Polyurethanes (PUs) are a class of versatile materials with great potential for use in different
applications, especially based on their structure–property relationships. Their specific …

The development of viable alternatives to petroleum-based polymeric materials is a
compelling contemporary challenge attributable to environmental concerns and the effects …

With development of industrial activities, a lot of oil pollution is released to water
environment. As such, superhydrophobic oil adsorption materials with reusability are …

Polyurethane foams, are highly demanded in many applications and their use is increasing
incessantly. Besides these traditional applications, recently polyurethane foams with …

Polyurethanes foams (PUF) are used in a wide variety of applications, therefore the quantity
of the PUF residues generated is an ecological and environmental problem. Hence, the …

Thermoplastic polyurethanes (TPUs) materials are obtained by the reaction of polyol (ether‐,
ester‐, and carbonate‐based diols with average molecular weight in the range from 1,000 to …

The present study describes the influence of the concentration of lignin when used as a filler
in polyurethane foam for crude oil sorption. The foams (lignin 0–20 wt%) were characterized …

Polymeric foams derived from renewable sources are a requirement of the modern world
due to increasing concern about the environment and various issues related to petroleum …

Rigid polyurethane foams (RPUF) were fabricated using rapeseed oil-based polyol and
polyols of petrochemical origin, which were tested using differing weight ratios. The aim of …

In this work the preparation of viscoelastic bio-based polyurethane foams (PUFs) using
polyols obtained via acid liquefaction of coffee grounds wastes has been optimized. In a first …
