Superhydrophobic coating of silica with photoluminescence properties synthesized from rice husk ash
MUM Junaidi, SAH Azaman, NNR Ahmad… - Progress in Organic …, 2017 - Elsevier
Water penetration into concrete can cause the degradation of concrete strength, leading into
structure failure. Superhydrophobic coatings on concrete received tremendous attention in
the recent years as these coatings repel water like lotus leaves. In this work, rice husk ash
(RHA) was used to prepare the superhydrophobic coating. Rice husk was calcined at 550°
C and 650° C to form silica particles with a small amount of carbon residue. RHA 550
sample showed slightly higher photoluminescence (PL) intensity than RHA 660 sample as …
