Any newer methods which reduces the water absorption property of bio-fibres? Whether it will succeeds in the hydrophilic nature of the fibres
One of my aim is to find a proper solution, as we know that hydrophilic nature of bio-composites is a biggest issue in the development and utilization of the composites when coming into the part of application and another challenge when it comes with increasing the strength of the fibre and surface preparation for the effective bonding with the resin through chemical treatments.
Chemical treatments such as Alkalization, acetalization etc are older methods which will reduce the water absorption nature to a particular extent. I found this methods are not that much good during my experimentation.
Looking for favorable answers. Relevant to the topic.
Please comment only if you have experience on this field.
I'm also further looking for my doctoral studies in bio-composites. If anyone working this area i would like to join with you
Thanking you

Hi MR. Linto,
you are recommended to use Graphene and Graphene Oxide dispersion in water soluble state and after coating on bio-polymer and natural fibers and finally covert into GO coated film into rGO which is Super-hydrophobic in nature to reduce or overcome the water absorption kinetics. May Also use Low to high (Mw) Polyurethane (PU) coatings with GO/rGO. Regards, wish you best of luck in your experiments
Thank you so much Mr. Ali Nazakat Khoso.
Could you please provide me with some attachments regarding the process.
Hi,
I have summarized many of the surface treatment methods. Few of it may be helpful to you.
