Action mechanism of different fibres on structure and property of plated coatings

Abstract

This paper tentatively chooses polyester, bamboo fibre and cotton as solution carrier during the plating process. The morphology, deposition rate, phase structure, hardness, friction and wear properties of coatings is characterised. Water absorbency, heat dissipation and electrical conductivity of three different solution carriers are analysed in order to study their action mechanism. The results show that the bamboo fibre presents the smoothest and compacts surface morphology and good water absorbency, which can ensure the supplement of solution. It also features larger electricity resistance and lower deposition rate, but fine grain, high hardness and good wear-resistance, all of which result in the best comprehensive performance. Cotton, with the best water absorbency, characterises higher hardness but poor uniformity and wear-resistance. Polyester carries the worst water absorbency, fast deposition rate, low hardness and better wear-resistance.

A superrobust superhydrophobic PSU composite coating with self-cleaning properties, wear resistance and corrosion resistance

“…PSU, a rigid material, can improve the hardness of the prepared coating, because wearability is proportional to hardness. 34 The melting molecular polymer intercalated into the MMT-PDMS gallery due to its special hierarchical lamellar structure. Meanwhile, the reaction between the carboxyl on the surface of PSU and the hydroxide radical of MMT-PDMS enhanced the interface adhesion force.…”
