Renewable and biodegradable UV-blocking films are in high demand for the increasing
need of sustainable environment. Lignin can offer significant UV absorption, but it …

Lignins from pulp mills and biorefineries will gain increasing commercial importance in the
next years. Their utilisation in polyolefin blends is of growing research interest as it offers a …

An organosolv lignin, extracted in organic acid media, named Biolignin™, was acetylated
with acetic anhydride in supercritical carbon dioxide (scCO 2). The effect of moisture and …

A novel lignosilicate (LS) composite was synthesized from pre-extracted (hot water, 80%
ethanol, 0.3 N NaOH) lignin of rice husk (RH) using TEOS as matrix. The extracted lignins …

In the present study we synthesized lignin-tetra ethoxysilane (TEOS) nanocomposite and
characterized it using UV-spectroscopy, Fourier Transform Infra-red spectroscopy (FTIR) …

The intrinsic properties of raw lignin make it difficult to be used directly for advanced
applications. To overcome these problems, there is a need to functionalize lignin and endow …

Natural fiber filled/reinforced composite materials are heavily studied in the academy and
industry. Lignin is both a natural filling material and a side product of cellulosic bioethanol …

The use of natural fibers, particularly those of lignocellulosic composition, as reinforcement
in polyolefin matrices has been the object of numerous studies in the last decade. It has …
