“…The silanized cellulose aerogel prepared by Nguyen et al has an adsorption capacities of 4~12 g/g for toluene and vacuum pump oil [32]. The maximum adsorption capacities of microcrystalline cellulose aerogel prepared by Luo et al to pump oil and linseed oil was 10.63 and 11.44 g/g [33]. The adsorption capacities of CMC/graphene oxide aerogel prepared by Xiang et al to organic solvents such as methanol is 10~21 g/g [34].…”

In this study, composite aerogels with excellent mechanical properties were prepared by using carboxymethyl cellulose (CMC) as raw materials, with carboxylic carbon nanotubes (CNTs) as reinforcement. By controlling the mass fraction of CNTs, composite aerogels with different CNTs were prepared, and the surface morphology, specific surface area, compressive modulus, density and adsorption capacities towards different oils were studied. Compared to the pure CMC aerogel, the specific surface areas of CMC/CNTs were decreased because of the agglomeration of CNTs. However, the densities of composite aerogels were lower than pure CMC aerogel. This is because the CNTs were first dispersed in water and then added to CMC solution. The results indicated that it was easy for the low CMC initial concentration to be converted to low density aerogel. The compressive modulus was increased from 0.3 MPa of pure CMC aerogel to 0.5 MPa of 5 wt % CMC/CNTs aerogel. Meanwhile, the prepared aerogels showed promising properties as the adsorption materials. Because of the high viscosity, liquid possesses strong adhesion to the pore wall, the adsorption capacity of the CMC aerogel to the liquid increases as the viscosity of the liquid increases.

“…Hydrogels are made by techniques such as solvent casting/particulate leaching [ 138 ], gas foaming [ 139 ], phase separation [ 140 ], melt molding [ 141 ], and freeze-drying [ 142 ] ( Figure 6 ). Hydrogels can be manufactured as films, coatings, nanoparticles, etc., and can act as semipermeable membranes through which fluid can flow in three dimensions.…”

Biomaterials to Prevent Post-Operative Adhesion

et al. 2020

Surgery is performed to treat various diseases. During the process, the surgical site is healed through self-healing after surgery. Post-operative or tissue adhesion caused by unnecessary contact with the surgical site occurs during the normal healing process. In addition, it has been frequently found in patients who have undergone surgery, and severe adhesion can cause chronic pain and various complications. Therefore, anti-adhesion barriers have been developed using multiple biomaterials to prevent post-operative adhesion. Typically, anti-adhesion barriers are manufactured and sold in numerous forms, such as gels, solutions, and films, but there are no products that can completely prevent post-operative adhesion. These products are generally applied over the surgical site to physically block adhesion to other sites (organs). Many studies have recently been conducted to increase the anti-adhesion effects through various strategies. This article reviews recent research trends in anti-adhesion barriers.

Chitosan films were used to remove heavy oil from connate water, deionized water, and seawater. In this research, chitosan-starch films were modified with natural extracts from cranberry, blueberry, beetroot, pomegranate, oregano, pitaya, and grape. These biodegradable, low-cost, eco-friendly materials show an important oil sorption capacity from different water conditions. It was observed that the sorption capacity has a clear correlation with the extract type, quantity, and water pH. In order to understand the physical and chemical properties of the films, they were analyzed according to their apparent density, water content, solubility, and swelling degree by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), gas chromatography-mass spectroscopy (GC-MS), and the determination of surface area using the Brunauer Emmett Teller (BET) method. The results indicate that chitosan-starch films modified with natural extracts can be successfully applied for environmental issues such as oil spill remedy.
