Thermally insulating materials from renewable and readily available resources are in high demand for ecologically beneficial applications. Cellulose aerogels made lignocellulosic waste have various advantages. However, they fragile breakable when bent or compressed. In addition, cellulose flammable weather-sensitive. Hence, to overcome these problems, this work included the preparation of polyurethane (PU)-based nanofiber (CNF) that had flexibility, flame retardancy, thermal insulation....
Potential of crystalline nanocellulose (CNC), as green reinforcing filler, has been evaluated for the preparation natural rubber (NR) composites. CNC is derived from a source (ramie fiber) and its surface modified with different organosilanes to strengthen rubber‐filler interaction at interface. It found that, although 2.5 phr (parts per hundred parts rubber) loading mechanical property NR composites improved, it deteriorates 5 loading. Surface modification by very useful overcome this...
Materials such as cellulose and its derivatives are attracting growing attention worldwide to recognize their potential in responding increasingly complex technological requirements. The rising demand for multifunctional materials may be fulfilled with controllable functionalities by using self-assembling techniques. Photonic stimuli-responsive based on can shift color reversibly when external inputs. Cellulose nanocrystals (CNCs) biorenewable that self-assemble themselves into a chiral...
Abstract Hybrid composite films are largely preferred over neat because of their superior thermal, mechanical, chemical, and hydrophobic properties. The hybrid film has a wide range use, including space, defense, electronics, packaging, engineering applications. Fabricating multifunctional with biodegradable polymer filler such as cellulose nanocrystals become popular in recent years an alternative to conventional plastics. In this paper, hydroxylated boron nitride (BN) nanoparticles CNC...
Klippel-Trenaunay syndrome and Sturge-Weber are rare disorders with neurologic cutaneous signs of vascular origin. Phakomatosis pigmentovascularis represents the association widespread, aberrant, persistent nevus flammeus pigmentary abnormalities. We describe a case features suggestive overlap between them. A ten-month-old boy presented seizures, developmental delay, skin lesions on face, trunk legs, buphthalmos right lower limb hypertrophy. CT scan head showed atrophy brain calcification....
Nanofibrillated cellulose (NFC) and polymethylsilsesquioxane (PMSQ) based aerogel are prepared by the sol-gel method. The objective of this work is to study impact surfactant base catalyst on thermal mechanical performance corresponding aerogel. rheological premonitory assists in predicting bulk properties chemical structure studied Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), photoelectron (XPS), solid-state nuclear magnetic resonance (NMR). microtomographic...
The organic photonic film is one of the important materials in optical, bioengineering, and sensing applications. It a task to achieve excellent mechanical properties foldability biopolymer composites having chiral nematic structures without sacrificing their iridescence. Herein, we have proposed an approach preserve lock self-assembled cellulose nanocrystal (CNC) films based on agro-waste between layers poly(lactic acid) (PLA)/polycaprolactone (PCL) biocomposite. were tweaked by doping with...
Abstract Bio‐inspired iridescent materials can possibly replace organic dyes and pigments, however, fabricating that resemble the appearance of absorbing pigments is challenging. Extracting cellulose nanocrystals (CNCs) from waste biomass a sustainable practice in light socio‐economic environmental concerns. In an attempt, CNCs sugarcane bagasse are isolated through acid hyrdolysis. Stable anisotropic dispersions doped with polyvinylpyrrolidone (PVP). Iridescent composite films cast these...
Abstract Cellulose nanocrystals (CNCs) have received an abundance of attention because their distinctive chiral nematic structure and exceptional optical characteristics. However, the use free‐standing films is constrained by inherent stiffness brittleness. In this work, CNC with robust mechanical properties are prepared simply coating them polymeric spherulites. Maleic anhydride‐grafted polypropylene (PP‐g‐MA) used to coat films. The coated were also analyzed using polarized microscope. It...
