Abstract:
In this study, the novel sodium alginate/feather keratin-g-allyloxy polyethylene glycol (SA/FK-g-APEG) composite phase change fiber was designed and fabricated via centrifugal spinning for the first time. The chemical structure of the composite fiber was characterized by FT-IF and NMR, the thermal property was characterized by DSC, and the morphology features was analyzed by SEM and EDS. The NMR result demonstrates there are chemical shifts at δ = 155.6 ppm indicating CC has been successfully introduced via acylation,and at δ = 70.06 ppm indicating that allyloxy polyethylene glycol (APEG) has been grafted onto feather keratin (FK). The DSC results show an decline in the endothermic peak related to melting of the APEG from 54.87 °C to 40.1 °C (phase change fiber), indicating the strong interaction between sodium alginate (SA) and feather keratin-g-allyloxy polyethylene glycol (FK-g-APEG). The mechanical properties test shows that the optimal spinning temperature is 40 °C, and the optimal Centrifugal speed is 500 r/min.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

Sodium ions make up approximately 90% of extracellular cations, with a normal blood plasma concentration of 136–148 mEq/L. A decrease in blood volume and pressure triggers the release of renin from granular cells in the juxtaglomerular complex (JGC), primarily...

Work Done During Volume Change
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as
