Flame retardancy, thermal and mechanical properties of sulfonate-containing polyhedral oligomeric silsesquioxane (S-POSS)/polycarbonate composites

Pyrolysis products and thermal degradation mechanism of intrinsically flame-retardant carrageenan fiber

“…This group can exert an important inuence on pyrolysis mechanism of carrageenan. 15,16 Also, S]O intensity became stronger with an increase in temperature. The groups of S]O primarily remain in residue rather than releasing in pyrolysis gas, which fully embodies the principle of environmental protection.…”

“…In addition, carrageenan molecules have certain number of sulfate ester, which could be another plausible reason behind better ame retardancy of CAF as compared to ALF or AGF. 15,16 a The minimum concentration of oxygen in an oxygen/nitrogen gas stream mixture to keep combustion. b The time needed to achieve sustained ame combustion at a particular irradiance.…”

“…[9][10][11][12][13][14] Also, sulfate bases can play a key role in ame retardancy when carrageenans are spun into threads. 15,16 Recently, most of textiles have been dealt with phosphorusbased ame retardant, halogen-based ame retardant, inorganic ame retardant, and nitrogen-containing ame retardant to reduce the ammability. [17][18][19][20][21][22][23][24] The applications of those ame retardants have been the most efficient ways of reducing the economic loss and ensuring personal security when the re accident happened suddenly.…”

Hyperbranched Polysiloxanes Based on Polyhedral Oligomeric Silsesquioxane Cages with Ultra-High Molecular Weight and Structural Tuneability

“…The performance of polymer 1 during heating in the air in terms of TD 5 and char value is consistent with the above assumption of the roles of POSSs and phenyl groups. Polymer 1 is by far one of the most thermally stable polysiloxanes ever reported [47][48][49].…”

Synthesis and properties of POSS-containing gallic acid-based non-isocyanate polyurethanes coatings

“…It has been demonstrated that the modification of polymers with POSS could significantly improve the properties of materials, such as mechanical properties, thermal stability, water tolerance, fire resistance and dielectric properties [27][28][29][30]. Over the past few decades, various strategies such as incorporation of functional POSS have been proposed to improve the properties of polyurethanes [31][32][33][34].…”
