임의의 계면활성제의 도움없이 수성 용액 또는 물에 분산성인 표면 처리된 중합체 입자. 소수성 중합체 입자의 표면 처리는 표면 에너지를 증가시키고 입자의 표면을 친수성이 되게 하기 위해 수행되며, 이로써 물 또는 수성 용액에 중합체 입자를 분산시키기 위한 계면활성제를 필요로 하지 않는다. 이처럼 무계면활성제 슬러리는 섬유 강화 열가소성 복합 구조를 제작하기 위한 표면 처리된 입자로부터 제조될 수 있다. Surface-treated polymeric particles which are dispersible in water or an aqueous solution without the aid of any surfactant. Surface treatment of hydrophobic polymeric particles is carried out to increase the surface energy and to render the surfaces of the particles hydrophilic, thereby eliminating the need for a surfactant to disperse the polymeric particles in water or an aqueous solution. As such, a surfactantless slurry can be formed from the surface-treated particles for the fabrication of fiber-reinforced thermoplastic composite structures.
