In order to broaden the application range, PEEK has been modified by 1064nm-wavelength pulse laser, then deposited with Ni-P alloys electroless plating. The properties of metal layers on were characterized SEM, resistance tester and metallographic microscope, respectively. When laser energy density is relatively low (Q<60J·cm -2 ), there mainly photothermal effect surface substrate presents ...

Unprecedented water vapor uptake of 320% was demonstrated with SPEEK at an unexpectedly low degree sulfonation 19% due to the high S–S distance.

Abstract Osmotic energy, existing between solutions with different concentrations, is a sustainable and ecofriendly resource for solving energy issues. However, current membrane-based osmotic conversion technologies focus on electricity generation from an “open” system by directly mixing salt (NaCl) at room temperature. For the integrated utilization of thermal higher power output performance, ...
