Abstract: The desired phase-transition temperature and enthalpy of phase change materials are different in different application fields.
Introduction Phase change materials (PCM) take advantage of latent heat that can be stored or released from a material over a narrow temperature range.

The choice of electrode materials is very important in the EDM machining process.
Elemental nickel on the surface materials increased, while nickel content elements in materials electrode were more than 15 percent, as shown in (Fig 2d).

When the goal is to join materials with a different nature, like metals and polymer-based materials, the challenge is even much greater.
The tested base materials were PLA and PETG filaments with a diameter of 1.75 mm.

However, some plastic materials, such as polrvinyl chloride, polystyrene, are unsuitable for being used as the package material for the reason of features of the materials or the environment condition.
The MIR and NIR spectra of the two materials were collected under the same experimental condition. 2nd derivative was applied to the MIR and NIR micro-images. 2nd derivative compare correlation images of the two materials were acquired with 2nd derivative spectra of the two materials as reference respectively, meanwhile the compare correlation images of the two materials were acquired with raw spectra of the two materials as reference respectively. 2nd derivative chemimap images of the two materials were acquired, which were compared with the raw chemimap images.
Figure 1B is the MIR spectra of the two materials.
Figure 1D is the NIR spectra of the two materials.

After the fundamental characterization of these materials, the materials were processed mechanically preparing the materials to be extruded as 3D-printing filament.
The shredded materials were then placed in a drying oven overnight to reduce moisture in the plastic materials.

Experimental results showed that different solid materials had different biological affinity, which showed that the growth of biofouling was influenced by material surface properties.
They are as follows: Input1: carbon content of the surface materials (mass percentage, hereinafter the same), % Input2: hydrogen content of the surface materials, % Input3: oxygen content of the surface materials, % Input4: flow rate, m/s While the output of the model was the average biofouling amount: output, mg/cm2 In this case, select the 22 kinds of surface materials from reference [8] as the training samples.
The network were trained by the 22 kinds of surface materials, with hidden layer nodes automatically increasing from 1 node by examining the output errors of the network.
