Sulfonated polysulfone is a polymer with unique properties, widely used in multiple fields. Sulfonated polysulfone has broad application prospects in membrane separation, electronic materials, pharmaceuticals, and other fields.
1. Membrane separation: Sulfonated polysulfone membranes are widely used in membrane separation processes such as reverse osmosis (RO) and ultrafiltration (UF) due to their excellent thermal stability, acid resistance, and high separation performance. These membranes play important roles in water and solution treatment, wastewater treatment, seawater desalination, and more.
2. Electrolyte membrane: Sulfonated polysulfone membrane has good ion exchange performance and high proton conductivity, so it is widely used in energy related fields such as fuel cells, hydrogen production from water electrolysis, and electrolyte membrane batteries.
3. Drug delivery: Due to the small pore size and good biocompatibility of sulfonated polysulfone membranes, they can be used for the preparation of drug delivery systems. Sulfonated polysulfone membranes can serve as carriers to control the release rate and direction of drugs, and are used for sustained-release drugs or therapeutic systems that control drug release.
4. Membrane electrode: Sulfonated polysulfone membrane is commonly used as the electrolyte layer of membrane electrode materials, for preparing devices such as electrochemical sensors, lithium-ion batteries, and supercapacitors. Sulfonated polysulfone membranes can provide good ion transport performance and electrochemical stability.
5. Membrane support: Sulfonated polysulfone membranes are commonly used as support layers for other membrane materials due to their heat resistance and chemical stability. For example, using it as a support layer for polyimide (PI) membranes can improve the mechanical strength and stability of the membrane.

SPSF - Properties
Open Data Unverified Data
Sulfonated polysulfone is a polymer compound with unique properties, obtained by replacing some of the hydrogen atoms on the benzene ring of the polysulfone with sulfonic acid groups. The following are some properties of sulfonated polysulfone:
1. High temperature stability: Sulfonated polysulfone can still maintain its structural stability at high temperatures, with a thermal decomposition temperature of over 400 ° C, thus possessing excellent heat resistance and maintaining its performance stability in high temperature environments.
2. Mechanical properties: Sulfonated polysulfone has good mechanical strength and rigidity, and its bending strength and tensile strength are relatively high. At the same time, it also has a high tensile modulus and exhibits excellent deformation resistance characteristics.
3. High solubility: Compared with unsulfonated polysulfone, sulfonated polysulfone has higher solubility in common organic solvents such as dimethyl sulfoxide, sulfoxide, ether, etc. This makes sulfonated polysulfone easier to process and prepare in solution.
4. Good electrical performance: Sulfonated polysulfone has high ion conductivity and can be used as an electrolyte material in fields such as fuel cells. Under acidic and alkaline conditions, sulfonated polysulfone can absorb and conduct ions, exhibiting good ion conductivity.
5. Chemical resistance: Sulfonated polysulfone has good corrosion resistance to most organic solvents, acids, and bases, and is not easily corroded by chemical substances. This makes sulfonated polysulfones have broad application potential in certain specific fields, such as material coatings, membranes, and membrane separation.

SPSF - Production methods
Open Data Unverified Data
Sulfonated polysulfone is an important functional polymer material with excellent temperature resistance, corrosion resistance, and electrical insulation performance. Different experimental conditions and raw materials can make certain adjustments to the preparation process to obtain the desired sulfonated polysulfone material. The manufacturing process mainly includes the following steps:
1. Polymerization reaction: Firstly, poly (arylene sulfone) is synthesized through polymerization reaction, with commonly used raw materials being difunctional benzodiazine and difunctional sulfone. Polymerization reactions are generally carried out using solution polymerization or suspension polymerization methods, and the reaction conditions include appropriate solvents, catalysts, and reaction temperatures.
2. Solution treatment: Dissolve polysulfone in an appropriate solvent and apply appropriate temperature and pressure to completely dissolve.
3. Sulfonation reaction: The polysulfone solution is reacted with sulfonic acid compounds (such as concentrated sulfuric acid, chlorosulfonic acid, etc.) to introduce sulfonic acid groups on the benzene ring of the polysulfone. Sulfonation reactions are generally carried out at high temperatures and usually require a certain reaction time to ensure complete reaction.
4. Filter out residue: Filter out the reaction solution to remove residual non sulfonated polysulfone and other impurities.
5. Washing: Use appropriate solvents to react and wash sulfonated polysulfone to remove unreacted sulfonic acid compounds and other impurities.
6. Drying: Dry sulfonated polysulfone to a certain moisture content through appropriate drying methods (such as vacuum drying or hot air drying).

SPSF - Safety
Open Data Unverified Data
1. Toxicity: Sulfonated polysulfone has low toxicity under conventional usage conditions. However, during combustion, heating, or decomposition, toxic smoke and gases can be generated, which may pose a threat to human health.
2. Inhalation: Prolonged exposure to sulfonated polysulfone dust or its smoke may cause respiratory irritation and inflammation. It is recommended to use personal protective equipment, such as a breathing mask or protective goggles.
3. Eye contact: Sulfonated polysulfone entering the eyes may cause irritation and discomfort. If eye contact occurs, rinse with plenty of water and seek medical assistance.
4. Ingestion: Sulfonated polysulfone is not edible. If accidentally ingested, seek medical assistance immediately.
5. Skin contact: Short term contact usually does not cause significant irritation or inflammation. However, prolonged exposure may cause skin dryness, irritation, and allergic reactions. It is recommended to use gloves and other personal protective equipment, and wash hands promptly after contact.
6. Combustion characteristics: Sulfonated polysulfone will decompose at high temperatures, producing toxic smoke and gases such as sulfur dioxide. It has good self extinguishing and low combustion performance.
7. Storage and handling: Sulfonated polysulfone should be stored in a dry and ventilated place, away from sources of fire and open flames. During the handling process, please take appropriate measures to avoid inhaling dust or coming into contact with skin and eyes.
