Haina, Sagheer Gul, Muhammad Awais, Saira Jabeen, Muhammad Farooq
Journal of Renewable Materials, Vol.8, No.10, pp. 1305-1326, 2020, DOI:10.32604/jrm.2020.010037

Recent Developments on Biobased Materials and Composites)
Abstract This review efficiently covers the research progress in the area of polymer bio composites in perspective of the modern-day renewable materials. In the
last decade, attraction towards the bio-composite based systems has been the topic
of interest due to their potential as a substitute of conventional materials produced
in important manufacturing industries. Recently, preparation of biocompatible and
biodegradable polymer composites is an important achievement as an alternative
of petrochemical based renewable products. Successful production of eco-friendly
bio-composite materials have been achieved with natural fibers viz jute, bamboo,
hair, flex, wool, silk and many others instead of synthesized fibers like carbon,…

Tao Gui, Shichen Cai, Zhiqiang Wang, Jianhui Zhou
Journal of Renewable Materials, Vol.8, No.9, pp. 1053-1066, 2020, DOI:10.32604/jrm.2020.011645

Abstract Eucalyptus is a major fast-grown species in South China, which has the
potential for producing structural wood products such as cross-laminated timber
(CLT). Aspect ratio (board width
vs. board thickness) of eucalyptus lumbers is
small due to the small diameter of fast-grown eucalyptus wood. To evaluate its
rolling shear modulus and strength for potential CLT applications, three-layer
hybrid CLT shear block specimens with different aspect ratios (2,4,6), were tested
by planar shear test method. Digital image correlation (DIC) was employed to
measure the rolling shear strain distribution and development during the planar
shear tests. The mean values of rolling shear…

Abstract The use of agricultural straw for algal bloom control has been studied
for more than 30 years. In this article, we have reviewed the promising potentials
of using agricultural straw as source of anti-algal agents, including the effectiveness of each major straw type so far used in this regard, and the investigated algal
species. Various pre-treatment methods have also been widely reviewed. Signifi-
cant progress has been made in natural product chemistry and molecular biology
with regards to agricultural straw, especially in relation to the extraction of antialgal allelochemicals, degradation processes of agricultural straws and the
mechanisms through which these…

Abstract Starch nanocrystals (SNC) were prepared from maize starch using
ultrasound assisted acid hydrolysis. The process takes less time for the generation
of SNC, which is advantageous over conventional acid hydrolysis. The synthesized SNC were characterized using X-ray diffraction, dynamic light scattering,
zeta potential and transmission electron microscopy (TEM). Particle size and
TEM data show that the particles were near to 150 nm, with oval morphology.
The SNC with higher surface charge are obtained with this innovative approach
as compared to conventional acid hydrolysis. Because of high surface charge
and oval like morphology, the SNC performed well in reinforcing a polyurethane…

Abstract This work reports a comprehensive study on poly (Ethylmethacrylateco-Acrylonitrile) Poly(EMA-AN) nanocomposites reinforced with a hybrid mixture of nanoreiforcements based on nanocrystals of cellulose (NCC) (1 or 5% wt)
and halloysite nanotubes (HNTs) (1 or 5% wt). The morphology, thermal and
mechanical properties of these nanocomposites were characterized. Homogeneous
dispersion of the nanofillers has been shown by scanning electron microscopy. A
significant increase of the rubbery modulus and glass transition temperature were
obtained upon filler addition, due to the reduction of mobility of the matrix
macromolecular chains. On the other hand, compared with the neat Poly(EMAAN), the storage modulus of the…

Abstract Oil palm ash (OPA) is an agro-industry waste and it has disposable
problems. In the present study, an effort was made for value addition to OPA by
incorporating it as a micro-filler in different concentration (0, 10, 20, 30, 40, and
50%) and sizes (100, 200, and 300 mesh size particles) in the epoxy matrix.
Prepared micro OPA was having a crystallinity index of 65.4%, high inorganic
elements, and smooth surface morphology. Fabricated composites had higher
void content as compared to neat epoxy matrix. Mechanical properties of
fabricated composites had a maximum value at 30% loading of 300 mesh-size
filler…

Abstract The present study deals with the intensified synthesis of starchpolyaniline
(starch-PANI) nanocomposite using an ultrasound-assisted method.
Starch is a key component in this nanocomposite, which acts as a backbone of the
nucleation of PANI. The Electrochemical property of the nanocomposite arises due
to the addition of PANI. This is one of green approach for the synthesis of bio
nanocomposite using ultrasound. The crystallinity of the composite is evaluated
using the Scherrer Formula. The starch-PANI nanocomposite was characterized by
XRD, FT-IR, Raman, XPS and TEM. The composite nanoparticles show spherical
morphology. The elemental composition of starch-PANI showed O 1s peak at…

Abstract Microencapsulation of neroline inside microcapsules having a
polyurethane shell based on β-cyclodextrin (β-CD) and hexane diisocyanate was
performed by interfacial polycondensation. The polyol nature of β-CD caused tight
crosslinking of microcapsules wall. Microcapsules of neroline were characterized
for their chemical composition and structure of the polyurethane shell by FTIR
spectroscopy, thermogravimetric analysis, optical and electron microscopy, light
scattering and electrophoresis measurements. Core content and encapsulation
yield were 15% and 60%, respectively. Spherical microcapsules of mean diameter
29 μm were slightly cationic with an isoelectric point of 6.3. Neroline-loaded
microcapsules were fixed on cotton fabric using an impregnation technique. The
functionalized…

Abstract Plant components are an inexhaustible source for the construction of
bio-based materials. Here we report, for the first time, the elaboration of
biobased cellulose nanocrystals (CNC)/xyloglucan (XG) hydrogels. XG is a
hemicellulose displaying a great affinity for cellulose surface and can be thus
irreversibly adsorbed on CNC. Properties of the hydrogels were investigated by
varying the molar mass of XG either by enzymatic treatment with Endoglucanase
(EG2) or physical fractionation by ultrasound (US). Fractions were
characterised by high-performance size exclusion chromatography (HPSEC) and
their monosacchari decompositions were determined. Three fractions with high,
average and small molar mass, (800, 300 and…
