Phenol: formaldehyde ratio was varied in the synthesis of phenol- formaldehyde resin and used to prepare the composites. These composites were then evaluated for their mechanical strength on the basis of tensile strength, compressive strength and wear resistance. Composite with better strength was characterized by IR, SEM, XRD, TGA/DTA and further studies were carried out for its physico-chemical and mechanical properties like viscosity, modulus of rupture (MOR), modulus of elasticity (MOE) and stress at the limit of proportionality (SP)etc.

Resin Curing

A Titanium-modified phenol-formaldehyde resin (Ti-PF) was prepared. FT-IR was adopted to characterize the molecular structure of the modified resin. And the curing behavior and curing kinetic characteristics were studied by differential scanning calorimetry (DSC). The initial curing temperature Ti, the exothermic peak temperature Tp and the end curing temperature Td of Ti-PF are 153.1°C, 172.5°C and 193.9°C, respectively, all about 10°C higher than that of the unmodified phenolic resin. The Kissinger and Crane equations were applied to establish the curing kinetic parameters of Ti-PF. The kinetic analysis indicates the activation energy for the Ti-PF is 79.9kJ•mol-1, lower than that of the unmodified phenolic resin(87.6kJ•mol-1). In addition, the thermal degradation behavior of the cured Ti-PF was studied by thermal gravimetric (TG) method. TG results show that the char yield of Ti-PF is 73.3% at 850°C, while that of the unmodified phenolic resin is only 62.3%. It demonstrated that titanium-modified phenolic resin has much better thermal stability compared with the unmodified one.

The paper evaluates the effectiveness of the use of graphene nanostructures in the purification of lead (II) ions to improve the ecological situation of water bodies. The mechanisms and characteristic parameters of the adsorption process were analyzed using empirical models of isotherms at temperatures of 298, 303, 313 and 323 K, which correspond to the following order (based on the correlation coefficient): Langmuir (0.99) > Temkin (0.97) > Dubinin – Radushkevich (0.90). The maximum adsorption capacity of the material corresponds to the range from 230 to 260 mg/g. We research the equilibrium at the level of thermodynamic parameter estimates, which indicates the spontaneity of the process, the endothermic nature and structure change of graphene modified with phenol-formaldehyde resin during the adsorption of lead (II) ions, leading to an increase in the disorder of the system.
