
He, Zhiwei (Doctoral theses at NTNU;2016:348, Doctoral thesis, 2016)Within the past two decades, the Arctic regions have attracted significant attentions from all over the world because of appraisals on an undiscovered wealth of petroleum and mineral resources. Harsh environmental challenges, ... -
Room Temperature Characteristics of Polymer-Based Low Ice Adhesion Surfaces
He, Zhiwei; Vågenes, Elisabeth Tanami; Delabahan, Chrisrosemarie; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2017)Ice adhesion is mainly dictated by surface properties, and water wettability is frequently correlated with ice adhesion strength. However, these established correlations are limited to high ice adhesion and become invalid ... -
Selective growth of metallic nanostructures on microstructured copper substrate in solution
He, Zhiwei; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2015)Selective growth of metallic micro/nanostructures on desired micropatterns was achieved via a simple solution-immersion process. Interestingly, metallic micro/nanostructures directly grow only inside hollow copper micropatterns ... -
Understanding the role of hollow sub-surface structures in reducing ice adhesion strength
He, Zhiwei; Zhuo, Yizhi; Wang, Feng; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2019)The accretion of ice on exposed surfaces infers detrimental effects on many aspects of life and technology. Passive icephobic coatings, designed by strategies towards lowering ice adhesion to mitigate the icing problems, ...
